Samsung Chromebook Pro - speakers not detected

Support Sound
1

Greetings,

I’ve freshly installed Manjaro (plasma) on my old Samsung Chromebook Pro (Caroline / Intel m3-6y30) and everything works great except the integrated speakers. Manjaro can’t detect them at all, but when I connect my bluetooth headset, the sound comes out alright. 3.5mm jack doesn’t work though. I’ve tried the solutions suggested on ArchWiki (even though they’re for different boards/chipsets) but haven’t had any luck. I’ve tried looking through various forums as well to no avail, so I’d greatly appreciate any help you could offer.

Attaching my inxi -Fazy output:

thank you in advance

Did you try swithing kernels?
You can use system settings > Kernels to install another kernel
and then select that kernel when grub menu popsup to boot into that kernel

3

Tried installing the 6.something kernel. The device wouldn’t boot, couldn’t even access grub so now I’m waiting for another fresh install to finish. Hopefully the other ones won’t break my system too :confused:

4

update: I’ve managed to install the 6.0.2-2 kernel without any issues this time but unfortunately it hasn’t solved my speaker issue, and neither has any of the other ones.

5

So after installing kernel your system was unable to boot?
Did the installation finish sucessfully?

And after successfully installing it, Did you boot into that kernel?

I would recommend that you try installing another LTS kernel and booting it.
You can find LTS kernels list in the linnk below

hi, yea the first time I installed the 6.0.2 kernel it broke my system. After that I reinstalled manjaro and enabled grub menu on every boot so that I’d at least be able to revert to one of the older kernels just in case it broke again, and afterwards installed 6.0.2 again. It’s working alright now, so I have no idea why it broke the first time.

Anyway I’ve tried several of the newer kernels but none of them seems to be able to detect my sound card (cat /proc/asound/cards returns – no soundcards --), which is weird since I can play sound just fine provided it’s through bluetooth speakers or headset. Only the built-in speakers and 3.5mm jack don’t work.

Try to follow this, same sound card not sure it’s the same chromebook, was the top result when searching “arch linux chromebook Intel Sunrise Point-LP HD”:
