What's the output of the file or link created by sudo alsa-info with root priveledges?

What's the output of the file or link created by sudo alsa-info with root priveledges?

Thanks for the quick response. Should I run that from the cros shell or from within the breath distro?

Also - I forgot to mention that in order to boot from Fedora I had to compile a 5.15 kernel with the config taken from the official Fedora kernel, as the default config provided by Breath was only giving me a black screen (I guess something to do with the amdgpu driver?). I'll try to do some tests to see what are the config options that are making a difference.

[MilkyDeveloper]

From within Breath :D

[eugeniodepalo]

Closing this in favour of #282 as I realize there is no point trying to fix the audio with a kernel not provided by Breath.
