Comment # 71 on bug 1201418 from Takashi Iwai

I guess the DSP stuff of CS35L41 still doesn't work properly.  Cirrus guy
mentioned that the boost patch was missing, and there might be also some AMD
SPI stuff missing for Cirrus, too.

For the speakers, we should go from the scratch again: try to remove the cset
from UCM config as much as possible, then restore the controls to the state in
alsa-info.sh output Tamara provided.  That is, the UCM profile will only choose
the device but won't touch the controls.  After that point, you can adjust the
control one by one and see whether it improves things or not.
