ehfive/pulseaudio-modules-bt

[Deprecated, see https://github.com/EHfive/pulseaudio-modules-bt/issues/154] Adds Sony LDAC, aptX, aptX HD, AAC codecs (A2DP Audio) support to PulseAudio on Linux

pulseaudio-modules-bt

this repo is a fork of pulseaudio bluetooth modules

and adds LDAC, APTX, APTX-HD, AAC support, extended configuration for SBC

Added Codecs

Codec	Encoding(source role)	Decoding(sink role)	Sample format(s)	Sample frequencies
AAC	✔	✔	s16	8, 11.025, 12,16, 22.05, 24, 32, 44.1, 48, 64, 88.2, 96 khz
APTX	✔	✔	s16	16, 32, 44.1, 48 khz
APTX HD	✔	✔	s24
LDAC	✔	✘	s16,s24,s32,f32	44.1, 48, 88.2, 96 khz

APTX/APTX_HD sample format fixed to s32 in PA. (ffmpeg do the sample format transformation)

Extended SBC configuration

Added support for manual (expert) configuration for SBC codec parameters:

• Min and Max bitpool limits (2-250)
• Sampling frequency
• Audio channel mode
• Quantization bit allocation mode
• Frequency bands number
• Audio blocks number

You can use this parameters to override and fine-tune default SBC codec config and manually setup configurations like SBC XQ, or Dual Channel HD mode. More info about SBC configuration options can be found at LineageOS documentation. Also there is interactive calculator and unofficial device compatibility list that may help you to select proper values.

Parameter-names for module-bluez5-discover and valid values provided at the table below.

NOTE: Use these parameters with caution at your own risk! Invalid or extreme "out-of-spec" configurations may sometimes even cause malfunction for some cheap BT-audio devices. Usually these malfunctions can be fixed by resetting audio-device or sometimes simply by reconnecting with valid configuration.

Usage

Build

backup original pulseaudio bt modules

MODDIR=`pkg-config --variable=modlibexecdir libpulse`

sudo find $MODDIR -regex ".*\(bluez5\|bluetooth\).*\.so" -exec cp {} {}.bak \;

pull sources

Make sure to pull into a filesystem that supports colons (:) as valid characters in filename (see #144). Ext4 does, while NTFS does not.

git clone https://github.com/EHfive/pulseaudio-modules-bt.git
cd pulseaudio-modules-bt
git submodule update --init

install

A. build for PulseAudio releases (e.g., v12.0, v12.2, etc.)

git -C pa/ checkout v`pkg-config libpulse --modversion|sed 's/[^0-9.]*\([0-9.]*\).*/\1/'`

mkdir build && cd build
cmake ..
make
sudo make install

B. or build for PulseAudio git master

git -C pa/ checkout master
mkdir build && cd build
cmake -DFORCE_LARGEST_PA_VERSION=ON ..
make
sudo make install

Cmake A2DP codecs options: CODEC_APTX_FF, CODEC_APTX_HD_FF, CODEC_AAC_FDK, CODEC_LDAC

Load Modules

pulseaudio -k

# if pulseaudio not restart automatically, run
pulseaudio --start

if you got a warning like below, you need to rebuild pulseaudio with --disable-force-preopen flag

pulseaudio: symbol lookup error: pulseaudio: undefined symbol: pa_a2dp_codec_sbc

Connect device

Connect your bluetooth device and switch audio profile to 'A2DP Sink';

If there is only profile 'HSP/HFP' and 'off', disconnect and reconnect your device.

The issue has been fixed in bluez 5.51.

I think thats about it, probally alot more. 

LDAC sample rate won't go up to 96000hz

pacmd list-sinks gives
sample spec: float32le 2ch 44100Hz

According to a previous closed issue, default sample rate was set to 96000hz in this case
; default-sample-format = s16le ; default-sample-rate = 96000 ; alternate-sample-rate = 44100

In addition, default.pa was modified for
load-module module-bluetooth-discover a2dp_config="ldac_eqmid=hq ldac_fmt=f32"

Clementine music player was used and output sample rate was also set to 96000hz.
Why? So confused!

PPA Ubuntu Disco Support

Ubuntu 19.04 (disco) is released next week, any chance the PPA can be updated?

Dropping connection

I lose connection spontaneously. I think the problem is coming from dbus

[system] Rejected send message, 3 matched rules; type="method_return", sender=":1.25" (uid=112 pid=1724 comm="/usr/bin/pulseaudio --system --disallow-exit --dis") interface="(unset)" member="(unset)" error name="(unset)" requested_reply="0" destination=":1.3" (uid=0 pid=384 comm="/usr/lib/bluetooth/bluetoothd ")

Running
dpkg -l dbus
Returns

dbus 1.10.26-0+deb9u1 armhf

Any thoughts?

Can't get aptx or aptx_hd sinks to be available

Hello.

I am under Fedora and I updated to the 1.1.3 rpm packages you provided (#20) which provides handy looking profiles.

The only sad part is that... I can't get my device (which is a Plantronics Backeat Pro 2) to get detected as a aptx enabled device as shown on the output below:

Card #3
	Name: bluez_card.E4_22_A5_BD_10_A9

		bluez.path = "/org/bluez/hci0/dev_E4_22_A5_BD_10_A9"
		bluez.class = "0x240404"
		bluez.alias = "PLT BB PRO 2"
		device.icon_name = "audio-headset-bluetooth"
		device.intended_roles = "phone"
	Profiles:

		headset-output: Headset (priority: 0, latency offset: 0 usec)
			Part of profile(s): headset_head_unit, a2dp_sink_sbc, a2dp_sink_aac, a2dp_sink_aptx, a2dp_sink_aptx_hd, a2dp_sink_ldac
		headset-input: Headset (priority: 0, latency offset: 0 usec)
			Part of profile(s): headset_head_unit

I am nonetheless sure that it worked at some point with the previous package under Aptx.

Some audio package updated afterwards, and I had huge audio artifacts, removed the older version and tried the new version install (which obviously worked with the sink separations.

I tried un-pairing, repairing, unconneting, reconneting and so on, couldn't get the availability to pop up.

Any hint or known issue?

Attempting to switch to an unsupported codec breaks all A2DP profiles until bluetooth device is reconnected

1. Connect to a device

5. At this point, if I try to play something via this sink, it hangs.

   $ pactl set-card-profile bluez_card.30_C0_1B_8D_9C_F1 a2dp_sink_sbc
   Failure: Input/Output error
   

7. This is where things go wrong. The sink disappears and does not reappear until the device is reconnected.

   $ pactl list sinks
   <...> (only irrelevant sinks here now)
   

8. Try to switch to HFP/HSP profile (it actually works)

   $ pactl set-card-profile bluez_card.30_C0_1B_8D_9C_F1 headset_head_unit
   

9. Observe the sink again

AAC encoding error

First of all, thank you for this project! I didn't think I'd ever be able to use bluetooth headphones on Linux before finding this.

Everything seems to be working correctly (with pactl showing the AAC codec in use), but after a certain amount of time (sometimes minutes, sometimes seconds), the pulseaudio output device automatically switches back to the default (line out) and journalctl shows the following error:

pulseaudio[22152]: E: [bluetooth] a2dp_aac.c: AAC encoding error, 0x60

I can then switch the output device back to the bluetooth headphones and it'll work again for a few more seconds or minutes until the error appears again. I tried manually switching the output away from the bluetooth headphones to see if the error was triggered in the other direction, but no error messages appear in that case. The bluetooth logs don't show any brief disconnects or anything either.

Let me know if there's any additional output or tests I can perform to help!

Xiaomi AirDots Pro: AAC codec not recognized

Good morning,
i've some problem to make these (english version) earbuds working with AAC audio codec.
According to their specs, AAC is supported: in fact i'm able to make them working with some devices (e.g. Nvidia shield / Oneplus 3... the funniest thing is that they are not working with Xiaomi phones but this is another story).
avinfo doesn't recognize any 2nd sink profile (no unknown profile is listed)
I've attached some logs
Any hints?
Thanks in advance

1. Report success with my Sennheiser HD1 + XPS 15:

                bluez.alias = "HD1 M2 AEBT"

2. Ask if there is a way to make the selected codec expressed somehow in the UI, specifically as the HD1 headphones, for example, in what I presume is not their singular problem, fails to show which codec is being used...:

aptX LL support

Any plan to support aptX LL (Low Latency) mode?

Can not connect to LDAC device

Device: Sony Walkman ZX300A With Bluetooth DAC Mode

Post your patches to Pulseaudio maillist

Hi, there's a patch on Pulseaudio maillist for the modular A2DP API: https://lists.freedesktop.org/archives/pulseaudio-discuss/2018-July/030344.html
Support for aptX: https://lists.freedesktop.org/archives/pulseaudio-discuss/2018-July/030344.html
And a discussion regarding using gstreamer or ffmpeg for additional codecs: https://lists.freedesktop.org/archives/pulseaudio-discuss/2018-July/030201.html

It would be great if you can negotiate the best method of LDAC integration with Pulseaudio developers and commit it directly to the main branch.

Loading soversion-less libraries

See #20 and by @devurandom this comment for LDAC, plus see this bug report for libavcodec.

Essentially, at runtime the package should require the same major soname version that it was compiled with, since soversion-less files are only in -devel packages, at least this is the standard for Fedora, and also Debian.

Sound artifacts/cracking with aptX which started some time after the installation

Hello,
Thank you for your great work, really appreciate it.
My setup is Dell E7440 with Intel 7260, Kubuntu 18.04, Sennheiser M2 AEBT with aptX.
The modules were installed from the deb package.

At the beginning everything was great, I had no issues.
Some weeks later heavy cracking while listening started.
Calling pulseaudio -k fixes it, but I think it also messes up with the sound quality. Is it possible that after the aptX is no longer used?

piter@piter:~$ pactl list sinks | grep -e bluez -e a2dp_codec
	Name: bluez_sink.00_1B_66_84_1D_AF.a2dp_sink
	Driver: module-bluez5-device.c
	Monitor Source: bluez_sink.00_1B_66_84_1D_AF.a2dp_sink.monitor
		bluetooth.a2dp_codec = "aptX"
		device.api = "bluez"
		bluez.path = "/org/bluez/hci0/dev_00_1B_66_84_1D_AF"
		bluez.class = "0x240404"
		bluez.alias = "MOMENTUM M2 AEBT"
piter@piter:~$ pulseaudio -k
piter@piter:~$ pactl list sinks | grep -e bluez -e a2dp_codec
	Name: bluez_sink.00_1B_66_84_1D_AF.headset_head_unit
	Driver: module-bluez5-device.c
	Monitor Source: bluez_sink.00_1B_66_84_1D_AF.headset_head_unit.monitor
		device.api = "bluez"
		bluez.path = "/org/bluez/hci0/dev_00_1B_66_84_1D_AF"
		bluez.class = "0x240404"
		bluez.alias = "MOMENTUM M2 AEBT"

At the first glance it may seem like a bandwidth or link quality issue, but there are some points that make me think this is not the case:

1. Everything is fine when I use the mobile phone (also with aptX) in the same environment, I can even be at a significant distance from the phone and everything is fine.
2. Headphones are really close to the PC.
3. Nothing in the environment changed, at the beginning it was fine.

After the issue has been observed I tried things like:

1. Installing the package again,
2. Compiling it from the source.
3. Setting an option MultiProfile = multiple in /etc/bluetooth/main.conf seemed to work for a day, but the issue reoccurred.
4. Manually switching output source back and forth sometimes used to fix it for a short time, but now it does not do the job.
5. After pulseaudio -k there are no cracks, but executing it every headphones connection is a pain and I think that sound quality decreases as well.

As I have no idea what additional information I could share please find some random logs below ;)

I messed a lot with the bt/modules maybe I should clean the BT and pulseaudio modules installation?
How can I do it to be sure that the setup is as good as it can be?

Any hints are very welcome!

Kind regards,
Piotr

[VOTE] Should we merge branch `ldac-slice-rc`?

I have pushed 0119afd to branch ldac-slice-rc;
Please tell me is that commit improves the ability to handle sound cracking under LDAC ABR mode?

High Latency due to forced LDAC?

Is there a way to force aptX Low Latency given that quality isn't the only discerning factor in these standards or has aptX LL not been reverse engineered? Or would the latency difference be negligible

Note that the SBC profile is "available: no":

I think this is wrong because these headphones work with stock PulseAudio (which presumably does not support any of the advanced codecs).

pactl list sinks | grep -e bluez -e a2dp_codec Name: bluez_sink.04_5D_4B_DE_B9_93.a2dp_sink Driver: module-bluez5-device.c Monitor Source: bluez_sink.04_5D_4B_DE_B9_93.a2dp_sink.monitor bluetooth.a2dp_codec = "APTX_HD" device.api = "bluez" bluez.path = "/org/bluez/hci0/dev_04_5D_4B_DE_B9_93" bluez.class = "0x240404" bluez.alias = "WH-1000XM2"

Seems weird to me as it should automatically detect LDAC is enabled properly. I have libldac installed through the AUR, and it works on my phone.

Is there a config option to force AAC codec?

I had an early preview of this module installed on Fedora 29 and noticed that my AKG-Y50BT was connecting using AAC codec instead of AptX as I expected.
After updating to Fedora 30 headphones begin constantly connecting via AptX codec. And surprisingly I found myself preferring AAC more.

Is there a config option to "force" AAC? I did changed bluetooth.service as WIKI describing, but don't see AAC in KDE profiles selection window.

GPL is incompatible with FDK-AAC - redistribution permission needed for Fedora/RPMFusion

See this:

FSF issued a clear statement that the fdk-aac is GPL incompatible
https://www.gnu.org/licenses/license-list.en.html#fdk
Can you clarify with upstream about this ?
Please ask upstream to send an email to explicitly allow us to redistribute
the software when built with fdk-aac.
Please send the email at [email protected] from an upstream maintainer (using public maillist list).
The email will be added to the scm if allowed.
Thx in advances.

2 issues:

• GPL incompatibility, see here, and for fdk-aac-free, here
• From your public email, please send an email to the above address, cc me, too (gombosg at gmail dotcom)

e.g.

I, xx, upstream developer of the pulseaudio-modules-bluetooth-freeworld package explicitly allow RPMFusion to redistribute the software when built with fdk-aac libraries.

Thanks!

Building on Fedora 29

pkg-config libpulse --modversion returns 12.2-rebootstrapped
This causes a linker error because the actual lib is just /usr/lib/pulseaudio/libpulsecommon-12.2.so, but gcc wants to link -lpulsecommon-12.2-rebootstrapped

AAC passthrough?

I wonder if it's possible / doable / desirable to support some sort of AAC passthrough via PA's compressed stream passthrough feature, so that reencoding could be skipped if one plays an AAC-encoded stream on a bluetooth device that supports AAC natively?

glitches or crackling

It's better to separate processes to multiple threads, and store encoded data with queue instead of transport data after encoding immediately.

crackling sound / bandwith problem?

hi! first of all thank you, its awesome to have ldac on my notebook!

not 100% sure if this is an actual issue or my hardware is just crap ( i tried with usb bluetooth chips too though):

especially when using ldac_eqmid=hq i get a lot of crackling, probably a bandwith problem.
even if i rfkill block the wifi ( Intel Dual Band Wireless-AC 8265 ).

my questions:

• is there a way to get more debug information, i.e. what quality is actually being used if ldac_eqmid=abr is set ?
• is there other options to tune the bt stack e.g. adding more buffer ? (on os-x you can tune the buffers)
• do the pulseaudio settings such as default-sample-format default-sample-rate and resample-method influence LDAC playback ?

Just wanted to thank you

Also don't worry about the poor English, it's not as important as amazing code and features like yours :)

Disable some profiles

My android phone starting play as SBC, then immediately switch to the aptX HD. I've tried to select LDAC through developer options seems no Bluetooth setting in there affect anything (nor bitrate nothing). But even if it did, there is no way to save selected profile, this option is temporary, for debugging purposes.
I am using loud expensive speakers with dolby digital plus audio card, and I would like to play from my phone wireless. aptX HD is not good enough, I clearly hear distortions. Its still "fine" though.

So, could i "hide" blueZ support of aptX codec for example? Or show it with a huge delay?

Ideal flow for devices with no LDAC support:

Connecting
Playing as SBC
Got the support of LDAC
Still playing as SBC
Got the support of aptX
Switching there as it preferable by Android ROM

Ideal flow for devices with LDAC support:

Connecting
Playing as SBC
Got the support of LDAC
Switching to LDAC there as it preferable by Android ROM
Got the support of aptX (or if it possible don't get data about it at all)
Still playing as LDAC cause they considered similar

I've read https://github.com/EHfive/pulseaudio-modules-bt/wiki#can-i-choose-codec-
But my OnePlus 5T with Android 8.1 has built-in LDAC support, and it still:

pactl list sources | grep -e bluez -e a2dp_codec

		bluez.class = "0x5a020c"
		bluez.alias = "xxx"

Autoconnected device won't switch to A2DP sink profile

Thank you for this fantastic project first of all! It works great! However there's a small issue with bluetooth auto connect.

To be more elaborative, if I turn off my headphone while connected to a computer, and then turn the headphone back on again, the headphone will automatically reconnect, but in a low quality mono channel 8kHz mode. However, this can be easily fixed by simply disconnect and reconnect again (from the computer using commands like echo disconnect <MAC> | bluetoothctl; echo connect <MAC> | bluetoothctl). After the reconnection it will be in LDAC mode as expected.

I'm not familiar with pulseaudio or bluetooth, so this might be a trivial question, but I searched the Internet and find no useful information to this situation.

Trying to package for Fedora 29

Hi, I'd like to make a COPR repo for this in Fedora since aptX is working great when building with your instructions.
I only want to upload the pulseaudio-module-bluetooth to the repo and not the whole PA to avoid issues - PA is an important package.
I tried the patch the current PA source SRPM package with your patches for the best system compatibility.

I applied them in order:

%patch901 -p1 -b _v1_1.a2dp
%patch902 -p1 -b _v1_2.a2dp_property
%patch903 -p1 -b _v1_3.ldac_header
%patch905 -p1 -b _v1_5.fix_ldac_frequencies
%patch906 -p1 -b _v2.1_1.aptx_aptx_hd_fix
%patch907 -p1 -F2 -b _v2.1_2.buildfile

They applied fine, but build fails with

modules/bluetooth/a2dp/a2dp_aptx.c:5:10: fatal error: libavcodec/avcodec.h: No such file or directory
 #include <libavcodec/avcodec.h>

It finds libavcodec during the configure phase:

checking for FF_AVCODEC... yes
checking for FF_AVUTIL... yes

And yet it fails.
I know I should contact the packager maybe but maybe you know why this fails or at least point me to the right direction why make doesn't find this folder (e.g. by adding the correct -I parameter).

Here's the complete build log with the error at the end:
build.log

Here's my modified RPM spec file:
pulseaudio.spec.txt
At line 335 you can see the configure parameters, maybe those are the culprit.

It would be my first package ever so I don't have much experience so I appreciate the help.

Enable AAC afterburner by default ?

Hello,

Since the AAC support is done through the Fraunhofer FDK AAC library, I've had a look at their wiki and they recommend to always enable the afterburner feature since it brings better quality (at the expense of more processing power required). However, the current implementation here disables it by defaut, so my question is shouldn't it be enabled instead ?

My source is: https://wiki.hydrogenaud.io/index.php?title=Fraunhofer_FDK_AAC#Afterburner

Thanks ! :)

Submit pulseaudio-modules-bt to Fedora/RPMFusion

Hi, I created this COPR (user) repo for the package:
https://copr.fedorainfracloud.org/coprs/gombosg/pulseaudio-modules-bt-aptx/

I repackaged the original Fedora Pulseaudio source with your patches. It works for me™, hopefully people can test it this way. Please add it to the wiki.

patches don't apply

could you please release just one single (and complete) patch against pulsaudio-12.2 or so?
or even better: fork the pulseaudio repo and apply your changes to an extra branch, having a own build system and overwriting files on a users system isn't a good way to go, anyway

besides from that, love your work :)

AAC is not automatically selected on my AAC/SBC headphone

My system if Fedora 29 with pulseaudio-modules-bt installed from the COPR repo, fdk-aac and ffmpeg installed from RPMFusion. I already reloaded pulseaudio. Is there something else that I should do to get this to work?

Resume crashes on Manjaro

I installed this repo on Manjaro via https://aur.archlinux.org/packages/pulseaudio-modules-bt-git/ but I've found out that resuming from suspend basically dies. As soon as the laptop is woken up it is restarted - the title might be misleading but I didn't know how to describe the problem in few words.

There is nothing in the journal and I've been trying 4.18 and also 4.14.
I had to uninstall it and since then I can resume my laptop again.

Include Ubuntu 16.04 in the package

I had a tough time building the package on Ubuntu 16.04.5. Any chance this version could be added to the PPA? I'd love to use this!
Thanks

Check if bluetooth device supports LDAC/aptX HD/aptX/AAC and details

I'm on Debian testing and before I mess around trying to get Ubuntu PPA working on Debian, is there anyway to verify that my device supports those codecs in the first place?

$ pactl list | grep codec
$ pulseaudio --version
pulseaudio 12.2

There doesn't seem to be any codec entry in the output of pactl list. Is there any prods I can use to poke at my headset and find out what codecs it supports?

PS Idol animes are trash.

Add HFP support ?

Over at https://git.kernel.org/pub/scm/linux/kernel/git/jejb/pulseaudio.git/log/?h=jejb-v12
there are patches for HFP support so that headset with HFP only profile will

into here so one can use such headsets with these new codes

Building DEB package

I've managed to get a working DEB package by building the binary as described (cmake .. && make).
Since I really hope this will be merged to the original PulseAudio (and, consequently will end up in repositories sooner or later), I did not bother with fancy stuff and using CPack.

However, I wanted to share my script for re-building pulseaudio-module-bluetooth using binaries build from these sources and the original DEB shenanigans from (Ubuntu/Debian) repository.

Doesn't build with fdk-aac 2.0

Latest 'Rawhide' version of Fedora comes with fdk-aac 2.0. Build fails with that since the build dependency is simply fdk-aac>=0.1.5 and 2.0 is accepted this way. Probably other distros will upgrade soon, as well.

Is it possible to add 2.0 support? (I know it's probably a breaking release.)

I have attached a build log.
build.log

Basically it's:

-- Checking for module 'fdk-aac>=0.1.5'
--   Found fdk-aac, version 2.0.0

but

BUILDSTDERR: /usr/bin/ld: cannot find -lfdk-aac

Here's the fdk-aac-devel-2.0 package info and here are all the new fdk-aac packages.

Let me know if this is a Fedora packaging issue, but the 2.0 update was as simple as a version bump. (Which only modified the source URL, with the same build config)

Thanks!

That's what I see in pulseaudio -vvv, a lot of messages like this (500+ lines).
When it's happening there is no sound at all from the phone.
It's became very randomly, you can listen to music 5-30 minutes and then no sound after changing songs or closing currently playing player at the phone. It will stop output errors only if you pause or closing current playing song or player. After it stops output errors music playing perfectly.

My setup:
linux: Archlinux
laptop: linux-lts (4.19.31-1), ffmpeg (1:4.1.2-1), pulseaudio (12.2-2 , 2channels - 24bit - 48000Hz),
raspberry pi: almost the same setup.
phone: Xiaomi Redmi 5 Plus, RR 7.0.1 + installed aptX libs
Tried with only one phone , haven't any other device supporting aptX.

Have tried with hardware solution CSRA64215, it's working without any issue.
Just curious if there is something wrong with my setup that's preventing sync for aptX.

P.S. Thanks a lot for this modules.

Thank you, StS.
