Hey guys I just got my iMac yesterday, and its been awesome, but I have one question. The classic "bong" sound at startup, i know that is the result of a successful POST, but mine didnt do one after the 1st startup. I had speakers plugged in to it when i started up the 2nd time, and no sound. I unplugged the speakers, and I got the sound. Is that normal or do I need to contact Apple? I jut want to make sure nothings wrong with my iMac. I checked the POST results in System Profiler and it said Passed, so any thoughts here?
