We've seen the issue on 3 different macs, all about 1-2 years old. Each one we have the core audio set to stay awake, and we set the screen saver off and the hard disc to stay awake, but the problem still resulted. The silence cues seem to be keeping things happy for the most part, but I'm hoping a long-term solution presents itself on this one.

The problem does not seem to be specific to the computer or interface, as we have had it happen on all 3 machines, each of which is connected to a different type of audio interface (Layla 3G, MOTU828, MOTU Ultralite). There's also been no predictable pattern, each machine gets a fresh boot prior to the show starting, and a speaker check cue.
