I noticed that since I upgraded to fedora 35, now video playback stops working almost system-wide from time to time. I say almost system wide because VLC still plays video, but gnome video doesn’t, and neither youtube nor imgur in Firefox (not even mentioning other browser, with which I can recreate this issue at will by just opening youtube on chrome for instance) can play videos either when it happens. This kills audio system-wide though, with even VLC not being able to reproduce sound,same for rythmbox. After logging out and in again, all my audio input/output are gone, and replaced by a single dummy output. I have to reboot every time it happens to get it work again.
I have no idea where to start troubleshooting this. Thanks in advance for any help!
If it can help this is happening on a t14 AMD thinkpad.
edit : bluetooth seems to trigger this problem too, I had something connect automatically to the bluetooth and had the same issue again even though I had just restarted …
