Apologies if this has been asked already. I searched and didn't come up with anything.
I recently got a stereo surround sound system, with an optical port (SPDIF). I bought a 3rd party AV adapter (http://www.amazon.com/Catz-Xbox-360-Analog-Adapter-Headsets/dp/B004TEN2TO) that has an optical port on the back. When I attach that AV adapter to my Xbox 360, which already has an HDMI connection to my TV, it "steals" the video from the HDMI and the TV goes blank because obviously I don't have the cable connected to my TV, it's connected to the stereo. Is there any way to get the Xbox 360 to use the HDMI connection for video and the AV adapter connection for audio?
Thanks in advance.
