My system is a Linux MX-23.4, sound system is Pipewire and I use a USB audio interface (a Focusrite Scarlett 18i20).
I have been having the following problem for a few weeks:
after turning on the pc and logging in, the system recognizes the sound interface and works correctly. But after a few minutes or more the audio no longer works and if I click on the audio management icon, it tells me “no input or output device found”.
The sound card is still connected, in fact I’m still able to manage it with its software.
So I thought that the problem could be in the audio system, in Pipewire.
This is what dmesg says:
$ sudo dmesg -W

If I close the session and log in again, it starts working, but only for few minutes. If I listen to music, it keeps working for much longer.
Any ideas what the problem might be? And obviously how to fix it?
