No really, what is it that makes mplayer
(1) play a given file using libao [AO SUN] which tries
to open /dev/audio (and fails because /dev/audio is already
opened by the running aucat) in one case
and
(2) play another file using sndio, which works
in the other case?
Also, what't the point of (1) falling back to AO NULL
and going through the file while playing nothing?
Is this AO behaviour (as opposed to mplayer's logic)?
