Ubuntu Mate - Acer CB3-111 (baytrail) no audio

I tried the 16.04 BETA on my Acer Chromebook flashed with SeaBIOS. Thanks to the kernal version, the mouse works fine. However, there are no options for sound. The volume key is grayed out. Would anyone know how to fix this?

I use GalliumOS, which is created to work on Chromebooks OOTB, but enjoy Mate and would like to give it a run for a few weeks, but I need my sound!


Hi @daffie,

try this, it should work on 16.04 too?:
