How do I connect the Home Theatre System so that I can hear surround sound from the TV instead of through the TV speakers?

R U getting 'feedback'?i.e. if the speakers on the TV and your external speakers are pushing the same 'sound' towards each other there could be feedback.

I assume you mean the TV sound only comes out of the TV. THAT would involve internal audio controls at the TV.

Why don't you just connect the TV-related audio directly from each source to the DAV instead of through the TV, which adds NOTHING to the sound quality and may even degrade or limit it.

Connect RCA Red-White audio cable to INPUT of DAV-HDX500 and hook it to TV AUDIO OUT pins at back of TV.
Now select INPUT in DAV-HDX500 to get TV sound in Sony system speakers.

Please check at rear of TV for Digital Optical IN port as home theater should have optical out port at rear. If you got any optical in port in TV, just connect optical wire between TV and home theater.

2nd option is check Line Out pins at rear of home theater system, if found, hook red-white RCA cable there and put it to same input in TV where you hooked Video (composite or component) cable.

Let me know the results to help you more.

that is possible
the home theater has so many in puts on your dvd and out puts.
there is a way
1 you can buy a vedio/audio converted to rf signals, this will mean both signals entering tv using rf.
2 get your vedio out from dvd and audio out, feed that to a converter, vedio in and audio in okey

The fiber optic port on back on your bravia tv is only for when your using a over the air antenna and watching local atsc channels in your local market. You need to run the fiber optic from your hd cablebox if it has one or your hd sat box if it has one. If you don't have a set top box with the fiberoptic port on it you can use a digital coax cable from the cable or sat box to sound system. The only other way to get sound if you don't have a cable or sat box is to run the red and white rca audio cable from the tv to the sound system and got to the audio setup on tv and turn the tv speakers off and you might have to adjust the audio to fixed instead of variable.

It looks like all you'll need to do is hook up audio out from DirecTV to audio in on the surround sound system. Sony has an interesting hookup recommendation guide on the product support site:

That should give you the connection options. The short answer, though, is to connect the best audio out from DirecTV to an audio in on the surround sound and then choose that option in the surround sound system when you want to watch TV.

In short, the answer is: Hook up all three to each other. I have a Samsung DLP HDTV, and I was trying to hook up a Sony DAV-HDX500 home-theater system and a Comcast HD set-top box, but I found that the Sony user guide is helpful only for setting up the speakers. Most of what it had to say about HDMI and getting the TV sound or cable sound to go through the speaker system was wrong (or, at least, it didn't work for me). So, here's what I did. I connected Component video cables (Y/Pb/Pr out) from the Cable box to the TV (Y/Pb/Pr in), audio cables from the Cable box (audio out) to the Sony system ("SAT/Cable" audio in), and an HDMI cable from the Sony system (HDMI out) to the TV (HDMI in). This allows me to 1) watch DVDs with surround sound through the TV's HDMI source (when the "DVD" format is selected on the Sony system), 2) watch cable with surround sound through the TV's Component source (when the "SAT/Cable" format is selected on the Sony system), and 3) watch cable WITHOUT the surround sound, as I did before I ever had the Sony system. One item of note: When watching a non-HD channel with the surrond sound on, the audio is slightly out of synch with the video; thankfully, there's no such problem on HD channels. Anyway, I hope this helps. It drove me crazy for two days straight!

Did you try to connect AUDIO OUT from your TV to AUDIO IN on your package?
