need help please! USB and audio problems, is there a good and bad USB port?
i really need some help with a problem on my macbook pro. (sorry if this thread is in the wrong area btw!)
i turned my macbook on a couple days ago to show someone a track ive been working on and when i played it the audio seemed to be crackling/hissing while sound was played so i closed logic and opened itunes, still hear the crackling so i shut it down, still no change when it was back on, i plugged the usb from my audio interface into the other usb port and luckily it was fine.
yesterday it happened again and is still doing it and i really cant find a way of fixing it as the speakers are fine, when i play an instrument through the audio interface its fine, the usb lead is fine as i tried another and no change, its literally only when any kind of sound is played from my laptop.
also ive noticed today one of the usb ports seem to not be recognising anything now! my audio interface..memory stick..usb mouse.. nothing! this i very frustrating as im doing a music degree and unable to continue my work because of this. does this mean that the usb ports are broken or something?! if so how do i get this fixed?/how expensive will this be!

im not sure if any of this would be related to the above problem but over the last few months ive noticed the battery seems to last 4hrs at max, if i watch a film from full charge it will say only 1hr of battery left which is wrong because it ends up lasting for about 20 minutes. also when its running on the battery it gets quite hot (a lot hotter than another macbook pro i compared it to) from the top left corner roughly down to the caps key and across to the F key, quite a large area, but when the power lead is plugged in its fine and cool.
ive had this macbook for over a year now, think i got it a couple months before the one that came out with the thunderbolt port (gutted on my timing!)
thanks in advance for any help, much appreciated.
