No sound with my enigmatic Pentium Silver HD Audio

[SirLouen]

First, I have to say that I have probably bought the worst laptop in the history of Linux
After this
And this (solved at least, yay!)

Now comes my third nightmare: No Sound with a weird card

First of all the inxi output we all love in this forum:

Here we can see this driver: sof-audio-pci-intel-apl

If I do the aplay -l:

Code: Select all

# aplay -l
aplay: device_list:274: no soundcards found..

I can switch to the intel legacy hd-intel driver with modprobe.d option:

Code: Select all

options snd-intel-dspcfg dsp_driver=1

But still no sound despite this switch. With aplay -l I get a number of results like:

Code: Select all

I have downloaded and installed the 2.2 firmware from repo: https://github.com/thesofproject/sof-bin
(Anyway I had the 2.0 firmware so I think it was not an extreme change)

Neither pulseaudio or alsa recognize a soundcard:

Alsa:

00:0e.0 Multimedia audio controller [0401]: Intel Corporation Celeron/Pentium Silver Processor High Definition Audio [8086:3>
        DeviceName: Onboard - Sound

So far I haven't found any other workaround to proceed.

A quick web search for your soundcard in Linux turned up https://askubuntu.com/questions/1237007 ... 3xxx-n3xxx which suggests adding this boot parameter right before "quiet splash":

Code: Select all

i915.disable_power_well=0

which IIRC you can do to test it by pressing E at the grub menu screen then using your arrow keys to navigate to that quiet splash text and add the parameter, then finish booting. If sound works you can add the parameter permanently in MX Boot Options.

Just out of curiosity, How could you find such answer with the information I provided? It doesn't any of my hardware specs
I'm going to test it anyway and report back

I highlighted the sound card (audio) info from your Quick System Info, right-clicked on it, clicked on "Search duckduckgo for..." (my search engine of choice) then in duckduckgo I added the word linux to the search keywords and clicked search again.

Where did you get the 6.0 rc 7 kernel from? From Debian Experimental?

I compiled it from sources. Anyway it doesn't work either in the base kernel
