I heard that most of the sound drivers will not work properly on windows 7 ultimate edition. It will be better to use little lower version of driver in compatibility mode. If you have already done this before then assume that there is something wrong with your motherboard. Reset the Bios for restore some of the settings to default. You need to contact Samsung for further help about sound driver and S/PDIF issue.
