I cant install my audio drivers in windows 7(8 posts)
Do you have any signs of errors in the sound area of Device Manager?
Are you doing your uninstall/re-install attempts through Device Manager or some other method?
I use Realtek onboard sound and cannot recall any particular difficulties with the control panel.
Do you have Realtek entries in the regular "sound" control panel?
Cougar-Extreme is a reseller not a manufacturer. You will need to check your specs or use something like Belarc Advisor like Xhi suggest. Judging by your screen shots Your board is probably from ASRock, since I see ASR listed in your drives. Figure out what board you got and go to the board makers website for drivers.
