I know the title to this thread is a lot to live up to, but hear me out.
I ran XP for years with onboard sound--no problems. I have an ASUS board with built in RealTech HD, 5.1 configured with Logitech speakers. When I upgraded to Windows 7 Ultimate 64 (by upgrade, I mean complete fresh installation), everything works great, except the 5.1. I get two channel stereo, and that's it.
So, I bought a new SB X-Fi Titanium card, thinking that would solve the problem. It did not--I still have the exact same issue. I tried upgrading the drivers, downloading new ones from Creative, auto installing through windows, downloading the crazy tweaked support package 2.0 by danilel_k--all with the exact same results. I disabled the on board sound before I installed the SB card.
The strange part is, when I test the speakers in Creative Console or Windows, I get sound from left and right speaker. But out of Center, subwoofer, and rear channels, I get nothing--even though I can see the levels moving on Windows' volume mixer.
A buddy of mine suggested a fresh install (again) with the card already installed...but I'm skeptical of this solution, to say the least. Any ideas?
