I just built a new itx box using my existing HD 6870 card and ASUS P8H610I R 2.0. Everything works fine except for the sound from the graphic card. In my previous rig it worked fine but in my new one the device manager in my Win7 gives Error Code 52. In fact, the sound came out from my Hd 6870 before crashing a couple of times. I installed the newest beta driver and even diabled my MB sound, but nothing works.

 PS. Oh, the Code 52 error has to do with AMD high definition audio device.
