I have installed a creative X-Fi titanium (regular, not fatality) on my windows 7 machine.
I installed the latest dirvers ( XFTI_PCDRV_LB_2_17_0007 )
The system seems to recognize the sound blaster alright (it's listed as "Creative SB X-Fi" in the device manager)
Sound is coming out of the card alright (at least the optical out, which is the one I have linked to my Sound system)
But, when I try to launch the Creative control panel, it says the supported audio device is not detected on my system - the application will close (free translation from the french)
I am having exactly the same problem. Have not been able to find a solution yet. I have an NEW HTPC with an X-fi fatal1ty, under Windows 7 Ultimate. Sound is ok, but cant access the Creative Audio Control panel.
I first installed the drivers that came on the CD-ROM, and only then did I let the auto-updater take me to the latest version.
In other words: I got this problem because my first move was to rush to Creative's website and download the latest drivers. (This si usually the sensible thing to do, but it brings doom in this particular case).
Thanks the problem I have is that the drivers in the CD are not for windows 7, and im doing a clean install with windows 7. Ive done the installation twice, unfortunately both times with the same result. Im thinking that Ill just have to live without the advanced preferences from the creative audio control. Thanks anyway for the assistance!!
