Samsung 6350 audio problems

[Jerryhawthorne]

I hope some of you can help me, I replaced an aging Toshiba DLP 65 inch with a new Samsung 65" LED. I'm having audio problems. I knew the TV sound was far short of spectacular.
To start out, my old Toshiba was hooked up to my two inputs (Dish and Blueray DVD) with HDMI. Also I brought both boxes out with their optical out to the two optical ins on the Denon. If I wanted good sound, I would turn the TV volume down and turn on the Denon and select the input for which I was using. The Denon would select the proper sound field for the program material being received. Generally Dolby 5.1 which works great with my speaker system, providing nice surround sound. Some source material would go to Pro Logic, not so great.
I was happy. The new TV has an optical audio out, being the dull knife on the table I thought great. A single output of what is going to the TV and I won't have to change inputs if I want to turn on the Denon. Well, no nice Dolby, only PL and I would say no real surround out of that puppy.
A little checking and both optical inputs work on the Denon and both optical lines if I hook them up to the two boxes (removing the one from the TV to use) show a nice red light at the output end but no sound directly out of the Denon, it is like the new TV hook up killed the optical out of Dish and DVR.
Any ideas out there? Nice TV but can't seem to use my surround system.
