I and my friend Ivan Fonarev also tried to do that. We can't hear the sound!

Hello! I've set up an Ubuntu 20.04 install with the stock ChromeOS kernel (release-r96-14268.B-chromeos-5.4). The sound card is correctly detected (kblda7219max):
aplay -l:
**** List of PLAYBACK Hardware Devices ****
card 0: kblda7219max [kblda7219max], device 0: Audio (*) []
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: kblda7219max [kblda7219max], device 4: Hdmi1 (*) []
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: kblda7219max [kblda7219max], device 5: Hdmi2 (*) []

card 0: kblda7219max [kblda7219max], device 6: Hdmi3 (*) []

I've copied neccesary FW from ChromeOS into my rootfs. I tried this and it worked a month ago (can't recall the commit sadly). Here is my github page: https://github.com/MilkyDeveloper/cb-linux

I am using a completely stock ALSA setup without PulseAudio.

I've also attached my lspci -v, lsmod, and dmesg output:

It doesn't work with NAMI/VAYNE.
1) Cannot mount to /mnt error
2) Sound card is detected, but doesn't work. 
3) Snap apps don't work correctly. Something wrong with SELinux.

For any other tinkerers: I have fixed this by using kernel 5.10.70, which you can use here: https://github.com/MilkyDeveloper/cb-linux
