How to minimize delay when playing an audio clip

Another trick that I’ve used in the past (when using players; I’ve haven’t used imported audio clips much) is to play a very short, silent audio file at some point in a preOpenCard or openCard handler. This kind of gets the audio ball rolling so to speak, then when I need to play my actual audio, there is no delay. Whatever needs to load in the background in order for audio playback has already loaded. A bit of a hack I suppose, but it works. :-)
