Issue Details

I have 2 AMD 7870's in crossfire.  If I use version 12 of the Catalyst software, I have no issues at all. When I install version 13.1 and the latest beta, one of the HD Audio controllers fails to load.  It shows in the device maanger with a yellow exclamantion mark.

This is some of the info that it shows:

This device cannot start. (Code 10){Operation Failed}The requested operation was unsuccessful.

DevicePCI\VEN_1002&DEV_AAB0&SUBSYS_AAB01458&REV_00\6&1bf4f655&0&01400008 was configured.

Driver Name: hdaudbus.inf

There are 3 HD Audio Contollers in the device manager in total, the other 2 load fine and have different VEN id's, the one that does not load shares the same vendor ID as one of the ones that load - I am guessing that they are both AMD ones as I have 2 cards and one on my motherboard.

No viruses - no other issues - only this issue when I change from version 12 to 13 of the Catalyst drivers.  If I go back to version 12 ALL HD Audio Devices load correctly and do not show an error in the device manager.
