[Solved] Only one sound at a time with Pipewire configured

[nameiwillforget]

I'm aware that soundcards often can only play sound from one application at a time and this often happens to new Gentoo users, but I thought an audio server was supposed to take care of that. I configured Gentoo to use Pipewire, as I did on my previous system Arch, and followed the wiki in setting it up to run a Pulseaudio server, but this one-application problem still happens to me. I did test whether Pipewire was running, and it was, and then I started Wireplumber because I thought it might have some useful output. Here is what it said:

Code: Select all

And it went on to print messages similar to the last. I also tried rebooting because I followed pretty much the same installation procedure on my laptop, and there Pipewire seems to work as it should, but it still doesn't even after the reboot. Any ideas as to the problem?

Check if you have USE pipewire-alsa enabled on media-video/pipewire package, then move away any of your ~/.asoundrc and /etc/asound.conf files and you should be fine. Re-login to desktop environment after these modifications if any were required.

I think the problem was that my user was still in the audio group. It seems solved now.

You do not need to get rid of your .asoundrc (if you have one)
