 Module Name:	src
 Committed By:	nat
 Date:		Sun Oct  1 21:49:20 UTC 2017
 Modified Files:
 	src/sys/dev: audio.c
 Log Message:
 Ensure proper use of sc_opens (play back) and sc_recopens (recording).
 Fix logic for /dev/sound so audiosetinfo is only called once.
 These changes are to ensure that init_output/input is only called once for
 the respective function play back or recording.  For multiple recording or
 plack back streams init_input/output is only called once fot the first
 play/rec stream.
