I see, this is different from how I've been dealing with it. Since I
always use uint8 format, but instead vary the rate to 352.8/705.6/etc...
Just because it's much more straightforward form the application's
perspective -> output rate is always bit rate divided by eight (=packet
rate). And switch between uint8 / uint32 sample format equals to switch
between DSD <-> PCM.
