Help! Can't get Xfi Prelude to work with Vista 64 bit SP1

BuckoA51 · 3 Jun 2008 at 22:57

I recently upgraded my PC's processor and motherboard to an Intel Q6600 Quad Core CPU and Asus P5K motherboard from Overclockers. While building this PC I installed a dual boot system with Windows XP 32 bit Sp3 and Windows Vista 64 bit SP1. The Xfi Prelude works flawlessly under Windows XP, but I cannot get it to work at all under Windows Vista. When I install the drivers, Vista tells me that the installation failed, if I go to the device manager the Xfi Prelude has a red cross through it to show it is not working and the Device Manager also shows this information:-

"Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)"

I have tried three different driver versions and tried moving the card to another PCI slot but it makes no difference. I also tried disabling UAC and driver signing requirements, that made no difference either. I tried Auzentech's technical support but they just ignore me! Can anyone help?

Yes I've tried that multiple times

and yes I'm using RC5-1_Patch10

I'd be thinking IRQ conflict or something but the card works fine under XP... I really am at a loss as to what to try next

Thanks for your suggestions TheMagic1an...

Yeah tried a BIOS upgrade, no difference. At least I know now it's not a Vista SP1 problem.

RC5-1_Patch10 > Audio > Setup > setup.exe? - Yep that's what I clicked

Is it a fresh windows install? - Yes not done much with it really because I can't get my sound card working !

Vista and XP are installed on the same physical hard drive, but under different partitions and with a boot manager that sets them both to show up as C:\ drive.

Still no help from Auzentech ether!

Yep onboard sound is disabled and tried the card in two PCI slots.

Strange about Auzen's tech support because I e-mailed them a question about SPDIF mode when I first got the card and they replied within a few days! Wonder what's up with them?

They got back to me today and told me to do pretty much exactly the same as you told me, TheMagic1an

I tried again following their instructions exactly, didn't work. I e-mailed back and told them that did not work, no reply yet but I guess it's still pretty early over there. In the e-mail they sent me they said they would have a new driver out in a few days, so I might wait for that before I try a reinstall.

Oh and thanks for all your help everyone.
