Vista 64 All sound from right speaker only.

Ok, I've been fighting with this for a few weeks now off and on and hopefully someone will have an idea of what's going on.

As it stands, I'm getting all of my sound through the right speaker/headphone. The left channel sound is there, but it's extremely weak and is also coming through the right speaker/headphone. It's not exclusive to SWG either. Any sound that my system is trying to play, through any program is effected by this. The kicker is that it's happening with two different sets of speakers, two headsets and two different sound cards (one card, one on board). Nothing I've tried has been able to fix this.

I've checked the Balance settings in the Control Panel and that doesn't fix it. I've uninstalled the drivers for the sound card(s) and have tried running with only one installed and enabled, with both installed and enabled. Again, nothing's working that I can think of. I'd try the software for the sound cards but both can't be giving me the same exact error.



Any help would be appreciated. Relevant specs are as follows:

* Asus M2N32-SLI Delux WiFi edition
* Athlon 64 x2 Dual Core 5200+
* 8 GB RAM
* Asus Xonar D2X PCI-e sound card
* Window Vista 64 Home Premium
