no sound in mac or bootcamp

I've got the red light syndrome and while I once was able to fix it by jamming things in the headphone jack, that won't work anymore. I thought if I installed windows on this computer it would work or I would be able to override it somehow.

Here is the weird thing. When I plug a headphone jack while running windows, the speakers play sound for a second, then it goes to the headphones. There has got to be a way to override this crap.

also, have no applecare and don't wish to solve this problem with money thanks

AND windows xp sp3

 

I think I've gone down the control panel route before BUT---- when sound playback, I only have one option (which should be the right one): Realtek HD audio output.

I've read a bit about this problem with bootcamp and I think it may have to do with the driver. Some people with the red light problem had no trouble as soon as they installed windows. I think my problem might be hardware. BUT MY SPEAKERS KEEP TAUNTING ME!

Thanks for the quick reply
