Just got a second video card to Crossfire, and now I'm having odd sound issues

Had a XFX Radeon HD 6770 in one slot, and below it was a SIIG 7.1 Channel C-Media chip sound card.

When the second XFX Radeon HD 6770 came in along with the crossfire bridge, I had to relocate the sound card to a different slot inbetween both video cards.

Now, anytime I go into something graphics intensive (video games), I get a nearly constant high pitch squelching/buzzing sound.

I have already uninstalled and reinstalled the sound card drivers to no avail.

Tried my onboard card, and it does NOT give this buzz, but I have two issues with this. First is that for some reason, my onboard sound card only streams sound to the left speaker. The right remains dead. Secondly, I dont wanna use onboard lower quality when I paid good money for a PCI card.

Ideas?
