No sound on Chromebook 11e converted from ChromeOS

es flag

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.

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 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!

@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.

If nothing else works there are very cheap generic USB audio adapters that always work. As cheap as $1 will do.

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. )

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
