I'm using MCE 2005. My soundcard is onboard, a realtek card with the latest drivers from the realtek site (A 3.74) Like I said after a fresh instaal it won't work. It worked before with the same hardware and software. Uninstalling and installing again won't solve it. The only thing that is changed since the last time is a bios update for my A8V deluxe board (1014.008 final)
