Hello, I am looking for advise on the problem for my setup. Items connected: LG Hometheatre system, Panasonic Plasma PX80, Procaster digibox, PS3, Sony wireless headset. I get sound and picture when watching digibox via hometheatre system, but when i have a connection between TV and digibox directly via HDMI without LG hoemtheatre system, i only get picture but no sound(neither from TV nor when i connect Sony wireless headset). Why i am doing this is to be able to plug my sony wireless headset to TV to watch recordings from digibox at night since my LG does not have a audio out option. I have tried 2 different HDMI cables(new from same shop) and same result. When i watch TV alone without LG hometheatre, sound is normal.(So TV speakers are not broken) Could you give some hints why this might be happening and what i should do next to try to get this fixed? Any help appreciated.
