 	src/sys/dev: audio.c
 
 Log Message:
 Use correct combination of mix ring block size and vc playring used low
 for signalling the writer or fetching data from the vc play ring filters.
 
 When dealing with the ring buffer sc_mpr.s it is necessary to use the hwvc
 or mixring block sizes as they represent the final size of the data to be
 played back from the stream vc.
 
 When dealing with sc_pustream when there is play back filters or not one
 should use the vc->sc_mpr.blocksize, as this represents the amount of data
 before going through play back filters.
 
 This should address PR kern/52685.
