Comment 83 for bug 1871306

Status for sound on Dell Chromebook 3120. On Ubuntu 22.04.2 (kernel 5.15.0-69-generic):

1. alsa-ucm-conf now seems to include the required UCM2 files. Hurrah!
2. you also need the firmware-sof-signed package, which you have to enable the "restricted" apt repository to get. Some people enable "restricted" already, when they install Ubuntu.
3. after a few minutes continuous playback the sound breaks (continuous beep). This is fixed by adding the module/boot option snd_sof.sof_debug=1, as described here: https://github.com/thesofproject/sof/issues/5437

Secondly, this system is affected by the same "after setting snd_intel_dspcfg.dsp_driver=2 the Sound is Pitched down and too slow".

NOTICE: Upstream has suggested that future kernels will effectively default to "snd_intel_dspcfg.dsp_driver=2" on this hardware. I.e. the default would change from SOF to SST. If you have this "pitched down" problem, my only solution is to change back using the boot/module option "snd_intel_dspcfg.dsp_driver=3"
