(Get the code!)
Judging from 'dmesg', it seems that there's something amiss with the moduels included in the latest kernel update; for the audio, during boot-up, there's this:
[ 5.857193] soundcore: version magic '5.4.0-52-generic SMP mod_unload ' should be '5.4.0-53-generic SMP mod_unload '
and for the webcam:
[ 5.897814] videodev: Linux video capture interface: v2.00
[ 5.920217] uvcvideo: Found UVC 1.00 device Logitech Webcam C930e (046d:0843)

I wonder what else should I grep from 'dmesg' to help hunt the bug down. There's some kind of a screw-up with the libraries as for the kernel/firmware updates, that's all I can tell with my level of understanding. Hope someone can help me out on this one.
