Need help with audio

I have a Kasumi360 chromebook and I have recently install arch linux on to it but there is no audio I have tried using the script to enable the audio but it just says i need to install a different kernel but I have no clue how to do that

Perhaps the Arch Wiki may be useful to you here Chrome OS devices - ArchWiki

Different kernel…
Are you using the the regular kernel,sould be called linux 6.8.9.arch1-2 or something,you can check with uname -r.

Kasumi 360 is an AMD Stoney Rridge system needing a “-stoney” kernel.
