My soundblaster 5.1 isn't supported for vista by creative, so I can't get drivers for it. So, I am using my integrated Realtek ALC850 that's in my A8N SLI-SE. I got it working and the sound quality is fine, although noticeably worse than than the Live 5.1. The only problem is only the left and right speakers of my 5.1 surround speakers get sound. I used the configuration utility to set it to use the mic and line in ports for center and sub, and rear speakers, but it still only powers the front left and front right. I can get the others to work by using matrix mode on the speakers, but the quality isn't all that great. Anyone know what I should do?
