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.
