I have a BRDVD and HD cable box hooked up through a Samsung audio receiver via HDMI cables which works fine. When I try to use the TV internet feature I get no audio. I am using an optical cable from the TV out to the optic in to the receiver. The only way to get audio is to turn off the receiver and use the TV speakers which defeats the purpose of home theater. I have VUDU and ZULU and want to be able to run through the audio receiver. Any thoughts?
