It seems that your output device isn't detected by cras (ChromeOS Audio Server). Did you say that you enabled chromebook audio? What recovery image are you using?

[Yunjonue]

I tried with both of enabled and disabled chromebook_audio I use Volteer, Voxel, 115 (which was suggested in the official documentation) Also I use stable Brunch version (r115) and didn't update system in any way

[ZProLegend007]

Your device (I believe) originally runs Windows. Have you tried running linux on it before? I think there may be issues with drivers and/or soundcard detection. You need to figure out how to get your soundcard detected so that the system can output to it. Try to do some research on similar issues for your device running linux online.

[Yunjonue]

Yes, I did. My computer runs Windows, but I installed Linux. Thank you for advice

[ZProLegend007]

Coolio, does sound work in Linux? As ChromeOS is built on Linux if the sound works on Linux alone then you could try install the same drivers on ChromeOS.

Good luck! Hope you figure things out.

[Yunjonue]

Yes, it works on Linux. I'll try, thanks 🙂 Maybe also different recovery images can help? I can't figure out how to find a correct one for me, there's no difference, for example, between "rammus" and "volteer" at first sight, but they are for different CPU generations

[ZProLegend007]

Try the "voxel" image. That image is said to work best on intel 11th gen devices. https://cros.tech/device/voxel/

Edit: Never mind I misread the above, I see that you are already using it. Try find what config your Linux is using (if it's still installed) and figure out what modules, drivers or firmware may be missing. Let me know what you find 👍

My Samsung Galaxy Book2 with 12th Intel Core i5-1235U has no sound. Everything else works normally, including the microphone, only the sound doesn't work. I've already tried several images from Brya, now I'm testing with Primus, but it didn't work either.

After downloading the sof firmware, refer to this method. https://github.com/sebanc/brunch/issues/1859#issuecomment-1689698613

And it might be worth checking out the additional steps here: https://github.com/sebanc/brunch/issues/1692

@ly9999999, hi again! I found that for my sound card, the sof firmware comes OK with current brunch (118) and kernel 6.1, but I need to run an extra script for ALSA to fit.

[Yunjonue]

with new Brunch version and kernel 6.6 audio appeared and works fine. don't need any additional drivers or parameters
