After regular use, it was pretty clear there were audio issues with R4.1.1 and the P1 Gen 3. Audio would work periodically, and then degrade to the point there was no output. I was never able to pinpoint the actions that led to the degradation. I came across this post:
In short, creating an /etc/modprobe.d/alsa.conf file with the following contents coincides with functioning audio:
options snd-intel-dspcfg dsp_driver=1
This is a completely unscientific assessment, as I currently don’t have the patience to test it thoroughly.
