Please help: audio dropouts (tried everything I know)

[soundsliketree]

My gear:
Newest MBP17, 4GB RAM, 10.6.3, 8.1.3b1, and a bunch of AU instruments

My situation:
I've got a new show running. In the arrangement I have a couple tracks with the background material and then I arm various instrument tracks and play on top of the backing tracks.

My problem:
When I play an instrument for the 1st time in the show it causes the main backing tracks to drop out for a fraction of a second... sometimes. The CPU never goes above 30%; my RAM has room to spare. I've tried making my main tracks RAM clips. I've tried messing with the buffer size... Still the problem occurs.

Can anyone offer me any more things to try?
Thanks in advance!

I'm experiencing a similar problem with Live 8.13. Every time I change track focus, there is a brief audio dropout.

Instead of starting my own thread, I figured I would just add to this one. I just did my first show with Ableton Live last night and experienced several audio dropouts. Actually, it is more like an audio freeze because the audio doesn't go away and come back where it should be in time as if the volume was turned down for a brief second. It acts more like someone hit a pause button and the audio comes back right where it left off. My CPU load indicator is clocking at a whopping 3% (that's right THREE percent). I don't see the disk overload indicator flash (or whatever it does), but then again who has time to stare at that all night long. Does anyone know of a "history" log that would tell what happened?
