I hate to say this to robert. I'm only getting sounds from my 5.1 system. center, right front, left back and bass... My left front, and my right back are not putting sound out. Also when I start windows 7 x64 it tells me that X-Fi CMSS 3D is conflicting with the bass program... I can assess the settings and manually set the Speaker to 5.1 but nothign works right.. I've tried all the different mods and no change. I've changed Default Format from 24bit 48000 Hz to 96000Hz and no change... weird.. But I have faith in your skills. I'm going to try some other ideas..
