Chromebook CB315-2HT, Linux, sound driver I installed it and still no sound

fargodwe

I was gifted a Chromebook CB315-2HT last Christmas.  It uses Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Device 15b3.  The sound works fine in ChromeOS.  However, I found the Chromebook pretty useless for what I do, so I loaded a special firmware from mrchromebox so I have linux Mint installed in its place and boot straight to linux.  The sound, however, does not work.  Since the last I knew ChromeOS was supposedly built around the linux kernel I assume it has a driver for the sound that is compatible with the linux kernel.  Since the latest and greatest kernel 5.8 came out and it was to include a lot of driver updates I installed it and still no sound.  So - does anyone have a name, source, etc., for the sound driver?  I believe Google calls this CB "Aleena".

did you ever get it figured out?

Your kernel isn't the Chromebook kernel that has sound drivers compiled in, you need to deal with the Mint developers to get the right drivers.

Go to the Mint start menu. Open software manager. Search 'pavu'. Install PulseAudioVolumeControl if not already installed. Reboot.

I have the 516 GE, and I've got the same problem.
