ncpamixer's Issues

Show volume levels also in dB

Knowing the value also in dB, alongside the percentage, would be great!

Instead of just showing the percentage, maybe something like this: (-12.04 dB — 65%)

make error: undefined reference to symbol 'keypad'

Hey, I've tried makeing this from both the supplied Gentoo fulhax overlay through Portage, as well as by cloning the git repo, cding in and running make. Using both methods I end up getting the error below:

[100%] Linking CXX executable ncpamixer
/usr/lib/gcc/x86_64-pc-linux-gnu/7.3.0/../../../../x86_64-pc-linux-gnu/bin/ld: CMakeFiles/ncpamixer.dir/ui/ui.cpp.o: undefined reference to symbol 'keypad'

I'm not sure if it's an issue on my end, maybe with ncurses or cmake, as I'm quite new to the whole Linux thing. For reference, I am running
Gentoo kernel 4.14.61, PulseAudio 12.2, ncurses 5.9-r101 & ncurses 6.1-r2, and cmake 3.12.1.

Again I'm not sure if this is an issue with my personal system or with ncpamixer.

ncpamixer crashes when module-loopback is loaded

The title says it all (at least, all I could tell): when module-loopback is loaded, ncpamixer crashes. If you unload the module, it starts, but would crash once you have loaded it again.

Glyphs not rendering correctly

I'm running Linux archlinux 5.4.13-arch1-1 #1 SMP PREEMPT Fri, 17 Jan 2020 23:09:54 +0000 x86_64 GNU/Linux and

ncpamixer v1.3
Build type: release
Build date: 2020-01-20 16:59

The three fonts shown are Monofur, Monaco and Hermit. As you can see, instead of the little symbol() the ~Y is displayed. Also the slider is not displayed as it should be, but instead there is a VH:

With some other fonts the glyphs are rendered correctly, but since Hermit is the one I mainly use I'd like to know whether it's possible to fix this in some way?

[Request] Distracting free static view

It would be nice with a toggable static view that's not distracting when you leave it open. Like this:

Add detailed instructions to compile.

Please add detailed instructions about the compilation of ncpamixer in the README.md. I'm getting some errors when i try to compile it in my laptop with ubuntu, but i'm not sure if i did it correctly.

Segfault when used in combination with "noise-suppression-for-voice"

I recently installed and configured werrman's noise-suppression-for-voice plugin. However, after the setup, ncpamixer immediately segfaults when trying to launch it.

Could this be related to #43 , i.e. could it be because the new sinks don't have a description or something like that?

Left-right channels manipulation

Is there a way in ncpamixer to change the volume for left or right channels on devices independently?
I see nothing in dropdown menus and in general man pages, too.
Would be great to add this ability, by the way, it is implemented in pavucontrol, if I'm not mistaken.

Editing the CMakeLists.txt file to use hard coded values instead of the "found ones", the compilation works fine.

SIGSEGV When selecting new track in VLC

pipewire-pulse: 0.3.44-r1/~amd64
ncpamixer: 1.3.3.1/~amd64
wireplumber: 0.4.7-r1/~amd64
vlc: 3.0.16-r7/amd64
Gentoo x86_64 nomultilib/systemd

When using this combination with a playlist of FLAC and MP3 files, ncpamixer crashes with a SIGSEGV upon selecting a new track. From what I can observe in pavucontrol, VLC destroys its connection to pulseaudio and recreates it whenever a new track is selected, which seems to crash ncpamixer. It does not crash pamix, however neither are able to smoothly display VLC's level bars, indicating maybe some sort of sample rate inconsistency. My FLAC files are standard 48khz, and my MP3s are mostly 384kbps 44.1khz. I unfortunately can't share any sample files, but some of them can be downloaded from Bungie's website for free if you have trouble reproducing this.

I can also try building as debug, but I don't have much experience with gdb and probably wouldn't be able to make much in the way of a useful stacktrace.

ncpamixer segfaults when using non-existing "--help" parameter

I was just testing ncpamixer and was greeted with a segmentation fault when I ran it for the first time. I usually do run a ${command} --help for any new software, just to see how to run the software properly.

sven /portage > ncpamixer --help
zsh: segmentation fault  ncpamixer --help
sven /portage > ncpamixer -h    
ncpamixer: invalid option -- 'h'
(the command above starts ncpamixer)
sven /portage > ncpamixer -v
ncpamixer v
Build type: gentoo

sven /portage > ncpamixer --version

Build type: gentoo
Build date: 2016-08-17 13:23

I guess there is a minor bug in the use of getopt_long() and its longOpts parameter. The man page states:

The last element of the array has to be filled with zeros.

And the example has the following definition:

        static struct option long_options[] = {
            {"add",     required_argument, 0,  0 },
            {"append",  no_argument,       0,  0 },
            {"delete",  required_argument, 0,  0 },
            {"verbose", no_argument,       0,  0 },
            {"create",  required_argument, 0, 'c'},
            {"file",    required_argument, 0,  0 },
            {0,         0,                 0,  0 }
        };

I wrote a small patch which fixes the segmentation fault, and I'm going to create a pull request.

Reconnect to PulseAudio

Reconnect to PulseAudio on restart or connect to PulseAudio if it's started after ncpamixer.

Crash when device.description not defined

Hi,

I had a source output configured where the property device.description was not defined. As a result pa_proplist_gets returns a null pointer in the following line which made ncpamixer crash at startup.

ncpamixer/src/pa.cpp

Line 300 in 8ab3a86

p->app_name = pa_proplist_gets(info->proplist, PA_PROP_APPLICATION_NAME);

NCPAMIXER controls not working on Manjaro i3

I'm running Manjaro i3 20.0.1. I installed pulseaudio and pavucontrol, which are working. But then, I saw a video about ncpamixer and installed it through AUR. Cloned the repository into my /tmp/ folder and used makepkg -si to install it. The only keybind working was L and H to navigate through tabs, nothing else.

new tag release

it seems 30aa766 (aug 2021) has fixed a segmentation fault (#58) i had with ncpamixer.
last release was in sep 2020.

Allow user to select input/output device

Maybe I missed something but I can't find a keybinding to select a input/output source. I had to run the commands:

pacmd list-sink-inputs
pacmd move-sink-input [input index] [sink index]

to switch between different output devices for example.

Pseudographics is shown as letters

Volume can go up to infinity

Not sure if it's by design, since in many clients it's limited to 150-153%.

But apparently I can go above 2000% with ncpamixer 🙂

Segfault after navigating up in Configuration

Version: 1.3.3

Steps to reproduce:

1. Go to Configuration
2. Use ↑ to navigate beyond the top element

Startup tab flag

It'd be nice to have some flag -t to start ncpamixer on a specific tab.

e.g. ncpamixer -t input would bring you to Input Devices on startup.

Makefile issue

If I compile using make on the Makefile, I get a program that responds to F* keys, q and ESC, but no other keys seems to work. If I compile with cmake, everything works fine.

Seems like a weird bug. Could it be a debug setting in the Makefile or something?

Two tabs on one?

Somewhat like https://github.com/rafalcieslak/pavucontrol?

UI issue on Ubuntu Bionic

First off, really cool project!

It works very well on my Arch install, but seems to have character-drawing problems on Ubuntu. Maybe specific to my setup, but I spent a few minutes looking at the code and my environment and didn't see anything obviously wrong.

Here's what I see shelled into my Ubuntu machine:

Output from locale seems reasonable:

➜ locale
LANG=en_US.UTF-8
LANGUAGE=
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"

LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"

LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=

I also thought maybe it was some sort of Unicode character drawing issue, but I tried another terminal-based app and it seems to be rendering extended (non-Latin, UTF8) characters just fine.

For reference, here's what it looks like when I'm shelled into my Arch install:

1.3.3.1 and master segfault, 1.3.3 is fine

with 1.3.3.1 or current master branch I just briefly see a message:

and then:
Segmentation fault (core dumped)

on 1.3.3 this does not happen, however I don't see the correct terminal fonts for the gui (as mentioned in #46 ).

Missing fonts?

Are fonts missing?
What are required fonts?

Any ideas?

WIP: OSX Version

By wrapping pulseaudio in the new Audio class we should be able to implement other sound engines. I will try to implement Core Audio for osx.

Add keyname mappings to config

Implement a way to transform keycode.[modifier].[keyname] to keycode.[keycode] when reading config.

Build error: ‘BUTTON5_PRESSED’ was not declared in this scope

When I try to build ncpamixer on Ubuntu 18.04, I get this error:

ncpamixer/src/ui/ui.cpp: In member function ‘void Ui::handleInput()’:
ncpamixer/src/ui/ui.cpp:277:44: error: ‘BUTTON5_PRESSED’ was not declared in this scope
                 } else if (mevent.bstate & BUTTON5_PRESSED) {
                                            ^~~~~~~~~~~~~~~
ncpamixer/src/ui/ui.cpp:277:44: note: suggested alternative: ‘BUTTON1_PRESSED’
                 } else if (mevent.bstate & BUTTON5_PRESSED) {
                                            ^~~~~~~~~~~~~~~
                                            BUTTON1_PRESSED

I have these packages installed:

• libpulse0
• libpulse-dev
• libncurses5
• libncurses5-dev

No idea what else could be missing.

Option to disable live vu-meter feature

I really like the vu-meter like pavucontrol does, but I'm that kind of guy who keep that stuff running h24 and it eats ~5% cpu all time.
I guess it's related to the runtime sampling for monitoring the volume per source. Original pavucontrol have the same behavior.

I think, if we can disable the vu-meter feature and just listening for event, it could reduce cpu usage to about nothing. I didn't checked the code yet, I'll take a look when I'll have time and prepare a pull request if possible.

Help dialog

Suggestion: ? key should open a help dialog, listing the keyboard shortcuts. ncdu behaves this way.

ncpamixer fails at runtime:

W: [(null)] caps.c: Normally all extra capabilities would be dropped now, but that's impossible because PulseAudio was built without capabilities support.

Pressing F1-F4 causes ncpamixer to exit

Pressing F1-F4 cuases ncpamixer to exit and it's not possible to change tabs with these keys. I can change tabs using H and L key bindings. The exit code is 0.
I built ncpamixer today using aur/ncpamixer-git

Events to set volume level

Add new events for setting levels at certain percent.

For example:
set_volume_10 sets volume to 10%
