I just purchased a new 3.06 iMac, and I must say I am very happy with it! However, there is on very annoying thing- Every time it goes to access the audio and sends a signal to my Klipsch speaker set, there's a loud "crackle" as the audio initiates. Wow! Annoying as hell and not what I would expect from Apple! Even my ancient PC's didn't do this! Anyone know of a fix for this, or am I stuck listening to this crap for the next 3-4 years?
