I'm fairly certain my audio card (integrated) is Realtek ALC883, it's part of the GA-965P-DS3 Rev 3.3 board. Anyways, for some reason, the sound card is convinced that my subwoofer is ...well, I'm not sure what. For starters, when I raise the rear sound volume, the subwoofer volume rises. As for right now, I have rear, center, and subwoofer volumes at zero, and I have turned the subwoofer control knob to zero, but it still thunders occasionally. Any ideas how I make the subwoofer obey its own control knob and the subwoofer volume line in Windows?
