I am completely new to Linux. I have Dell Inspiron and I have Linux Ubuntu 20.4. And I’m just starting to set some things in order. The other day I got the right codecs to be able to play videos.

But now I don't have any sound...
And I'm struggling to find the solution. So with a lot of research these are the facts -

  • In Sound Settings it displays Dummy Output.

  • I ran - pacmd list -cards - which gave me

    0 card(s) available ```

  • So, it's not detecting a Sound Card

  • I also ran - alsamixer and it returned

    No such file or directory

  • When I ran - sudo aplay -l and it returned

    device_list:276: no soundcards found...

When I play a video with sound then go to settings under Output Device i can see that it is picking up the sound but its not coming through the speakers. Can anybody tell me the right steps to take please?

I ran into a similar problem, All I needed to do was add

options snd-hda-intel dmic_detect=0

to the end of the file /etc/modprobe.d/alsa-base.conf

I still havent gotten my on-board speakers to work but now the soundcard shows up USB headphones and bluetooth headphones/speakers work fine.

If it doesnt you can also try adding

options snd-hda-intel model-generic to the same file

It may help!

  • I ended up doing both lines of codes and on both accounts it said - permission denied. But I decided to have another look at the sound in my settings and instead of saying Dummy Output it said - Speaker -sof-hda-dsp. so I ested it and it worked on my on-board speakers!!! Thank you so so so much!! I'm sorry that you still don't have sound on your on-board speakers. – Snoozirs Aug 09 '21 at 00:33
