Since adding a new Mitsubishi 1080P DLP TV (WD-73734) to my older 5.1 Sony A/V Recvr surround system, watching TV (Comcast cable w/ no box), sometimes the voices do not sync with the lips. I read somewhere of a lag in audio??
My Cable TV coax from wall/source goes to TV.
'Digital Audio Out' from HDTV to 'Digital Audio In' on A/V Rcvr.
Is audio being delayed by processing to 5.1 thru my A/V Rcvr? Any way to work around this. Weird that does not (seem to) happen all the time.
Thanks in advance for any insights.
PS. I can't afford to upgrade A/V Rcvr, but if a new one had HDMI, would THAT change this phenomenon? |

Unfortunately there is no work around. Unless your Sony has a delay feature, then you might want to look at newer receivers. If you can move on from Sony, do so. |

The cheapest solution may be to get a cable box. |

Berny,
So the audio arrives (thru TV, to A/VR, to spkrs) 'faster' than video signal connected directly to TV, and it needs to be delayed?
My Sony has 'reverberation' timing adjustments, but no simple delay feature.

Dave,
Is there a difference between the audio of the Sony Receiver as compared to the TV's speakers? |

Jim,
Extreme difference.
TV has (2) 10W, 2.25" x 5.5" speakers (lousy sound).
A/VR: 5.1 Dolby Surround with Klipsch Cornwall Mains (16" woofers), good Center, good in wall mounted Rears, 2 powered subs, all tuned to listening position. |

Sorry, I need to be more specific, I mean with the delay. What I suspect is that the delay is caused by the TV. If there is a difference between the TIMING between the TV speakers and the Receiver, especially (or only) while viewing a non HD source, where the Receiver is behind the TV, the delay is caused by upconverting the audio to digital. This could be solved by taking the analog signal out of the TV but would be a pain to switch when you switched to a channel in HD. A cable box would be the solution with the video going to the TV and the audio going to your receiver. |

My Onkyo has an a/v sync adjustment for each input that allows you to see the video from the source while tuning it. |

Actually, I have not noticed the 'voice out of sync' lately (strange).
One thing I have never been clear on. I run only audio into my A/VR and video directly to TV from sources. Is this a problem, and why?
Luckily, my new TV's remote, has the ability to 'switch inputs' on the A/VR when I switch inputs on the TV from TV, DVD, VCR. |

I have never had a problem doing it that way. In fact I think I have noticed this problem more when using the switching thru the AVR. |

"noticed this problem when using the switching thru the AVR"
Jeff,
Your above statement refers to the 'video' switching, right? I assume audio switching 'has no choice' but to go thru A/VR to get your 5.1 (or whatever) surround.
Thanks, Dave |

Yes, you asked about using the video directly from the source to the TV. I was just saying that I have had better results that way. The only time i have ever seen this problem is when using the avr to switch sound and video. Anyone, correct me if I am wrong but I think this may have something to do with the extra processing the AVR has to do before the signal is delivered to the TV. Again, this is not a problem for me because my Onkyo TX-SR605 has an adjustment to compensate for this. It is called a/v sync and can be adjusted for each input. |
