Wrong Sound Blaster's PCI ID within Windows
- by pavian
I own Sound Blaster X-Fi Titanium, it was working with no problems under Linux or Windows 7. It's original PCI ID is 1102:000b but now I see different within MS Windows.
BIOS setup: 1102:000b
GNU/Linux: 1102:000b
Windows 7: 1102:000d
Windows 8: 1102:000d
In last days I'm experimenting with IOMMU PCI passthrough in Xen and I tried to pass this device to virtual Windows 7 and 8. Here I found this problem. I don't know if this is just coincidence or reason of my problem but it's wrong even in physical system.
Windows detects 1102:000d as a High Definition Audio sound device (I guess this name, I have localized Windows, but this is general name, the same was with Realtek HDA before drivers), it's playing but it's unstable (Windows speaker testing can crash that application) and I can't install Creative software. Used driver is hdaudio.sys.
Booting in BIOS or UEFI mode doesn't change anything. Nor CMOS clean. Someone met the same problem.
