Linux Kernel 5.19 Soundcard not working ASUS chromebook C433

#1 Post by BrickedPc »

Hello, this is a follow up to my previous two posts from 3-4 months ago:

> viewtopic.php?f=7&t=152512
> viewtopic.php?f=7&p=756859#p756859

Basically the issue is, that no audio device that is connected directly to the soundcard is detected, meaning neither the inbuilt speakers nor headphones work. The only way currently to use a device is to connect it per USB or Bluetooth. After not being able to solve this issue, a person from a previous post mentioned, that support might be missing, since intel changed the audio drivers for their Kabylake CPUs. Support was coming with the Linux Kernel 5.19 according to this article: https://www.phoronix.com/news/Linux-5.19-Sound

I updated to 5.19, but still can't use the soundcard and was wondering if there might be any new things I should try. So far I have retraced every step once from the previous forum posts, but to no avail. Here's some information about the system. Hopefully that will help:
Kernel version:

Code: Select all

 debian@debian:~$ uname -a
Linux debian 5.19.0-0.deb11.2-amd64 #1 SMP PREEMPT_DYNAMIC Debian 5.19.11-1~bpo11+1 (2022-10-03) x86_64 GNU/Linux 
Some extra output regarding audio devices:

Code: Select all

 debian@debian:~$ lspci -nnk | grep audio
