i dont' believe there are any special processes running, but this iMac has always had issues since i got it. i've had it "fixed" 3 times for problems concerning the screen and video card, it's broken again so i'm scheduled to have it entirely replaced. perhaps there are some other underlying issues that aren't as obvious that is causing this sound lag problem?
NSSound *theSound = [[NSSound alloc] initWithContentsOfFile:@"mySound.m4a" byReference:NO]; would loading the sound into memory as above really make the first sound play on time? the size of my sound files average 40kb, so it doesn't seem reasonable to me.
