The current focal-proposed kernel (5.4.0-18.22) has all the sof patches
from the list, and I don't see this issue anymore, so I guess this
firmware is okay to go in once that kernel is in the release pocket.
However I will note that audio still doesn't work optimally on my
lapttop. The speaker volume is very low, and the internal microphone
doesn't seem to be working at all. Are these known issues, or should I
file a bug?
