alsa-project/alsa-lib issue #284 was opened from Konfekt:

Hello,

`journalctl -p err` showed the message

``` pulseaudio[15806]: Most likely this is a bug in the ALSA driver 'snd_usb_audio'. Please report this issue to the ALSA developers. ```

Hopefully this bug tracker reaches the ALSA developers? Here's more output:

Curiously my bluetooth headset switches off in Zoom after around five minutes and can't be reenabled. In the hope that this error message gives a hint. Attached further alsa-infos.
