Hi, I have an LG 47LM670T. This has a Headphone out jack that sends all audio that would usually come out of the speakers to the headphones (obviously). This means it does not matter what source I'm using e.g. my Sky box on HDMI1 or my PS3 on HDMI 2 or even watching ordinary TV via the UHF aerial - I can hear all of them using my headphones via the headphone out jack. However, my wireless headphones sound rubbish using the headphone jack. My previous TV had RCA phono out which my wireless headphones loved. I'm thinking about getting a SPDIF Digital to Analog Audio Converter so I once again get a RCA phono out for my headphones. Question: Will all of the various SOURCES on my LG 47LM670T send audio to Digital Optical Out? e.g. I have an old video player connected to the SCART adapter, my Sky box is on HDMI1, my PS3 is on HDMI 2, I sometiems watch ordinary TV via the UHF aerial. The LG 47LM670T lets me change the audio out to PCM, which I've read might be required to do this. Does any one know for sure if all sources always output something to the SPDIF Digital out port? Thanks for any advice you can give me.
