I have a Sony Blu Ray player BDP-N460 connected to my Pioneer receiver using an HDMI cable. The player's audio settings are on the factory defaults and the firmware has been updated. Access to the internet is through a hard wired connection. When I use the Instant Watch feature, however, there is no sound on any title. The video stream works fine as does the instant queue, but no sound. The other streaming channels available through the Blu Ray player (Amazon on Demand, You Tube, etc) all have sound with no problem. I'm not sure how to fix this and would appreciate any suggestions.
