Re: [BUG] ASoC: amd: yc: HP Notebook 255R G10 (board 8D22) missing from quirk table

Hi Mario,

thanks for the quick response. I'm not set up to build a custom kernel
locally yet.

Would it be possible for you to point me at a test kernel build (e.g. a
DKMS module, or a kernel build from your tree) that I could install and
test?

Alternatively, I'm willing to follow build instructions if you have a
recommended workflow.

Regards,
Alen
