This is my shot in the dark that someone may know a solution to my problem. I recently upgraded my system and wanted to try the onboard sound on my mobo. I have the A7N8X deluxe motherboard. The guy that built it said it worked with his analog speakers. I can't get it to work with analog headphones or my dolby digital speakers. I have boston accustics with surround sound and subwoofer. They all plug into the subwoofer and then have one central plug that normally plugs into the digital plug on my old sound blaster audigy. I tried EVERY HOLE (light blue, lime, pink and there was 2 others close to a SPDIF plugin) the plug would fit into for both my speakers and head phones. I Went in the nForce Control panel and turned on and off analog and digital speakers. I have turned on and off Dolby Encoding and Dolby surround. Anyone got any ideas?
