Ok, ive got a nforce2 mobo with onboard sound. Running windows XP. with nvidia nforce audio. I set it up as 5.1 speakers, and check the line in to rear speakers option. So far no issues, then when i play somthing in winamp, no sound from the rears. Ok, i can deal with that. However, when i play somthing in WMP, i get a 1-2 second delay on the rear speakers, so everything ehoes. As you could imagine this is a bit annoying. The speakers are logitech 640s. Never had this issue until i changed from my audigy to this onbaord sound. Any help would be greatly appreciated. Oh, and im not using the nvidia software, just windows default. Thanks
