Thanks, Mark. 

Could you consider applying at least patches 1/4 and 3/4 for 6.8 as
well?

The former is needed for proper hardware volume control with the fixed
UCM files, and the latter avoids ending up with the digital gain setting
set too low or too high while by-passing the volume limit set by the
machine driver.
