// This code was reorganized so that if all audio tracks
// are muted, we still return paComplete when the end of
// a selection is reached.
// Vaughan, 2011-10-20: Further comments from Roger, by off-list email:
// ...something to do with what it means to mute all audio tracks. E.g. if you
// mute all and play, does the playback terminate immediately or play
// silence? If it terminates immediately, does that terminate any MIDI
// playback that might also be going on? ...Maybe muted audio tracks + MIDI,
// the playback would NEVER terminate. ...I think the #else part is probably preferable...
