Public bug reported:
This seems to be a persistent problem that has been around a few kernel
versions earlier (see i.e.: https://bugs.launchpad.net/ubuntu/+source
/linux-signed/+bug/1881757 ).
After yesterday's apt update to 5.4.0-53-generic (amd64), my USB webcam
(Logitech c930) as well as my internal audio (Intel HDA) stopped working
altogether. All I get is a dummy audio output from the list of devices,
and the webcam is not working either.
I can still see my pre-existing audio devices with 'lspci | grep Audio':
##
00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High
Definition Audio (rev 05)
01:00.1 Audio device: NVIDIA Corporation GP104 High Definition Audio Controller
(rev a1)
##
'inxi -SA' reports this:
##
Audio:
Device-1: Intel 5 Series/3400 Series High Definition Audio driver: N/A
Device-2: NVIDIA GP104 High Definition Audio driver: N/A
##
(The #2 NVIDIA one being the video card's audio option, which I don't use, but
it's not listed as being available either.)
___
I've been trying to run ALSA's configuration and it seems that the ALSA
modules are not loading.
Also been trying out various fix proposals from people who've had the
same issue, but no luck on that frontier. Anyway, now I'm stuck with no
webcam, no audio. Any suggestions?
Thanks.
