You might try starting in Safe mode , going to Device Manager and making sure you only have one sound card listed...remove them all if you find more than one
Did you have to install the drivers from a disk, or did windows find them automatically?
Sometimes removing the sound card from device manager then restarting, will "freshen up" the drivers
