Hi guys..i have problem with my realtek hd driver... i have 5.1 sound system, and when i install appropriate driver for windows 7 (downloaded the from realtek website) everything works fine, and windows recognizes all speakers and i even test them, so they work fine.. BUT when i turn on winamp or WMP, i can only hear two front speakers. I tried configuing winamps output settings, and reinstalling driver, nothing works... can someone help?
