Hi,
I have a Logitech camera C920 which I have been using for around 2 years. Lately it has been happening when in a videocall using Zoom or Teams, and the mic just goes silent. I use gnome, and I go to settings/sound and the mic is dead (the input device bar doesnt show anything). Eventually it will come back, but then it goes again at random. Unplugging and plugging again the USB seems to work, but not always.
I haven't used the camera that much, perhaps I have 1-2 calls a week.
Checking the journal, more or less when the mic went silent, it shows the following in red:
Aug 29 15:48:34 housepc pipewire[1222]: spa.alsa: front:2: impossible timeout 703 1431655253 7444794896729 52183999584229 44739204687500 171 21794337
This message seems to be repeated thousands of times, several times per second. Until the call stopped. During that time my mic was not working, but during the first 10 min of the call it was working fine.
