Sound card not detected - Ubuntu 20.04 - sof-audio-pci

rated 0 times [ 18] [ 0] / answers: 1 / hits: 26910 / 1 Year ago, fri, february 17, 2023, 2:44:00

After installing Ubuntu 20.04, I noticed that sound is not working on my system.

aplay -l was giving me Sound card not detected error.

Running inxi -A | grep driver gave me ... driver: sof-audio-pci

I tried some solutions on AskUbuntu, but they did not work and all of them used driver snd_hda_intel. Other pages said that firmwares for this driver are not shipped with distribution.

Is it possible to make sound work for Ubuntu 20.04?

As I said the sound driver I was running was sof-audio-pci, which had no normal firmware at the moment.

I searched nearly 3 hours trying to solve this headache and finally found the solution, just disable this "sof" driver and fall back to intel:

Do:

sudo gedit /etc/default/grub

Change

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash snd_hda_intel.dmic_detect=0"

Then do:

sudo update-grub

and Reboot.

You can check if soundcards are detected with:

aplay -l
