Use the map to loop through the optical output Dolby Digital and DTS to my AVR. Had the driver on the CD problems. On the internet there but one of work with my Windows 7 HP 64bit. But one must look for the chipset: CM6206. Simply Google "cm6206 driver" Enter. First Page. With everything works fine. Possibly even take after installing the tray icon from the startup. Is very buggy and flooded when I open it immediately my 8GB memory. There is no need for the function, The analog outputs I have not tested. Digital everything good.
