Sound card no longer recognized after upgrading from 20.04

Question

Dell Precision 5750, on 20.04 the sound was working just fine.

But then, when I upgraded to 20.10, the system stopped recognizing my sound card, and a further upgrade to 21.04 didn't change anything. Force reloading/reinstalling alsa didn't help.

Sound settings say "Dummy output" as an output device.

Alsamixer only sees HDA Nvidia as a sound card for HDMI. So does "aplay -l":

So I surmise that my card is an onboard Intel Realtek something, and that it should use the snd_hda_intel driver. I've also double-checked that it was switched on in BIOS.

Any ideas where to look next?

Try

$ sudo apt-get install linux-modules-extra-$(uname -r)

Also post the output of

$ modprobe --show-depends snd_hda_intel

in the question

Already tried installing linux-modules-extra, says it's already the newest version.

I also tried looking at dependencies as well, but can't really tell which are installed and which aren't by this output:

insmod /lib/modules/5.11.0-17-generic/kernel/sound/soundcore.ko 
install /sbin/modprobe --ignore-install snd $CMDLINE_OPTS && { /sbin/modprobe --quiet --use-blacklist snd-ioctl32 ; /sbin/modprobe --quiet --use-blacklist snd-seq ; } 
insmod /lib/modules/5.11.0-17-generic/kernel/sound/core/snd-timer.ko 
install /sbin/modprobe --ignore-install snd-pcm $CMDLINE_OPTS && { /sbin/modprobe --quiet --use-blacklist snd-pcm-oss ; : ; }

I suggest you:

Post all additional info by editing the question, not as an answer.

Post the output of all commands in https://askubuntu.com/questions/1258510/only-dummy-output-sound-in-ubuntu-20-04-after-reboot-broken-driver-modul

Use appropriate markdown formating.

All this increases your chances of solving the problem. The time invested will surely pay off. — sancho.s ReinstateMonicaCellio, May 18 '21 at 10:40
