I have a Logitech x5400 5.1 surround system. It plugs in through 3 standard 3.5mm stereo plugs. My motherboard is an ASUS M2N-E SLI, and it has plugs for full 7.1 support. The audio chipset I'm using is integrated into the motherboard, it's a C-Media 6501 and my driver version is 5.12.08.1701. I'm using the 18.104.22.168 version of the configuration panel. IT also says my Audio Controller is "Standard OpenHCD SB Host Controller." The problem I'm having is I can't set up surround sound. I recently reinstalled Vista Ultimate x64 (on my old installation I had this working,) and since then it hasn't wanted to work. Before I think I had my audio output set to 7.1 for some reason, but it worked through all 5 speakers and the sub and sounded great. Thing is I can't remember if I set it to 7.1 in the C-Media configuration panel or the default Windows sound configuration, I've tried both though and neither want to work. Please, if someone could help me get this working I'd be very thankful. If you need more information just let me know.
