Recently build new rig. Specs:
Asus Rampage IV Extreme
G Skill Ripjaws Z 32gb
Samsung SSD PRO 256gb
MSI 7970 Crossfire
Put build together all went well. After a couple of days downloading drivers
began to test hardware. Started with GPU's. Installed amd 13.2 beta 7 drivers and installed Battlefield 3. Benchmarked gpu's with Heaven a few times at stock to ensure all is well. Played a few games of BF3 and Far Cry 3 all went well. Enabled Crossfire and benchmarked with heaven and then played BF3 and Far Cry 3. All went well. I am happy as can be.
Several days ago, I installed xbox 360 wireless controller. Installation went fine. Then I realize that I was not getting any sound coming from my Bose Companion 5 speakers. Did some digging and went to Device Manager/System Devices/High Definition Audio Controller had the dreaded yellow exclamation point indicating something is wrong. So, I backtracked and thought that the last thing I changed prior to PC working fine was installation of Xbox controller. So, I unplugged the dongle from the back of the i/o and voila...I have sound again. I didn't uninstall the xbox 360 controller from system just unplugged the dongle. I figured I might have a bum USB port. So I tried to a different USB and still NO sound. I then installed the USB dongle in the FRONT of the case and viola....I have sound and an xbox controller. However, I still have the issue the Audio controller conflict.
Also, now my crossfire is not working. It just seems to me that this high def audio controller conflict is the root cause. When I try to play in crossfire my monitors go black and monitors indicate no signal. I am at a lost here. Been trying for the past several days to rectify the problem. I have about another 10 days until my 30 day for return of any hardware lapsed. Here is the info in properties:
High Definition Audio Controller Properties
Device Type: System Devices
Location: PCI bus 3, device 0, function 1
This device cannot start. (Code 10)
Troubleshooting done so far: fresh install of amd 13.2 beta 7 drivers, tested each gpu seperately and also benchmarked each individually, changed crossfire bridge. Disabled crossfire and YES it does work when crossfire is disabled. Any help would be appreciated. I need to fix this conflict with audio controller. Thanks.
