M_Bruno,

Thanks for the help. What I am using is the new Multimedia PC from HP and Microsoft.
[Link: microsoft.com]

It has one Coaxial digital output. This is for playing DD and DTS DVD's. I also use the PC for playing my MP3's. I use my Denon's Multiroom feature to distribute audio through my whole house. My problem is that the Denon will NOT pass a Digital audio source to the Multiroom output. I need both Digital and Analog to take full advantage. Switching the sound card back and forth is a nightmare and not practical.

I also thought about adding a second sound card. I believe the Windows Media Player would have problems recognizing wich sound card to use?
