Well neither Samsung nor Keydigital can figure out what is going on here. it seems the Isync processor receives and properly decodes the multi-channel audio signal, but does not encode it properly.
Once again, all audio goes through just fine over HDMI straight through to the LCD on HDMI, but if I run through the Isync, audio on SD channels only, nothing on all of the HD Channels.
NOTE: The Isync definitely gets the audio signal and properly outputs on all other formats (optical, coaxial, etc) it just will not encode properly or my LN-t5265F LCD simply cannot understand the encoding that the Isync puts the multi channel audio into.
there is something the processor is doing, agian coming straight from the Dish Box all data is fine.
