Audio does not work in KDE #267

Closed vincent-163 closed 1 year ago

vincent-163 commented 1 year ago

Here is /var/log/neko/pulseaudio.log: [pulseaudio.log](https://github.com/m1k1o/neko/files/11072189/pulseaudio.log) The log looks perfectly normal, and audio is working in firefox, not sure why it doesn't work in KDE (no devices are visible). I tried creating virtual sinks via pacmd load-module module-null-sink sink_name=MySink but I got Daemon not responding.. Any ideas on how to get audio working on KDE?

Despite it being hidden from KDE control panel and only shown as inactive, it works. image

Tried multiple applications and even volume changing works. image

It looks like the default pulseaudio sink auto_null is intentionally ignored by KDE. Renaming audio sink fixes this issue.

Thanks for the update. I tried out the latest image m1k1o/neko:kde after the update but things have not changed: photo There are no audio devices shown before and after the update.

The host operating system is a fresh Ubuntu 22.04 Server (no gui installed) on Hetzner Cloud in case that matters. It also has cap_add: - SYS_ADMIN in order to enable Chrome. The other tested image was Firefox, where audio does work.

Sorry, I forgot to mention that I also mounted an empty directory with owner 1000:1000 to /home/neko inside the container. It seems that an empty directory lacked the configuration needed to get audio working, and that was the actual reason. Sorry for the disruption.

Glad it works. Yes, it is missing ~/.config/pulse/client.conf file, that should contain default-server=unix:/tmp/pulseaudio.socket. Maybe there is some way how to get rid of this dependency and allow users mounting whole home directory in the future.

According to their documentation, adding env PULSE_SERVER=unix:/tmp/pulseaudio.socket should fix the problem and remove the need for client.conf.

In my case, using KMix instead of plasma-pa is one way to fix it.
