Playing around a bit.

After killing these programs:

Code:

$ systemctl --user stop pipewire wireplumber pipewire-pulse
$ ps aux | grep -i -e pipe -e wire
myusername 23068 0.0 0.0 9148 2432 pts/1 S+ 00:32 0:00 grep --color=auto -i -e pipe -e wire

...all audio on my laptop stops functioning except Parsec, which continues to play through my internal laptop speakers, which I'd guess means is working in a way that bypasses the need for any of those programs. I can't find another program that seems to handle it but it's possible I'm not finding it because its called something generic that doesn't stand out as an audio program.

Looking at pw-cli and pactl, which I'm not the greatest at:
- I'm not seeing anything about parsec
- I believe I see my built-in speakers? I see built-in something. I broke it and am seeing less since stopping those processes so I'll edit after a reboot.
Edit: I was seeing the built-in audio input so that would be the microphone.

Code:

$ pactl list sources | grep -i -e 'name:'
Name: alsa_input.pci-0000_00_1f.3.analog-stereo
Name: alsa_input.usb-BLUE_MICROPHONE_Blue_Snowball_201305-00.pro-input-0
Name: bluez_output.00_0A_45_19_F0_E4.1.monitor
$ pactl list source-outputs | grep -i -e 'name:'
$ pactl list sinks | grep -i -e 'name:'
Name: bluez_output.00_0A_45_19_F0_E4.1
$ pactl list sink-inputs | grep -i -e 'name:'
module-stream-restore.id = "sink-input-by-application-name:Firefox"

I installed qpwgrap to get a visual representation of my pipes to aid with the CLI commands, and I notice a few things. Photo here: https://imgur.com/a/GE4rk8U
- Parsec program never shows up even when audio is playing through the speakers
- Firefox shows it has outputs
--- if i play a video or something, i can see it connect to my headphones input
- My working bluetooth headphones have inputs and outputs
--- the headphones have a microphone, I presume that's what im seeing as output
--- The built-in audio shows up, but only has outputs and no inputs
- if i use qpwgraph to connect the built-in audio output to my headphones input, I can hear myself, so that with the hint from my headphones I assume is the microphone

Try moving/deleting ~/.local/state/wireplumber
and restarting wireplumber:
systemctl --user restart wireplumber*.service

(or log out and back in)
This *should* reset audio back to defaults. It is possible you *might* also want to unpair and re-pair Bt audio devices, just to make sure everything is "clean".

. Why is Parsec playing through my speakers and not being seen by the GUI (settings/widget) nor respecting default audio?

That would be a question for the Parsec folks, methkinks.

Hey claydoh, thanks for the help. That did give me my internal audio speaker device back. Thanks a lot.

I totally agree.

Tonight my goal for myself is to figure out how it's working at all - how audio works in the absence of pulse/alsa/pipewire/etc.. I think that will help me determine the remainder of the issue.

My speakers disappeared when I go to applet, select the burger menu, and change from 'Analog Stereo Duplex' to 'Analog Stereo Output'. I don't know what that setting does but it requires I delete that file in the folder to see it in any GUI again.

On the parsec/alsa/pipewire front:

Looks like if i install libasound2-plugins, I get an /etc/alsa folder and audio changes after restarting parsec - it goes completely muted.

sudo apt install libasound2-plugins

I read somewhere that someone on Fedora 34 had an issue with parsec until they deleted /etc/alsa/conf.d/99-pulseaudio-default.conf, but I don't have that file. I tried deleting /etc/alsa/conf.d/50-pulseaudio.conf and the audio went back to playing through my speakers. Whatever I have to do, it must be in relation to that file.

Code:

username@rat:~$ cat /etc/alsa/conf.d/50-pulseaudio.conf
# Add a specific named PulseAudio pcm and ctl (typically useful for testing)

pcm.pulse {
        @args [ DEVICE ]
        @args.DEVICE {
                type string
                default ""
        }
        type pulse
        device $DEVICE
        hint {
                show {
                        @func refer
                        name defaults.namehint.basic
                }
                description "PulseAudio Sound Server"
        }
}

ctl.pulse {
        @args [ DEVICE ]
        @args.DEVICE {
                type string
                default ""
        }
        type pulse
        device $DEVICE
}

After some playing around I narrowed things down to installing this package:
sudo apt install pipewire-alsa

Contents:

Code:

username@rat:~$ dpkg -L pipewire-alsa
/.
/etc
/etc/alsa
/etc/alsa/conf.d
/usr
/usr/lib
/usr/lib/x86_64-linux-gnu
/usr/lib/x86_64-linux-gnu/alsa-lib
/usr/lib/x86_64-linux-gnu/alsa-lib/libasound_module_ctl_pipewire.so
/usr/lib/x86_64-linux-gnu/alsa-lib/libasound_module_pcm_pipewire.so
/usr/share
/usr/share/alsa
/usr/share/alsa/alsa.conf.d
/usr/share/alsa/alsa.conf.d/50-pipewire.conf
/usr/share/alsa/alsa.conf.d/99-pipewire-default.conf
/usr/share/doc
/usr/share/doc/pipewire-alsa
/usr/share/doc/pipewire-alsa/copyright
/etc/alsa/conf.d/50-pipewire.conf
/etc/alsa/conf.d/99-pipewire-default.conf
/usr/share/doc/pipewire-alsa/changelog.Debian.gz

Then messing with this file seems to break it completely.
/etc/alsa/conf.d/99-pipewire-default.conf

My parsec now outputs with the rest of my audio.
