firstly; thank you for putting this all down. it is indeed a nice laptop, however, the sound issue drove me bonkers. i had it working in 18.04/19.04 but haven't been able to fix it in 20.04. thank you for the kernel building instructions.
now, i wanted to convey a warning based on my experience. i decided to purge chromeos for good, and installed the uefi firmware from https://mrchromebox.tech/#bootmodes (the rabbit/tianocore) and run ubuntu 20.04 that way. initially, it seemed ok, but the system kept getting disk corrupt errors (crc errors on the journal, ext4), on both the internal drive and the sd card slot. i tried many, many, (many) things, but nothing would resolve the appearance of write errors. eventually, i gave up and restored seabios (aka Legacy BIOS) and it has been stable since - and yes, the horrible dev screen, but set to a 1 second pause.
i'm curious if you are running seabios or tianocore. and if you had any disk errors with tianocore?
