Various audio problems with macbook pro
My laptop, which I bought around 3 weeks ago, is a 2.5ghz (upgraded processor) penryn 15" macbook pro. If it's worth anything, it's the model with a 512mb graphics card. I also upgraded the hard drive to the 7200 rpm version.
Anyways, I have been having problems with the right speaker as well as the sound in general. It was working perfectly until one day when I was watching a youtube video and the right speaker suddenly cut out. The only sound was a very high pitch whine that seems to constantly come from it until the speakers cut out to save power or whatever they do.
Now I know that hearing worsens with age, and I think that it's possible some older owners cannot hear this if they have the same problem. I am 18 and can hear it, my parents, on the other hand, cannot. It sounds almost exactly like it does when your ears are ringing, except higher-pitched.
As if listening to one speaker (the left one) and a high-pitched whine that hurts your ears after awhile isn't enough, I am also having problems with headphones. First, I am 100% positive that the headphones are completely functional as I also use them on my ipod and a PC (I also tried a second set to be sure). When they're plugged in, there is a constant static sound (until the sound cuts out to save power, that click is also really annoying), and when the system transmits a sound there are random beeps. It literally sounds like an R2D2 crawled into each of my ears.
Another thing I'd like to point out: when I restart my computer, both speakers broadcast the bootup sound perfectly. In fact, the right speaker continues to work for several seconds after logging in before it goes back to it's broken and whiny state. This makes me think it's a firmware problem.
Any help would be appreciated.

P.S. I have installed everything available from system update.
