arecord records fine right after restarting pipewire, but once I play any sound, it stops working with the below error, until another pipewire restart.
$ arecord --device="plughw:2,0" ~/test.wav

Some context: I was enjoying voicecalls & youtube playback with the same mic+headphone+DAC until recently, with Pulseaudio. Then there was a problem where playing Youtube videos crashed the DAC entirely, and I switched to Pipewire following advice on discord linux. Now playback works perfectly, but I can't make any voicecalls with the above problem.

This kernel bugzilla looked a lot like my problem, so I downgraded to 5.19.8 but the problem persists.
Also I went back and forth between Pulse & Pipewire and now the mic just never works anywhere.

The issue is gone, I just had to properly disable pipewire after the downgrade.
