Thanks for your feedback.

In fact I also don't want to add sink_dont_move at very beginning,adding 
this "sink_dont_move" arguments because there is no reason to add 
"source_dont_move" only, it sounds weird and I can't answer question 
that "Why the sink have no XX_dont_move here,I just want to do this for 
my reasons?".So I add this one .
IMHO,we can ignore this argument in mostly situations and move the sink 
to default sink or other sinks when current sink are not available.

Falling back to the default sink may make some noises sound but not 
always,It's very occasional and may related to compatibility issue.
