I have a Sony Bravia tv. I want to make the analog audio from any selected video source play through both the speakers in the tv,and through the overhead speakers that are wired to an Onkyo receiver. With audio firing from the Sony Bravia screen along with the overhead speakers I feel it would fill the bedroom nicely. It is all simple left right analog stereo audio. When I press volume up on the remote I want the tv speakers and the overhead speakers increase in volume simultaneously, and follow each other. The only way I know to do this is run the audio out from the selected video source into the receiver. This gives me the sound from the overhead speakers which are connected to speakers A on the Onkyo receiver. I then take the speakers B output on the Onkyo receiver and convert it to line level. I take this line level and feed it into the analog audio in of the selected video source on the Sony Bravia tv. Now when I adjust the audio level on the Onkyo receiver the speakers in the tv and the overhead speakers are following each other because the output of speakers A feeds the overhead speakers, and the output of speakers B (converted to line level) of the Onkyo receiver feeds the analog in of the selected video source selected on the SONY Bravia tv. I leave the tv speaker volume at a pre-set level. The problem is the tv speaker audio, and the overhead speaker audio are out of sync, and there is an echo. I do not know which is in the lead. The video is simple component video rgb. I can not use the analog audio out on the Sony Bravia because it is a fixed output and does not turn up the volume of the tv speakers. Why do I have this delay, and is there a way to fix it? Thank you for the help.

This is one of those things You Just Don't Do. Likely the television is adding an internal delay to compensate for internal video processing.

Daniel is right. You Just Don't Do It mostly because the TV works just fine as a TV and the Onkyo etc. works just fine as an A/V system, but the two things don't work identically.

It might be doable, but it might take outboard delay devices to synchronize the sound. Add $1000 just as a ballpark price for such a thing. If it's possible.

Then there's the issue of fidelity. Let's say your A/V system is high fidelity; that is, it accurately reproduces the sound you feed to it. When you then add the TV speakers, your system will no longer be high fidelity, because some limited range of frequencies will be added to an accurate set. This is a bit analogous to having great headphones, but then holding them a half inch off the ear for some reason or other.

This reminds me of analog days when someone would try to use the TV as their center speakers. The TV speakers sounded so so different from the main speakers! A car would drive left to right in a movie and you'd hear oooo-eeeee-oooo as the character of sound changed from high fi to poor to high fi again.
