Awhile back I had an electrical surge that pretty much killed everything in my PC. I got a better PSU put in, two new gig sticks of DDR2, and a GeForce 8500. But the main thing I had to replace was the motherboard - an intel D945GPM. I was able to salvage the processor from my old one and put some new thermal paste on it and made sure the fan/heat sink was in place. Everything seemed to be working fine, albeit a little slower due to my video card (another thing I need help with) except for one thing. My new motherboard will not recognize my home theater system as 5.1 one anymore. When I go into Intel Audio Studio it says it is a PCM stereo under digital input so I only have the two channels. I can still make it play through all my speakers if I mess with my stereo's console but it sounds absolutely horrible. I don't know what the problem is, because before the switch I could control everything (the individual speaker levels with EQ and everything) through Intel Audio Studio. Now it doesn't make a difference what I do in it, and the windows mixer doesn't seem to make a difference either. I've tried downloading all different kinds of drivers for my mobo from Intel and updated version of IAS but nothing seems to work. Please help me with this, because I'd really like to have my surround sound back. Also, for reference it's hooked up with a coaxial cable and the system itself is a Panasonic SA-HT05. It has DRTS and Prologic II and works absolutely fine.
