On Ubuntu 20.04, by default, sof-audio-pci is used. I only have "Dummy
output" in pavucontrol. To fix this, I modified /etc/modprobe.d/alsa-
base.conf and added "options snd-intel-dspcfg dsp_driver=1" so that now
"snd-hda-intel" is loaded instead of sof-audio-pci. While the speakers
are working fine, I do not have the internal microphone working (suspect
a digital array).
