 vs(4) still does not work.
 
 By the way,  current vchan_autoconfig() (in sys/dev/audio.c)
 seems try all frequency formats of all channel numbers of all
 precisions.  Is it right way?
 
 IMHO,  is it not enough that ''try SLINEAR/44.1/2ch first
 and if fails then try mulaw/8k/1ch (for backward compatibility)'' ?
