Mac Mini Audio Trouble Options

[JBeat]

I'm a first-time Mac user, and first-time poster on this site. After spending way too many years fighting Windows PC's, I finally made the switch and picked up a $599 Mac Mini w/512MB of RAM. As I've heard many say before, I'll never go back, I'm already a Mac fanatic after two weeks! I love everything about the Mac, especially Garageband, however, I'm getting a buzz when my speakers are plugged into the headphone jack. I've tried several sets of speakers, with the same result. If I keep the volume of the speakers very low, I can't hear the buzz, but I have to max out the Macs volume, and sometimes it's not quite loud enough. It's frustrating because I have a Creative 2.1 system with subwoofer, but I can't cut it loose on my tunes. Does anyone have any suggestions?

Thanks.

One thing jbeat....the methodology in music systems is always to keep your source as loud as possible..this means that you have good dynamic range at the outset and it keeps noise as low as possible...with computer speakers this means always always having the mac volume all the way up, itunes up, garegeband up , all of them up and using the creatives volume control to manage the level through the speakers.
See what your results are after that ok..

Um, is it a buzz or a hum?
You know, buzz like when a crt monitor's too near a guitar or a cable ( turn the screen off to check ), hum like er, 50 /60 Hz mains frequency sort of a hmmmmmm not a bzzzzzzz, not a click click brrrr or a squirt squirt cheepp cheep chirrrrrrt or any of those type either
