Success is near. I had to do a couple things with Windows and AC3filter to get rid of the PCM 96 based on the above post. You need to go into "Playback Devices" and turn off 96 kHz under Supported Formats AND set the Advanced tab to 24 bit 48 kHz. You also need to set the PCM in AC3Filter to 24 bit 48 kHz.
I now have full access to all of the processors available on the AV receiver. It isn't 100% correct as the Level is too low which is making the amplifiers run hot. I also have to figure out the correct processor to use so that I'm not compounding the upmixing to 7.0 twice but I'm definitely close.
Another issue I'm starting to notice is that the volume level is actually fluttering after a few minutes of play and isn't constant anymore.

Reason: changed 24 kHz to 24 bit 48 kHz
