I have a LG plasma, do i need a optical digital audio out cord to use surround sound?

First off you will need to do a little bit of trouble shooting. Is the source (dvd, Blu-ray, cable box, etc...) plugged into the receiver with the standard red and white RCA cord or by an optical (toslink-fiber optic) or digital RCA (orange color code). If you are connected with a standard RCA cord then that it your problem and you need buy digital cord that both the source device and the receiver can accept (toslink - http://www.we-supply.com/browse.cfm/optical:-audio/2,779.html or Digital RCA). If the connection is now correct then you need to make your receiver do a "test-tone" to insure that a signal can be sent to every speaker (this is an internal test that just checks the speaker connections). If the tone tone operates correctly then you know the amplifier is functioning. If both of the mentioned things are now done and still not surround output then you need to check the internal menus on your source device and make sure that it does not require you to manual change a setting in the audio menu to make it work (i.e. change from 2-ch 44KHz to 5.1 or 7.1 or Dolby Digital or AC3 or some other surround sound protocol.)

You can't do that, this tv doesn't have RCA audio outputs. You will have to connect it using the Optical output - an optical cable is required.

Try running digital audio from the source - cable/sat - to the receiver. The fewer intervening connections and entities, the better. TV's are NOT considered sound sources for high end purposes or we wouldn't have Yamaha HTR-5860's and better speakers, would we?

you need a optical cable to play tvs sound in suround sound
but that depends on if your suround sound has a optical in

your tv does not have phono terminal for audio out

you may have to set the input value on the bravia for optical on the input from the cable box. sometimes there is more than one way for a particular input to receive an audio signal, you may have rca(red and white), a black or orange rca type for digital, and then the optical. i would suspect you have to tell the bravia how the sound is inputed into the bravia. also , just a thought.... on the cable box there should be a volume control on the front of the box........ make sure the cable box volume is ALL the way up (it is the preamp volume).

Are you running the sound directly from the DirecTV box to the Onkyo reciever? or is it routed through the TV first? Personally if you have it routed through the TV you are losing out on true 5.1 surround. To ge that you need to have the DirecTV box connected via optical or digital output (orange connector) to your Onkyo amplifier. If you need further assistance please email me at tvtek(at)msn.com

I went to the HDTV plasma manual. It stated the only way the digital optical audio output would work (from this TV) was to go to the menu, select audio and turn off the TV speakers. Basically, it had nothing to do with the technics receiver.

I can't imagine your setup. Box, tv and pc speakers?
Typical setup would be box, tv and some kind audio system with optical IN. Correct wiring would be connect box to tv via scart and connect optical cable from BOX to audio system. You have to go from box not from TV since scart connection doesn't carry audio signal. To have TV to output optical audio out you would have to connect it to box via hdmi.

me too i want to know

How can I get surround sound to work on my tv. When I pull up my menu and go to audio the SRS Trusurround XT is not in bold so I cant figure how to connect it so I can have the surround sound coming from the system and not from the tv. Please help.
