Speakers on Zenbook Oled S 13

[Yvanoff]

Hello all,

as you may know my main computer is a Zenbook Oled S 13 UM5302T 5Ryzen 7 6800U, 16GB LPDRR5-6400) - I had to ask for help here: https://forums.gentoo.org/viewtopic-t-1157644-highlight-zenbook.html because I had some issues bringing up the touchpad and touchscreen (everything is fine now though - thank you again pietinger !)

Now my new struggle is with the sound. I have no speaker output though the jack works fine (so for this reason it is not a critical issue but still annoying). At the beginning I accepted it because it seems nobody managed to get the audio to work on Linux on this laptop - something about the BIOS not exposing values necessary to configure the speakers.
However a BIOS update appears to have fixed it. And indeed nowadays if I boot a Ubuntu LiveCD on my laptop the speakers work. But I can't get them to work on Gentoo. I have enabled every audio option related to AMD SoCs and to the cirrus codecs (because this SoC is supposed to use the CS35L41 codec). To no avail.

Anyone with this laptop having a kernel config to share ? I'll link mine (as well as a dmesg, even if I couldn't really see anything relevant in it):

Yvanoff,

I think you are missing only this one:

I am probably bordering necromancy here, it's already been more than a year
But I did get the speakers to work not so long ago (and yes that means I went without speakers for 2 years after buying the laptop.... was not that much of a problem but still a minor annoyance)

As you suspected pietinger a module was loaded by Ubuntu to make the sound work and I had not enabled the kernel option in gentoo.... it was something i2c related, see here: https://wiki.gentoo.org/wiki/HP_Elitebook_845_G10#Speaker_no_sound

Thanks a lot for the help pietinger and whoever authored that article on the HP laptop !

You guessed right, yes, it was that serial option I was missing.... It did show up in the lsmod of the ubuntu install, I checked afterwards, but darn bugger was not obvious to spot
