I upgraded to Fedora 35 two days ago. At first, everything seemed to be working fine. But suddenly I had sound (and video) problems. Video was playing every 20 seconds one frame, audio not at all. After restarting everything seemed to be fine.
But at some point, not even rebooting solved the issue. So I tried
systemctl --user enable --now wireplumber.
This solved the issue at first but not for long. Anyway, I did a lot of different things, like:
sudo dnf swap wireplumber pipewire-media-session or installing
pipewire-pulse and running it.
Currently it looks like this:
pactl list short sinks returns this (I need 45, but the numbers keep changing):
35 alsa_output.pci-0000_0b_00.1.hdmi-stereo PipeWire s16le 2ch 48000Hz SUSPENDED 45 alsa_output.usb-Focusrite_Scarlett_6i6_USB_00052950-00.analog-surround-21 PipeWire s32le 3ch 48000Hz SUSPENDED 47 alsa_output.pci-0000_0d_00.3.iec958-stereo PipeWire s16le 2ch 48000Hz SUSPENDED
Number 35 works when selecting it with
pactl set-default-sink 35, but 45 does not. And furthermore, my audio interface, a Focusrite Scarlett 6i6, doesn’t even register mic input (it normally does, I can see the input light lighting up when I talk on the interface, even when connected to no computer at all).
It seems to be something wrong with it, but in Windows everything is still okay, and a with Fedora 34 and even a yesterday it worked fine with Fedora 35 for some time.
I have no idea what low level media server I have installed now, what I changed and what I didn’t change, so I’m glad to provide further details.
I would love to go back to the audio setup with Fedora 34, but I’m unable to make a clean uninstall of all current audio drivers or media servers etc and I don’t even know how Fedora 34 worked with audio. Even after reading the arch linux wiki entry for pulseaudio, alsamixer, pact and pipewire I still have no idea on how they are related and what they do.
