[QUOTE="msouth, post: 1396639, member: 249276"] [b]My guess: network operation blocking?[/b] Since iTunes communicates over the network, and network operations are pretty much notorious for making everything else stop and wait (not really the network operation itself, but the way the coder programmed it--it's a lot harder to say "hit this server, and, here, I've got a function that I want to be called when a response comes back, and until then I'll make sure everyone else can use the processor btw" than it is to say "hit this server, wait for the response, then do this next thing". If that's what's going on, it could be like this: * Normal daily operation: itunes does its thing, and hits the network occasionally, blocking all other operations until it gets a response. The audio playback has some buffer of stuff it can play until it needs to go get more data, decode it, and play, and that is enough to not have any problems, because the network stuff is coming back quickly * Bad day: network is slow either between you and the server or at the server end. Occasionally the audio runs out of buffer, asks the system to give it more data but the system is like "sorry bub I'm waiting for this server to talk to me hang on a sec" PURE SPECULATION.
