Audio not working, only audio device is "Dummy Output"

I am on Pop!_os, latest version I could get.

My board name is KASUMI. It mentions I need to get firmware built-in, but not sure how to do this. I also ran the audio fix script, still nothing.

On KASUMI you need to compile a custom kernel with the AMDGPU driver and the respective firmware fully integrated into the monolothic kernel instead of made available as a kernel module.

There is a script which is supposed to compile the kernel at GitHub - chrultrabook/stoney-kernel: Script to build the weird kernel needed on stoneyridge chromebooks, but I have never tested it because I don’t have a Stoneyridge device.

Thanks, also, can you do something either than alpine with the script?

I think that question is answered by the contents of the repository.

Kernels aren’t necessarily supposed to be distro-specific, but ymmv. At any rate, the script is clearly designed to support multiple distros, it just currently doesn’t, so anyone could add support for another distro to it if they know how.

Compiling with AMDGPU=Y is no longer needed, you can use this patch instead. stoney-kernel/patches/audio.patch at main · chrultrabook/stoney-kernel · GitHub

how would I use it / install it?

You would need to compile your own kernel or wait for someone to compile and share one.

when I try to compile it, I get

"file: invalid option – ‘S’

"

Ubuntu 22.10 had support it.
