I have a Sony RDR HX750 DVD/HDD recorder hooked up via HDMI to the Onkyo 605. I currently only have two front Mission 780s and would like to also use the speakers in my Samsung plasma (PS42Q96HD) to help "center" the sound from my Onkyo. The issue I have is that I can't get the audio out of the TV speakers when playing back a DVD or when watching TV which has been looped through the Sony HX750 (NTL scart out to Sony. Sony to Onkyo via HDMI) I can get the TV speakers going when I playback recorded content off the Sony's HDD and also when watching TV directly from the NTL box (NTL has analog RCA to the Onkyo) I have tried all of the options in the Onkyo manual such as: DVD HDMI audio set to PCM, HDMI audio pass through set to yes on the Onkyo. Nothing seems to work. Is this just a config that isn't supported? They is something in the Onkyo manual that says that this config just might not work with some combinations of equipment. Any ideas or suggestions?
