An intial search showed two posts recommending a kernel rebuild when using the older Ubuntu 20.04 and another post elsewhere that I can't find anymore suggesting this was fixed with the new Ubuntu 22.04: https://devendor.github.io/c302ca/ Getting sound to work on Asus C302C (Chromebook) Any recommendations on an audio fix for an ASUS C302C Chromebook running a clean install of Ubuntu 22.04 via MrChromeBox UEFI?

I have working sound in ubuntu 23.04 with avs driver using https://github.com/eupnea-linux/audio-scripts and with kernel upgraded to 6.3.5. Default 23.04 kernel (6.2.0) didn't work for me.
Note: The repository got shifted to https://github.com/WeirdTreeThing/chromebook-linux-audio

Can you add more details of how you tweaked, so that future users can use it as well? – Archisman Panigrahi Jul 27 '23 at 07:10

Actually just selecting the correct device in microphone settings works for me. Also the audio scripts seem to have moved to https://github.com/WeirdTreeThing/chromebook-linux-audio – user1704879 Aug 02 '23 at 18:46
