Comment 84 for bug 1018020

Still reproducible for me with a Logitech C270 and kernel-default-5.13.0-1.2.x86_64 on openSUSE Tumbleweed.

A thread on the Microsoft support forum at https://answers.microsoft.com/en-us/insider/forum/insider_apps-insider_video/logitech-c270-audio-problem/f3cca299-5b3d-42ff-8471-b77520f1a9f4?auth=1 shows that Windows users are also affected, so this is probably a bug in the webcam hardware/firmware itself. Still, it would be nice if there were some kernel-level workaround.
