I am not getting any sound from my rear speakers now with Media Center. It used to work fine. I tried the different settings in the Output section of the Playback options but none of them made a difference. I can load up Windows Media Player and the rear speakers work fine with it. I have an ASUS A7N8X Deluxe running Logitech Z-680's through the coax digital out. I have the Soundstorm settings correctly configured to digital out with 6 speakers.
