Converted Chrome OS to Xubuntu 21.10 (tried 20.04) as well. All good but nod sound.

Mixer only shows dummy output. Tried some tricks from here but no luck: Fix No Sound (Dummy Output) Issue In Ubuntu With SND HDA Intel

dmesg showing error:

  • You may want to use this https://www.linuxium.com.au/isos instead of the standard Ubuntu installer. – ChanganAuto Dec 06 '21 at 01:03

    The Lenovo ThinkPad 11e Chromebook cost $341.05 when it was released in 2015. Today it is worth twenty bucks? Last year I tried out a modern Chromebook and it had no problem running both ChromeOS and Ubuntu at the same time. Sometimes it's a question of how much your time is worth investing in archaic technology. Oh I took the liberty of cleaning up the formatting in your question. I hope you don't mind. – WinEunuuchs2Unix Dec 06 '21 at 01:16
  • @WinEunuuchs2Unix Just wanted to mess around this old device and give my little girl, but no sound making it kinda useless. Thanks for making my question readable! – Belinda Fan Dec 06 '21 at 02:20
  • @BelindaFan The device is made for classrooms and designed for children. I hope someone with a similar device answers within 20 days to put a smile on a little girl's face at Xmas. – WinEunuuchs2Unix Dec 06 '21 at 02:24
  • If nothing else works there are very cheap generic USB audio adapters that always work. As cheap as $1 will do. – ChanganAuto Dec 06 '21 at 02:41

Try manually copying sof-bin firmware to /lib/firmware/intel/sof-tplg/ folder. See instructions in the answer of no sound due to error direct firmware load failed for intel/sof-tplg/sof-byt-max98090.tplg

(I am not a developer, just a regular user who encountered a similar problem. )
