ok...... im no soundcard expert, it took me 4 days to properly get this card configured in my rig..
forget the disc drivers
, they wont run on ''7''
uninstall any ''creative'' software from your programs directory
reboot into ''safe mode'', then remove the soundcard drivers from the ''device manager''
let this run to desktop, it should then detect the add in PCI device, after that it should report ''creative SB X-Fi''.
again go through to desktop, the updater should then start.... install all programs from the updater....& then reboot if prompted.
i had to keep trying to install the drivers as the card seemed very intermittent (it was there one minute & gone the next
) until the drivers were installed.
what cables are you running for the sound ..?? (analogue.. red/white) (stereo headphone jack) (optical / digital / SPDIF / TOSlink)
the fist two run off the default sound device provided by windows, the last on will require you to manually switch the default device to SPDIF connection, might of changed when you upgraded the OS.
hope this helps in some way........
