alsa-project/alsa-lib issue #152 was opened from sambo57u: I have a Logitech C922X (detected as C922) USB webcam. Running latest updates on Fedora 34. The microphone of this device only works about 1 out of 5 reboots. When not working if I install another microphone, activate that one, the unplug and plug C922 back and switch to it, it starts to work. Some kind of a timing issue that is very annoying. Don't have this problem with Logitech C270. The camera always works fine. Issue URL : https://github.com/alsa-project/alsa-lib/issues/152 Repository URL: https://github.com/alsa-project/alsa-lib
