So I've been trying for a few hours to get the drivers installed properly for my XFI Titanium HD - PCIE sound card and no luck. Whenever I reboot windows always has it with the default windows driver and I never get a driver installation confirmation popup during any of the pax installs. I've even tried the manual driver installer in the driver subfolder of the pax pack but that doesn't work either. Finally I've tried manually setting the driver from device manager and it says theres a hash file missing or corrupt and it cannot install the driver to the device. I have 2 audio devices in my device manager and these are their hardware IDS. HDAUDIO\FUNC_01&VEN_1002&DEV_AA01&SUBSYS_00AA0100&REV_1003 HDAUDIO\FUNC_01&VEN_1002&DEV_AA01&SUBSYS_00AA0100 HDAUDIO\FUNC_01&VEN_1102&DEV_000D&SUBSYS_11020043&REV_1000 HDAUDIO\FUNC_01&VEN_1102&DEV_000D&SUBSYS_11020043 - I had the drivers working previously but apparently running the AMD Cleanup utility for my video card drivers has removed the pax drivers I had installed before. I am running windows 8.1 pro as well and have tried these packages...
