Long time reader, seldom poster. I have a Yamaha DSP-A1 Amp. Recently (Nov 2007) I purchased a Toshiba HDDVD XA2 player from Robert at Value Electronics. Ever since I connected the player to the Amp via Optical for sound I get a real bad echo.
I previously had a Sony DVP-7700 connected to the DVD inputs using optical for sound, and had no problems. When connected the XA2 to the DVD inputs, I moved the Sony 7700 to the AUX or Video inputs and it also has echo now as well. This problem perplexes me.
Here is a bit of background on my setup - I have a Sony 40XBR5 TV, and have all DVD & video devices (RePlayTV's) connected to the TV (Video & Sound) and the AMP (Sound only) indepentantly. I do this for my family, they don't want to learn how everything works and just want to be able to watch video content by turning on the TV and selecting the proper video circuit. So thats why I have all things connected to both.
More specifically, The XA2 DVD Player is connected to the TV via HDMI and then to the Amp via Optical. The Sony DVD is connected to the TV via Compenent (RGB) Video and to the Amp via Optical.
I have tried the following things with no luck at getting rid of the echo chamber effect:
1.) Turn Amp on first, then turn on TV, then turn on DVD player
2.) Turn TV on first, then turn on AMP, then turn on DVD player
3.) Turn DVD on first, then turn on TV, then turn on AMP
4.) Turn DVD on first, then turn on AMP, then turn on TV
5.) Turn TV on first, then turn on DVD, then turn on Amp
I think I have tried every combination of turning things on to no avail. Once in a great while I can get the sound to play normally, but can't repeat it. Even after I write down what I did to get it to play with no echo, I can't repeat it by taking the same steps.
Is it possible that I have a problem with my Amp? I hope not. I was trying to keep this Amp for a few more years before upgrading.
Thanks to all who may have any advice to offer.
