I apologize if this is too much off-topic from the original issue…can hopefully split to another thread if it is…
I also recently did an upgrade 20.04 > 22.04 > 24.04, and ended up with a working sound system, but I somehow broke it when installing some additional packages to get at some additional features of my sound card. My issue is the dreaded “Dummy Output” listed for the Output Device in Settings, with no sound cards available.
In my case, whatever I did now prevents the drivers snd_cmipci and snd_hda_intel
from loading at startup. If I manually execute the modprobe commands shown below in the hwinfo output, the sound cards show up in Settings and wpctl, and function properly.
I’ve tried removing/purging/reinstalling alsa, pipewire, ubuntu-desktop, stopping/restarting various sound components with systemctl, and alsa force-reload, and other things as well.
I have probably whacked a configuration file (or files), but I can’t seem to figure out how to get the Ubuntu to recreate the proper startup sequence or regenerate the damaged files.
Any thoughts?
