Bug Description
Occurs only with my audio interface Steinberg UR22C, which is connected via USB-C.
This is a regression.
Latest kernel known to work properly was: linux-image-
(If I boot my current system with this one, everything's working fine.)
As far as I can tell this broke with vthe v5.4.0-51 update.
## Problem 1:
On reboot: after a few seconds playback stops (and freezes the application that was currently playing audio).
### For v5.4.0-56
This happens only once after each boot. Works fine after closing the hanging player.
### With v5.4.0-51
This used to occur again and again, plus the playback freeze was permanent.
Workaround: pulseaudio --kill +then: pulseaudio --start until the next freeze would happen)
### Characteristics
Audio would suddenly go completely silent.
## Problem 2:
Applies to v5.4.0-56
After starting some playback the first few seconds will also "contain" some unpleasant weird crackles.
