Hi Jaroslav,
Had Your Redhat kernel implement the Intel SOF driver?
PCH Dmic need to enable by SOF driver.
If it had SOF driver, it doesn't need to apply this patch.
SOF could via UCM to control bass speaker volume.
Hi,
It's not correct. Those platforms have 4 speakers and we need to route the
stereo stream to all of them. The SOF driver uses the same HDA codec driver as
the HDA legacy driver (snd-hda-intel), so the situation is similar. UCM just
controls, if the second pair speakers is activated or not.
So, we need this for both legacy and SOF, otherwise the "bass" speakers will
be routed from another HDA DAC.
