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)'' ?
