[SOLVED] Internal Microphone not detected

[lolokatz]

Hello,
I had audio issues after the installation of LM20.1 on a brand new Dell Inspiron 15 3000.

The loudspeaker were not working at all, I could solve this by adding the option ="snd-intel-dspcfg.dsp_driver=1" into GRUB_CMDLINE_LINUX_DEFAULT of the etc/default/grub file.
The sound is working / the hardware is detected some seconds after logging in (but not directly) but this is not my real issue.

The other issue is the internal microphone which is not detected (the headset works). I tried several solutions found on this forum and other ones but none seemed to work for me.

I would be glad to find some help!
Thanks a lot in advance!

The loudspeaker were not working at all, I could solve this by adding the option ="snd-intel-dspcfg.dsp_driver=1" into GRUB_CMDLINE_LINUX_DEFAULT of the etc/default/grub file.

And doing that guarantees you'll not get your Internal Microphone working. That command forces the legacy snd-hda-intel audio driver, and your microphone requires the new sof audio driver.

We can try to get all your audio fixed, but you'll first need to undo that grub change, then reboot and run this command to get a look at your sound setup:

Code: Select all

curl https://gitlab.freedesktop.org/pulseaudio/pulseaudio/raw/master/src/utils/pa-info?inline=false | bash | nc termbin.com 9999

The last line of output will have a URL pointing to the info. Pasting that URL is all I need.

Hello MrEen,

thanks for you reply.
I undid the change in the grub file and executed the command. But now the loudspeaker are also not working anymore...It seems the sound card is not detected.

Thanks in advance!

Okay, I've seen an issue like this recently that I'm hoping you won't require the same fix for, as it's very convoluted.

First, try going to the Update Manager > View > Linux kernels and install the latest 5.8 kernel there. Reboot when done and test your sound.

[lolokatz]

It worked! After the reinstall of the Kernel 5.8 the audio card was detected.
Thanks a lot!

[MrEen]

Whew!

I'm glad that was all that was needed as the other fix is really tough to get right.

And just for completeness, the microphone works as well, correct?

[lolokatz]

Yes, exactly. Both the sound and the microphone are working

[MrEen]

Fantastic!

Glad I could help.
