I have recently purchased a Sony Bravia LED TV. I have an indoor antenna hooked directly to the TV. I have a optical audio cable going to my AV receiver (Yamaha HTR-5540). I am getting an audio delay in my speakers that progressively gets worse as time goes on. When I first turn on the system, it is hardley noticable. After a few minutes, if I have the sound on the TV on as well as the speakers - there is a clear echo. The TV speakers are in sync with the picture; but the audio from my receiver is delayed. I can temporarily make it better by switching the channel, and then turning it back. That sort of "resets" the signal to seem to process at the same time.
I am not getting a delay if I use my Wii. For now, I have audio and video (just the red, white and yellow) hooked to my receiver and am running the video back to my TV.
I called Sony, and they said because the sound on the speakers is working properly, it is an issue with my receiver. They said with a Sony receiver, there is a setting for the receiver to correct this delay. They suggested I call Yamaha to see if there is a similar setting on their sysytems.
I called Yamaha and they said I should not be getting a delay. They did not know of a setting with my particular model that woudl correct this delay. They suggested I "reset" my receiver and see if that helps. They lead me through the steps to do this and admitted it would be a long shot if that would actually help the problem. Well, the delay is still there. The Yamaha rep said it is likely an issue with the output on my TV.
Any ideas? Is there a setting on my Yamaha to correct this issue?
