USB Microphone (Shure MV88+) disconnects with pulseaudio - sometimes on use, sometimes immediately - but works in ALSA
Summary
I have a USB microphone (Shure MV88+) that features audio input and output (to the earphone jack for monitoring). When I use it with arecord and aplay directly (using hw:2,0 as PCM and supported bitrate/channels/format) , it seems to work. But with pulseaudio it either disconnects immediately (and thus "cycling" through detect / fail to work / USB disconnect) or when I try to record audio (I used OBS with the Pulseaudio input).
environment
Thinkpad with Debian, alsa upgraded to 1.2.4, pipewire upgraded to 1.3.6, but disabled, pulseaudio. With the help of i-garrison on IRC (thank you!) I have collected various diagnostic outputs at http://lernapparat.de/static/pulse/ .
Steps to reproduce
Start pulseaudio and plug in microphone or the other way round (after disabling pulseaudio and pipewire).
