Crappy sound on MBP late 2008

[jeroen870]

Hi,

I have this problem a wile now. When I play music (or watch a movie) I can hear there is something wrong with my sound output.
It's hard to describe, but is is like someone is playing with an equalizer. The high pitch sounds (voices) are constantly changing in volume. maybe the basses to, but its hard to hear that.

BUT, the strange thing is, when I play something in windows (parallels) it is much better... The bass is here more dimmed for some reason.

Does anyone know what is wrong?

If you can, post a video of it so we know exactly what it sounds like, or bring it to the nearest Apple Store, or call Apple.

Try going to Audio Midi Setup in utilities, and changing the audio out/headphone jack settings to 44.1kHz, 24bit. IIRC they're set to 16bit as standard, which is lots noisier...don't know if it'll fix the issue, but it should be changed anyway!
