Cheers for the reply.
I called apple and they went through my settings and things but they could not resolve it.
When I turn my volume down almost half way it's almost unable to hear what I'm watching.
Maybe the speakers in the 27" are not as good quality as in the 21.5"
Any more advise would be much appreciated.
Then, call back and request that they fix it. Do note that if you have AppleCare's protection plan and you're within 50 miles (80 KM) of an Apple repair station, you might be eligible for onsite repair since yours is a desktop machine (depends on where you're located). BTW, the AppleCare Protection Plan's the best warranty policy available for desktop machines. Get it if you don't have it before contacting Apple.
