No sound in Apollo Lake Chromebook

Kernel 4.19 but same problem with 5,10 and 5.11
Alsamlxer shows Intel Broxton HDMI but I saw somewhere that Broxton detection is a mistake.
Please help me configure
What additional info should I provide?

I might not be able to help you, but the info would be necessary for anyone to help.
