How to minimize delay when playing an audio clip

In the past, it used to be that imported audioClips would generally start
playing with less lag than players.  I haven't done tests with any of the
recent versions of LC to see if this holds true (sounds like it doesn't?).

In any event, I've never done this, but you might try using an imported
video clip with no video track (if that's possible) so it contains your
audio only, and use the prepare command, which supposedly allows the
imported media to start playing immediately. If you can't make a
video-less movie, another option could be to make the video 1 x 1 pixel in
size.

Even if a videoClip somehow employs a player for playback, the prepare
command might reduce the start lag.
