Does anyone know of any way I can set up 5.1 surround sound using a Realtek on-board soundchip? I want it to use all 6 (front l/r, back l/r, center, and subwoofer). It does this by changing the Line Out and Microphone jacks into outputs, but it doesn't work in Linux.
Also, should I get it working, is there any way to use the "Center" channel as a 2nd subwoofer channel? I'm cheap and don't have real surround sound speakers, so I want to use an old boombox for a subwoofer, but it has 2 channels.
