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.
