I have an LG all in one home theatre system, LCD TV and Direct TV satellite box. It is all hooked up and working fine except I only hear the sound through the speakers when playing a dvd or radio. The sound only plays through the TV when I am watching satellite. I hooked a fiber optic cable from the TV to the AV receiver, but still no sound through the speakers.

OK. For all you regular Joe's like me here's the fix--plain and simple! I have Dish Networks HD receiver, an LG Home Theater System (LHB953) and an LG HD Television - although I suspect this applies for most LG TV-to-LG Audio Systems used in combination with a HD TV). My problem lied within the LG to LG setting known as SIMPLINK which tries to "auto-configure" everything between LG to LG devices.

Do this to make your HD TV (using Dish/DirecTV) play it's HD video display from the satellite provider but play the audio over the LG surround sound speakers:

1. Plug a HDMI cable from your satelite receiver's set-top-box to your HD TV. This will carry your HD "video" ONLY. Click "Input" on the TV remote until the HD video signal shows your desired TV channel from your satellite provider.

2. Plug an HD Optical cable (the one with the red laser) from your LG HTS (Home Theater System) to your satellite box. This will carry your HD "audio" ONLY.

3. This is the magic everyone seems to be overlooking. On the LG TV remote, go into the menu options and disable SIMPLINK by setting SIMPLINK=OFF. This feature allows the video and audio signals to be split over 2 different ports: HD video goes over the HDMI cable and the audio to go over the HD Optical cable.

Hope this helps!

From which connectors to which on the TV (what brand/model?) did you run the optical cable?

Please clarify: "The sound only plays through the TV when I am watching satellite". Do you WANT the sound to come from the TV; or do you want to hear the TV program audio from your LG??

Which way are you envisioning audio to flow - TV to receiver or receiver to TV? There is NO audio output from the LG to anything. Think of a TV (monitor) as simply that which produces the picture. The best sound-handling and -sourcing will be at the receiver.

Generally, most externally-sourced TV watching originates with a cable box or satellite. I believe you have the satellite function figured out. Cable will be similar, but you may not have the required available inputs. There will probably be some sort of analog or digital audio output on the cable box. Connect it to the Aux In or appropriate available Digital In on the receiver as applicable. Select the appropriate input on the LG when watching TV.

Hint: if you have to share the only Coaxial Digital Audio Input on the LG, that is possible. Get an RCA splitter and run it to both sources. Just make sure the one you're NOT watching/listening to is turned off to avoid having an excessively verbose digital conversation going on with the receiver or between the two digital sources. I do this in my system.
