xrdp sink / source pulseaudio modules

pulseaudio-module-xrdp's Issues

Audio has long delay in being sent from server.

Hello, I've followed your guide on Ubuntu 19.04 with Xorg, SLIM and XFCE4. XRDP was installed with this custom compiled pulseaudio module for xrdp.

I'm experiencing large delays in audio when using the Remmina RDP connection to the XRDP server. Upon initial login to the server and starting an audio feed and seeing pavumeter showing the signal levels of xrdp sink are outputting the audio has a 10-13 second audio delay. As the time in the XRDP session increases, the delay becomes longer and longer. If I log out and back in to start a new session the audio delay is back to the initial 10-13 seconds.

Also, if I close a session and reconnect to the preexisting session the audio delays are still there. This leads me to believe the issue is on the server side.

Please let me know how to output any useful debug information. Thanks!

ERROR: Program 'doxygen' not found or not executable

Im accessing a Kali Linux VM over XRDP and I have the problem, that I have no sound/audio.
For that I saw the instructions in this repository and started to follow the steps.

Now I have the following problem:
If I run the "install_pulseaudio_sources_apt_wrapper.sh" as sudo , I get this message:

** schroot failed. Check log file /var/tmp/pa-build-root-schroot.log

The log-file contains following error:

Do you know how to fix this?

I had to manually modify /etc/xrdp/pulse/default.pa at the end of the installation procedure

I followed the «other distro» installation steps and it went fine. After reopening a session with xrdp, the session was still using the null sink.
I had to modify /etc/xrdp/pulse/default.pa to make it work.

Maintain this module in pulseaudio upstream?

Hi,

recently I packaged pulseaudio-module-xrdp for Kali Linux, see: https://pkg.kali.org/pkg/pulseaudio-module-xrdp.

In the process, I found out that it needs the whole PulseAudio source code to build, as it requires PA internal library. It makes the packaging process slightly awkward, although it's doable. But from a packager point of view, it would be easier if this code was just part of PulseAudio itself.

So I was curious and wanted to ask the question here. Did you consider approaching the PulseAudio maintainers and offer to maintain this module within the PA source tree?

Cheers,

Arnaud

sink_process_msg: not running error during speaker-test

i am using xfreerdp to connect to xrdp on the same computer with pulse sound.

inside xfreerdp session, i run speaker-test, but the noise stutters, it stops for several seconds every tens of seconds.

i can see error message "sink_process_msg: not running" in syslog.

after i set the log-level to debug in /etc/pulse/daemon.conf, i can see what follows with command:

Volume meter works but sound not - Socket name mismatch

Following most of tips to take sound working I have no success. I have working volume meter but sound is silence.
I found this clue but I can't confirm is it well defined:
https://bbs.archlinux.org/viewtopic.php?id=240329

It is true that there is some socket name mismatch?

1 second latency

I'm trying to get xrdp working on Ubuntu 22.04 LTS VM running on Proxmox with PCI Passthrough of my Nvidia 3090.
I have installed xrdp with the xrdp-installer script (https://c-nergy.be/blog/?p=18725) which I have modified to get acceleration going with my Nvidia card according to this gist: https://gist.github.com/Nexarian/0eb26a3284b21b55b6e1e8653ed88ec9.

Everything works great except I'm getting about 1-second delay on the audio stream. I have tried every tip and trick that I have found, but nothing really helps. The only thing that looks to help sometimes is to fast forward and rewind the video a few times and then all of a sudden I start hearing some audio stutter, and the video and audio are syncing up. After doing that everything works fine both in a browser and if I play a video with say mpv. If I reboot it's all out of sync again :(

Listing all the things I have tried would make this a very long thread, but here are some of them:

• Tried it on several versions of Ubuntu: 20.04, 22.04 LTS, 22.12, 23.04 (The last two with pipewire patch from here: https://c-nergy.be/blog/?p=18772)
• Disabling all the modules I can in default.pa
• tschedule=0, tschedule=1
• and several other things :(
• Enabling and disabling MSR

What I have not tried is running it on bare metal as the point of all of this is to have RD to my VMs on proxmox.

I don't know if this is an issue with pulseaudio-module-xrdp, xrdp, but those to modules and the proxmox server are the only thing that has remained unchanged between all the things I have tried.

Really hope someone here can help to get this sorted. It's basically the only thing keeping this from being a "perfect" solution for my needs.

Thank you!

The module crashes pulseaudio in container.

I am running Archlinux in container. Without this module, pulseaudio worked just fine. With this module, pulseaudio exited with message in dmesg:

pulseaudio[14616] trap invalid opcode ip:7fb2b1eb73c4 sp:7ffee7249330 error:0 in module-xrdp-sink.so

Debian 10: no sound, Code 11 - module-xrdp-sink.c: sink_process_msg: not running

I followed the steps on the README on Debian Buster and I see the "xrdp sink" on pulseaudio but hear no sound.

I stopped pulseaudio in systemd, made sure no instances were running and ran pulseaudio -vvvv as a regular user on a terminal. I see this in stdout:

How can I troubleshoot this further?

For more info, I added these lines to /etc/pulse/default.pa (the others were already present):

### XRDP modules
.ifexists module-xrdp-sink.so
load-module module-xrdp-sink.so
.endif
.ifexists module-xrdp-source.so
load-module module-xrdp-source.so
.endif

when run this command "scripts/install_pulseaudio_sources_apt_wrapper.sh"

Remove old build root /var/lib/pa-build/alarabi before running this script

What Should I do

Ubuntu installation script fails under ZFS, but not EXT4

I have a completely fresh (VM) install of xubuntu 21.10 in a completely unmodified configuration. After install, I run apt update, apt upgrade, apt install xrdp, and then proceed to follow the Debian/Ubuntu build instructions.

If the filesystem chosen during install is EXT4, everything works correctly, virtual user sessions have audio, all is well.

If the filesystem chosen during install is ZFS, the process reaches - Building PA Sources. Log file in /var/tmp/pa-build-testuser-schroot.log and then ** schroot failed. Check log file /var/tmp/pa-build-testuser-schroot.log

Here are the content of the log:

E: Failed to change directory '/home/testuser/pulseaudio-module-xrdp': No such file or directory
I: The directory does not exist inside the chroot. Use the --directory option to run the command in a different directory
E: Failed to change directory '/home/testuser/pulseaudio-module-xrdp': No such file or directory
I: The directory does not exist inside the chroot. Use the --directory option to run the command in a different directory

E: Failed to change directory '/home/testuser/pulseaudio-module-xrdp': No such file or directory
I: The directory does not exist inside the chroot. Use the --directory option to run the command in a different directory

The installation is completely unmodified other than choosing ext4 vs zfs in the installer. I am running the installer through the graphical display (not an xrdp session or ssh) in both cases. On the ZFS system many directories are separate mount points (including each individual home directory), I'm not sure if schroot / any other commands used by the script are struggling to traverse mount points.

Fedora 33 Beta No Audio / Sound

Hi,

I compiled the module in two ways:

1. Followed the CentOS 7.5 and greater
2. Followed the other distro method by downloading the source tarball for xrdp 13.99.2.

Both methods compile without errors and all the ini files and such appear to be correct but the module fails to load as follows;

Oct 11 12:54:13 localhost.localdomain pulseaudio[1681]: Failed to load module "module-xrdp-source" (argument: ""): initialization failed.
Oct 11 12:54:13 localhost.localdomain pulseaudio[1681]: Invalid sample format specification or channel map

Oct 11 12:54:13 localhost.localdomain pulseaudio[1681]: Invalid sample format specification or channel map

TIA for any help.

Pulseaudio server not supported on Ubuntu 22.10

Previously on Ubuntu 22.04 these modules worked. The sound was not perfect (very slow and stuttering) but it was audible. Today I decided to upgrade to a newer Ubuntu version and since then, despite the code built and installed fine, I don't see xrdp sink output device in GNOME Settings. Obviously, neither paplay nor YouTube in Firefox don't produce any sound. Debugging load_pa_modules.sh showed the following malformed behavior.

$> sh -x /usr/libexec/pulseaudio-module-xrdp/load_pa_modules.sh
+ status=0
+ [ -n 1 -a -n /run/xrdp/sockdir ]
+ [ -z xrdp_chansrv_audio_out_socket_10 -o -z xrdp_chansrv_audio_in_socket_10 ]
+ pactl unload-module module-xrdp-sink
+ pactl unload-module module-xrdp-source
+ pactl load-module module-xrdp-sink xrdp_socket_path=/run/xrdp/sockdir xrdp_pulse_sink_socket=xrdp_chansrv_audio_out_socket_10
Failure: No such entity
+ echo ? Can't load pulseaudio xrdp-sink
? Can't load pulseaudio xrdp-sink
+ status=1
+ pactl load-module module-xrdp-source xrdp_socket_path=/run/xrdp/sockdir xrdp_pulse_source_socket=xrdp_chansrv_audio_in_socket_10
Failure: No such entity
+ echo ? Can't load pulseaudio xrdp-source
? Can't load pulseaudio xrdp-source
+ status=1
+ exit 1

Then I tried to trace pactl (don't know if it makes any sense) but it didn't give me any new clue. I attached the log here. Maybe someone will see anything interesting in it - pactl.log.

What else can I do to track the problem down?

Note: Despite I upgraded Ubuntu (i.e. not installed it from scratch) I purged everything related to pulseaudio and alsa and reinstalled those packages. After that I rebuilt XRDP modules again.
Another note: There are no problems with the sound in non-XRDP (local) setup.

Create packages for Debian/CentOS/Fedora/

Currently only Ubuntu 18.04 Bionic has a package in launchpad. However if you install xrdp, you get a Suggested package xrdp-installer-pulseaudio but has no source available. If I want to get audio through xrdp, I have to build it myself. That is not a acceptable solution for regular users. Users should simply install it from package manager. So please create binaries and publish them to EPEL (Fedora/CentOS) and Debian SID (since it needs to be tested by Debian team before being pushed to stable).

An alternative is to simply release the binaries on the Release page, which is easier than building yourself but has the problem of self-maintenance. There should be auto-updates using CI/CD to the repositories listed above.

Build failed on Ubuntu22.04

Hi, I follow the Wiki to install this module, when I try to build this module with the command ./bootstrap && ./configure PULSE_DIR=~/pulseaudio.src , I got the following error:

No sound on Debian Buster.

Just upgraded to Debian Buster. Xrdp sound had previously worked fine with the xrdp-pulseaudio-installer package in Stretch. However that package is no longer available so I followed the instructions here to build manually.

I was able to successfully build the xrdp source and sink libraries. They get loaded and I can connect with the volume control. I did have to modify /etc/pulse/default.pa to get them to load, as /etc/xrdp/pulse/default.pa seems to be getting ignored.

When I start playback of a YouTube video, I get no sound and the following message repeats in syslog as long as audio is playing:

Jul 13 12:42:19 robin pulseaudio[1424]: E: [xrdp-sink] module-xrdp-sink.c: 1 block_usec 30000
Jul 13 12:42:19 robin pulseaudio[1424]: E: [xrdp-sink] module-xrdp-sink.c: 1 block_usec 30000

The volume control (pavucontrol) does show audio coming from Chrome, but the sound never gets to my rdp client.

ETA: It also seems that it takes a long time to connect to the pulseaudio server. The pavucontrol client displays a "trying to connect" message for about 30 seconds before showing the main screen.

wrapped_script: Permission denied -- proposed fix

On my ubuntu 22.04 system, when copying wrapped_script it's getting moved over (sudo cp) and gets file permissions that schroot can't run with as a regular user. I think this could be fixed by changing to chmod a+rx (this worked for me) or switching to cp -a (didn't test, but probably would work).

Building against Pulseaudio 15.0 Meson build system

Pulseaudio 15.0 uses Meson now making it incompatible with the current build.
I am not sure what is involved with making a usable module, but currently even after a Meson configure/build you get back:

module-xrdp-sink.c:26:10: fatal error: config.h: No such file or directory
   26 | #include <config.h>

When attempting to build against Pulse 15.0 source files.

Any current workarounds or planned changes ? This effects all the rolling distros out there.

Cannot build it on Linuxmint 20.04

Anybody can help?
Thank you very much.

crash when set channels = 6

https://github.com/neutrinolabs/pulseaudio-module-xrdp/blob/devel/src/module-xrdp-sink.c#L363

pulseaudio has an assertion pa_frame_aligned on function pa_sink_render

https://github.com/pulseaudio/pulseaudio/blob/master/src/pulsecore/sink.c#L1234

it restricts request_bytes must be divisible by channels number * 1, 2, 3 or 4

on surround sound, u->sink->thread_info.max_request is always greater than 16 * 1024. so request_bytes will be 16384. it can not to be divisible by 6.

do not install `*.la`

it is not needed. pulseaudio only recognizes *.so files in moduledir.

Wiki updating?

I found out one cannot pull request Wiki pages on GitHub.

I just went through the PA module setup process on Debian buster and would like to correct some small inconsistencies (paths, use of sudo for some parts and not for others when running as regular user, etc.), update with Debian stable info, and most importantly, a workaround for Debian bug #923203 — no sound on Debian buster with sysvinit (namely, adding autospawn = yes to `~/.config/pulse/client.conf).

How would I go submitting those?

module-config.h is not loaded

These macros are defined in module-config.h, generated by configure script.

#define PACKAGE "pulseaudio-module-xrdp"
#define PACKAGE_BUGREPORT "[email protected]"
#define PACKAGE_NAME "pulseaudio-module-xrdp"
#define PACKAGE_STRING "pulseaudio-module-xrdp 0.1"
#define PACKAGE_TARNAME "pulseaudio-module-xrdp"
#define PACKAGE_URL ""
#define PACKAGE_VERSION "0.1"

However, module sources don't include module-config.h at all and actually, these macros are used. This is bad because pulseaudio upstream's information such as version and contact information is compiled in our modules.

#define PACKAGE "pulseaudio"
#define PACKAGE_BUGREPORT "pulseaudio-discuss (at) lists (dot) freedesktop (dot) org"
#define PACKAGE_NAME "pulseaudio"
#define PACKAGE_STRING "pulseaudio 11.1"
#define PACKAGE_TARNAME "pulseaudio"
#define PACKAGE_URL "http://pulseaudio.org/"
#define PACKAGE_VERSION "11.1"

Adding this to the sources includes our macro definition.

#include "module-config.h"

But compiler warns redifinition of macros. This is natural because they're both defined in pulse's config.h and our module-config.h.

In file included from module-xrdp-source.c:50:
../module-config.h:98:9: warning: 'PACKAGE_VERSION' macro redefined [-Wmacro-redefined]
#define PACKAGE_VERSION "0.1"
        ^
/ssd/tmp/ports/usr/ports/audio/pulseaudio/work/pulseaudio-11.1/config.h:605:9: note: previous definition is here
#define PACKAGE_VERSION "11.1"
        ^

Some how we need to integrate 2 config.h s and I'm working on this. Just for a record.

Still no audio after installing the PulseAudio XRDP Module

I installed xrdp on Debian 11, but I installed xorgxrdp 0.2.9.1 because the Bullseye version seems to have a bug where all I see is a black screen. RDP works, however, I don't hear anything. Looking at the xrdp github, it seems like I need to install the pulseaudio module for xrdp. I followed this guide https://github.com/neutrinolabs/pulseaudio-module-xrdp/wiki/README#install. I rebooted the Debian 11 and under the Settings / Sound, I see "xrdp sink" and I see it pulsating when I play some audio - e.g. youtube videos. But I still don't hear any sound.

I am on Fedora 36 and the clients that I am using are Remmina and Connections.

LICENSE: switch to LGPLv2.1

One of the source files lists APL2 another lists GPL2, others have no identification. Can the license information be clarified for this code?

make : fatal error on config.h

Hi,

I followed your readme for Ubuntu.

I've got the following error whith 'make' command to build xrdp source / sink modules :

Could you help me ?

Change the repository name

what about pulseaudio-module-xrdp? neutrinolabs/pulseaudio-modules is unique in our scope but not unique in the world.

When distro people create a package of this pulse module, they'll consider the package name.
Different distro might name differently. We should provide a unique name not to cause confusion.

configure script can't find libpulse.pc

I'm following the Ubuntu instructions in README.md and when I get to line 73:

./bootstrap && ./configure PULSE_DIR=/path/to/pulseaudio-11.1

configure throws a bunch of errors about not being able to find libpulse.pc. I added an additional env var to make it work for me:

./bootstrap && ./configure PULSE_DIR=/path/to/pulseaudio-11.1 PKG_CONFIG_PATH=/path/to/pulseaudio-11.1

I was going to PR a change to README.md but it looks like Travis is already building for Ubuntu, which suggests to me that it's something with my setup.

TL;DR: The invocation of configure might need an additional env var to work correctly.

Two other small notes, related to README.md:

1. If you follow the instructions to the letter, it looks like you're supposed to clone this repo in the directory containing the pulseaudio source code. I assume that's not harmful, though I opted to clone it in a different directory.
2. I had to read ./configure --help to realize that the value of the PULSE_DIR env var should be the path to the pulseaudio source code, not the bin. That could probably be clarified, though TBH I'm not sure what the wording should be.

Install fails on Raspbian GNU/Linux 11 (bullseye)

Wrong sampling rate in audio

Hi,

I'm using xRDP on Debian Buster on a Raspberry Pi and installed the pulseaudio-module-xrdp.

Although I can hear sound from the RDP session, the sound is played with a too low sampling rate. So everything sounds like being in slow motion and keeps getting more and more delay to video.

The modules have been build with pulseaudio-12.2 sources as well as respective dev libs. The RDP client is JumpDesktop on macOS and iOS.

Is there any way to control what sampling rate is used when a RDP client connects?

I need help to troubleshoot this: xrdp with audio in a NixOS container

NixOS has a feature where you can define declarative containers that run using systemd-nspawn.

Right now I am able to run xfce and access it using RDP. The RDP port is exposed on the host and right now I am able to do basically anything but listen to stuff.

The way how it's now working (Nix package and container) the session starts, asks for login and the desktop works fine. The module of this repo appears in audio sources and sinks fine, bars wiggle, almost no problem. Except that my client doesn't play anything, not even garbled noise that happens when sync is not right or something like that, just complete silence.

One hypothesis that I though is that is something about /dev/snd not available then I passed it as a volume and still same problem.

I also though that it for some reason may be a chromium issue and tested with firefox but same problem.

Microphone never leaves zero, even though I configure the client to use that. It may be a config that is not allowed.

The host system is a Desktop ready system but I am only exposing /home to /var/lib/something so it shouldn't cause any interference.

I am testing with Remmina (making sure that Advanced > Audio output mode is set to local) and Microsoft Remote Desktop on an Android phone.

You guys may know a detail I am missing.

Audio redirect not automatically starting

Auto starting of the xrdp sink doesn't seem to be working for all users, and I suspect this is due to a combination of restrictive umask issues and missing system-wide configuration. Though it does not auto-start at initiation of an xrdp session, I can successfully get audio redirects working after running pulseaudio --start or pulseaudio -D in a terminal.

My initial suspicion is that the file permissions on /usr/libexec/pulseaudio-module-xrdp/load_pa_modules.sh and /etc/xdg/autostart/pulseaudio-xrdp.desktop are too restrictive due to the default umask and need to be explicitly placed with 755 on the folders. Otherwise they seemed to be installed fine.

Initial troubleshooting with sudo ls -la /usr/libexec/ output:

-rwxr-xr-x  1 root root  121504 Feb 26 06:11 polkitd
-rwxr-xr-x  1 root root   67968 Mar  5 12:17 power-profiles-daemon
drwxr-x---  2 root root    4096 May 12 23:41 pulseaudio-module-xrdp
-rwxr-xr-x  1 root root   14736 Feb 16 09:20 qmi-proxy
-rwxr-xr-x  1 root root  109024 Feb 17 13:39 rhythmbox-metadata

In an effort to address this, I manually changed the permissions on these:

sudo chmod -R 755 /usr/libexec/pulseaudio-module-xrdp
sudo chmod 755 /etc/xdg/autostart/pulseaudio-xrdp.desktop

I think this might be configurable in https://github.com/neutrinolabs/pulseaudio-module-xrdp/blob/devel/instfiles/Makefile.am? I'm not familiar with makefile.am files, so don't initially know how to set this there.

After manually changing the permissions of these two files, I found that sound over XRDP was automatically starting and working, but only for the user I originally ran the wrapped script from. When logging in with another user, I found I needed to run pulseaudio -D to start up a pulseaudio server. This immediately enabled the redirect to work. I'm not familiar enough with pulseaudio to know what the cause of this may be (yet).

The user configuration files populated (~/.config/pulse/, listed below) seem to be what is missing. Though I don't know what the function is, copying these files from one user to another (and restarting) fixes the issue. Maybe if we could instead replicate this configuration in the system config at /etc/pulse/ it may fix things for all users? At least in an initial skim of this codebase, I'm not sure where this might be configured.

For reference, mainuser is the user the scripts from this repo were run as.

Connection failed: connection denied

Hello to everyone.

I've installed the xrdp client on FreeBSD 13 and the server on Debian Bullseye emulated with bhyve on FreeBSD 13 and then I have followed this guide :

https://github.com/neutrinolabs/pulseaudio-module-xrdp

the installation and configuration of the modules went good,I didn't see any error,but at the end I get the error "connection failed" and I'm not able to understand why. I'm not so expert that I can fix the error only by myself. I'm an hobbist. I'm looking for some help from you. Below I've attached the log of the commands that I have issued...

On freebsd I have connected the xrdp client to the server (installed inside debian with this command)

and then,inside debian I did the following :

https://pastebin.ubuntu.com/p/8fTFtq97rr/

but unfortunately it does not work :

pulse-audio connects to hardware first

I built and installed the module for Kali on arm64. The modules basically work, but there's an issue:
each time I log in via xrdp, at first sound doesn't work, because pulseaudio connects to the device hardware.
After issuing once or twice the commands

pulseaudio -k ; pulseaudio --start

things work just fine. I can't find a good reason for this. Also can't find a forum to ask pulseaudio-module-xrdp specific questions, otherwise I'd have asked there first, before reporting this as an issue.

But I don't know what is wrong. For example:
builddeps:essentials : Depends: build-essential but it is not installable.
If I tried: sudo apt install build-essential then it will annonce me about already installed. (reinstall package i tried too)

Readme file typo

The readme file has the following line:

module-xrdp-sink.la and module-xrdp-source.so may be installed to the target directory, these files are not necessary and you can remove them safely.

Shouldn't that be module-xrdp-source.la instead of module-xrdp-source.so?

How do you remove a failed installation?

I installed this without problems on an Ubuntu 22.04 machine but when i was installing it on an identical machine I accidentally stoped the scripts/install_pulseaudio_sources_apt_wrapper.sh process while it was running and then when i try to run it again i get:

** Remove old build root /var/lib/pa-build/dev before running this script

trying to delete the failed build with sudo rm -rf /var/lib/pa-build/dev returns:

rm: cannot remove '/var/lib/pa-build/dev/sys': Device or resource busy
rm: cannot remove '/var/lib/pa-build/dev/tmp': Device or resource busy
rm: cannot remove '/var/lib/pa-build/dev/home': Device or resource busy
rm: cannot remove '/var/lib/pa-build/dev/proc': Device or resource busy
rm: cannot remove '/var/lib/pa-build/dev/dev': Device or resource busy

When i try to see what process is using it lsof +D /var/lib/pa-build/dev

It returns:

lsof: WARNING: can't stat() fuse.gvfsd-fuse file system /run/user/1000/gvfs
Output information may be incomplete.
lsof: WARNING: can't stat() fuse.portal file system /run/user/1000/doc
Output information may be incomplete.

If i umount those fuse mounts then i get nothing by lsof +D /var/lib/pa-build/dev

I tried to kill the process id i get when i run ps -ef | grep /var/lib/pa-build/dev but it never gets terminated even though it returns a process terminated message. Rebooting, removing and purging everything i installed along pulseaudio doesn't seem to solve the issue.

Does anybody have any recommendations on how to get rid of that failed build?

Thanks in advance for any insights you may have.

Sink and source not detected

I'm trying to follow the build instructions on Debian Bookworm, apt downloaded PulseAudio-15.0+dfsg1

At first I got the same config.h problem as #58, but by copying the file from PulseAudio-15.0+dfsg1/build/config.h to PulseAudio-15.0+dfsg1/config.h I got it to make.

The rest of the instructions worked as-is, and ls $(pkg-config --variable=modlibexecdir libpulse) showed module-xrdp-sink.la module-xrdp-sink.so module-xrdp-source.la module-xrdp-source.so was present.

Problem is, pavumeter shows it's using "Dummy Output".
I checked with pacmd list-sinks and list-sources and the xrdp sink/source isn't visible.

I get:

1 sink(s) available.
  * index: 0
	name: <auto_null>

1 source(s) available.
  * index: 0
	name: <auto_null.monitor>

Am I missing something to configure?

p.s. I'm using the windows Remote Desktop client

No package 'libpulse' found

Hi

I can't get this setup on my Pi with Raspbian Buster - when get to
./bootstrap && ./configure PULSE_DIR=/home/pi/pulseaudio-12.2
I get lots of output that looks OK followed by
checking for LIBPULSE... no
configure: error: Package requirements (libpulse) were not met:

No package 'libpulse' found

Libpulse is installed, if I run
dpkg -l | grep 'libpulse'
then it shows me
ii libpulse0:armhf 12.2-4+deb10u1 armhf PulseAudio client libraries
ii libpulsedsp:armhf 12.2-4+deb10u1 armhf PulseAudio OSS pre-load library

Any ideas?
Thanks

Is there any plan to port this to ALSA or implement MS-RDPEAI?

For my application I would have to use Alsa directly, not Pulse..

Also, are there any plans to implement the Microsoft Client - Server Audio protocol (MS-RDPEAI) ?

Just curious...

sound redirect does not work on gentoo

i can connect to xrdp running on gentoo through xfreerdp: neutrinolabs/xrdp#1796

but the sound redirection does not work even though i added /sound:latency:100 parameter in xfreerdp command.

xrdp works with sound redirection on my ubuntu machine, where i need to use pulseaudio -k to restart the pulseaudio service after sign in through xfreerdp. i use "pactl list modules short" to show pulse modules loaded in xrdp session. i can see that before pulseaudio -k, the module-xrdp-sink is not loaded, and it is loaded after pulseaudio -k.

but on my gentoo system, module-xrdp-sink never load.

i use OpenRC instead of systemd on gentoo, and start xrdp by running xrdp-sesman and xrdp with root in console.

i can see module-xrdp-sink.so in results of "ls $(pkg-config --variable=modlibexecdir libpulse)"

what can be wrong and what shall i check?

UPDATE: i can see "module-xrdp-sink.c: Invalid sample format specification or channel map" error

Error on make: Ubuntu 16.04, pulseaudio version 8.0

I am following the install instructions, and when I get to make, it fails with

there is indeed no config.h only config_ac.h config_ac.h.in and config_ac.h-

any clues / help on diagnosing what went wrong?

focal fossa ubuntu not work with xrdp

Hello!
after git clone --depth=1 https://github.com/neutrinolabs/pulseaudio-module-xrdp
i built successfully as by wiki.

ls $(pkg-config --variable=modlibexecdir libpulse) | grep xrdp
module-xrdp-sink.la
module-xrdp-sink.so
module-xrdp-source.la
module-xrdp-source.so

and no sound in xrdp session
in xrdp.in sound = true
what do have i do?

use pkg-config to determine install target directory

we can get it by:

pkg-config --variable=modlibexecdir libpulse

need version and release

Now the pulse module is provided the separated repository. We suppose distro people provide a package for this module. A version is needed for the package.

Let's make a release after switching to Autotools.

xrdp audio redirection instructions issue

I just got the xrdp audio redirection sink working with the instructions listed here:

https://github.com/neutrinolabs/pulseaudio-module-xrdp/wiki/README

However, following the directions exactly as written did not work. The module that got built following the directions exactly on a fresh centos 7.5 install (after updating all packages) resulted in an audio sink that showed up in the system properties. However, if a bell sound tried to be played from the terminal or testing audio at all, no audio would come through and the entire desktop environment would lock up for about a minute. If multiple bells tried to be sounded from a terminal it would lock up and queue them all it seemed - I got some faint bell sound but after a long delay for each one. So, I removed the .so files from the pulseaudio modules folder.

The instructions should be amended as follows, as this is the procedure that I used to get it to work:

At the step after you clone the repo by default you are on the devel branch, so first checkout master:

git checkout master

Then during the configure stage this will now fail because using only the packages described it did not have the xrdp headers, so:

sudo yum install xrdp-devel

Then the rest of the instructions with running the bootstrap script, configuring, making, and installing worked and resulted in a working audio redirection setup.
