Okay, newbie here I'm just wondering whether it's safe to call AudioServicesDisposeSystemSoundID() on a sound I'm not sure has finished playing ... or whether I should set up some sort reference counting system by calling AudioServicesAddSystemSoundCompletion() whenever I create a new sound, and only dispose of all the sounds when the reference counting system says they've all finished playing for sure? Oh yeah, this is on an iPod touch
