Asus xonar DG, with buzzing and crackling

Hey guys..

Ive resently purchased a Asus Xonar DG, as i was told its a decent addon for my desktop computer. Ive been more than happy with this card (running Foobar2000, wasapi, FA-003 clone) and it sounds just fine.. Well that was untill i started running any 3d game at the same time. Ive tried just about every driver version there is (unified and all), tightened all the screws and all in my desktop, disabling all extra output and input devices, onboard soundcard disabled in bios but i just cant make it stop buzzing and crackling. Ive been reading up on this on different forums but havent realy been able to find a solution to my problem.. Now you guys are my last step before returning this card for good. I never realy play any game with sound on because i listen to music while i play, and now that aint possible (well ya it is but with that annoying buzzing and crackling sound). If someone got the golden egg to solve this out ill be very happy..

Best regards, Thomas

No crackling or buzzing with onboard sound, got phones plugged right into the soundcard and the soundcard is at the buttom and the graphic card as far away as it can get (top PCIe slot)
 

super.. just checked with onboard soundcard again.. and its still there.. guess im just not aloved to play games on my PC anymore.. bummer.. when my graphic card is working with a 3d game it goes nuts.. maybe a USB DAC / amp will do the trick.. kinda expensive test though.
 

Ive finaly found a solution.. every post on the net refers to interference from the grafic card.. now ive removed the bracket from the soundcard and "mounted" it with some none conductive material and the buzzing is all gone.. I had what everyone else on the net had with the buzzing in 3d games, buzzing while scrolling and buzzing when typing.. its all gone and im happy =) !!
