My chromebook was working perfectly well with Lubuntu 20.04 (running natively). The sound was always quite low but it was ok. I installed the update 22.04 and now, the sound is either terrible or there is an intermittent loud beep for a few seconds. After the beep, the sound can return to normal or disapear. I tried installing Lubuntu 23.04, same problem, I also tried the solution explained here : Long beep sound in Acer c731 Chromebook while playing video: sof-audio-acpi-intel-byt 808622A8:00: error

With this solution, no loud beep anymore but a slower, low pitch voices version. I didn't try other things because I am not an expert and I couldn't really understand. I could reinstall Lubuntu 20.04, but at the price of not receiving any updates anymore. Can someone help me ?

Thank you

So, I found the solution.

I reinstalled Lubuntu 20.04, had no sound this time. Installed Mainline to test other kernels, tried 5.15, 5.19, 6.0, 6.2, 6.4, no sound working correctly with any of them. Tried to install Gallium OS before realising the project is abandonned. I reinstalled Lubuntu 22.04, with 5.19 kernel, still beep sound from time to time. Found this discussion on Linux Mint forum https://forums.linuxmint.com/viewtopic.php?t=386118

I followed what was instructed, to add options snd_sof sof_debug=1 to /etc/modprobe.d/alsa-base.conf, it worked, sound is good now.
