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) [ 5.922925] uvcvideo 2-1.4.4:1.0: Entity type for entity Processing 3 was not initialized!

[ 5.922942] uvcvideo 2-1.4.4:1.0: Entity type for entity Camera 1 was not initialized! --- 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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1903848 Title: Latest kernel update to "5.4.0-53-generic" = Internal audio, USB webcam no longer working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-signed/+bug/1903848/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
