I am new on Linux, running Ubuntu 20.04.4 LTS without other OS. I found out that my output audio is dummy and no analog sound card had found. I'm not sure what is the cause. These are command output :

$ alsamixer

$ pavucontrol

I have tried :

...and other suggestions that I had found and I even couldn't remember the links, but still not works.

Also I couldn't access Advanced Tab on BIOS to see if my sound card had been disable accidentally since manufacture hide/ disable it.

Please kindly help me.

Your answer would be highly appreciated.

Same issue with Xubuntu 23.04 on my Minis Forum GK41. I've try a lot of solution for a day and finally resolved wit this link: https://www.linuxuprising.com/2018/06/fix-no-sound-dummy-output-issue-in.html

Basically you need to edit two files like explained in the second part of the guide.

  1. Edit /etc/modprobe.d/alsa-base.conf as root and add options snd-hda-intel dmic_detect=0 at the end of this file.

  2. Edit /etc/modprobe.d/blacklist.conf as root and add blacklist snd_soc_skl at the end of the file.

  3. After making these changes, reboot your system.

To be precise now the Audio Output works with HDMI, still can't use my audio jack, but hey... that was what I need!
