Just got my 2.4 SR macbook, had a blackbook previously. This thing makes the strangest noises, if i scroll with two fingers on the trackpad it makes noises like a hiss. Before and after sound effects play it hisses and sometimes i notice it is just making white noise. I know these are documented issues what i wonder is are they fixable through firmware ? or is this something that is hardwired into the computer and will be a problem forever ? Seems terrible.
