System - Windows 7 Professional 64 bit
Motherboard - Gigabyte GA-880GMA-UD2H
Sound - Realtek on motherboard
Speakers - Altec AVS300
My problem is that I cannot figure out how to get sound playing from my left speaker and also the subwoofer. It worked fine on my previous Win XP system.
As far as I can tell only the right speaker works.
The Altec systen has 2 speakers and a subwoofer with 1 leads that plugs into the motherboard. I used the Green connector on the back of the motherboard.
The realtek HD Audio Manager does not a a 2 speaker plus subwoofer configuration.
The 2.1 speakers you've got are actually stereo speakers with a separate speaker for the lower frequencies, if you chose the stereo option in the driver you should get sound through all of the speakers if not there is something wrong with something. You could try and plug the speakers into an mp3 player see if it gives sound through all of the speakers if that works try a headphone on your soundcard, if that works try reinstalling the driver.
