Windows 7: No sound from SPDIF Xonar DS output to TV with Windows 7

No sound from SPDIF Xonar DS output to TV with Windows 7

Ok before I had Windows XP...have a Xonar DS Audio card with a SPDIF output going to my Nvidia 9500GT Video card...the video card is connected to my Yamaha V-867 Reciever via HDMI and then of course the reciever to the TV via HDMI.

So with XP it worked great. Had the video card set via the Nvidia control panel to Clone display so it'd just be two identicle displays on each monitor. Sound would be on my pc AND on my TV at the same time.
Well now I just upgraded to Windows 7 with the same connections. I only get sound on my PC speakers and NOT on my TV or Receiver speakers. The reciever shows it's not being fed any audio information. I have the audio set in my Xonar DS Center the same as it was in XP and nothing shows up on the equalizer when playing movies in Xonar DS. So it seems WMP is using the Xonar card to play audio of course...but not feeding it to the Xonar Center and not sending it out the SPDIF output. It's something with Windows 7 and the sound card?
Any help would be great...let me know if you need anymore info.

Ok so of course after posting this I semi figure it out. lol On my audio device settings it has 3 hardware options...1 SPDIF output device, then two speaker being the Xonar output and other being Realtek output device.

If I select Xonar output to the speakers I get sound on the reciever speakers (not on the TV though but not a big deal I guess) but no sound on the computer speakers. With the Realtek the opposite.

So NOW my question is how can I set this up to have sound on both without having to mess with options each time I want to watch a movie. Is there some way I can the Xonar card to just run everything?
