I have a Sony KDE-50XS955 Plasma that I have connected to a Comcast DVR. The video is HDMI into the Sony from the DVR. The audio is from the DVR to a Yamaha YSP-800 digital sound processor. The audio from DVR to YSP is fibre optic. I also have a Yamaha sub-woofer connected from the YSP. Everything works and is nicely controlled by a Logitech Harmony remote. My problem is that I can't use the fibre connection into the Sony (and thence from the Sony to the YSP), I and don't understand why. Also, I can't get the Sony speakers to work with this arrangement, even if I have an additional audio connect from the the DVR to the Sony.
Can anyone help. I sure would appreciate input from all of you guys who know what's up. Sorry for what is be a low level of audiointelligence.
