Ok i figured you gurus might have the answer to my question. Google linked me here during my troubshooting search and i was like meh ill try it. SO, Heres my issue.

I turned on my Sony Reciever and started to play some music and randomly it has an echo. Ive played around looking for an echo option but no give. Im not sure of the model number if any of you could give me a hint on where it is maybe we can continue this trouble shooting further. Does anyone know how to get rid of the ever so annoying echo?
Also i tried more than just my computer with it i did my cd player and my dvd player and it still has the echo

I have also gone through all of the settings hall, concert, ect., ect.

I have also tried headphones and it still doesnt work

have you tried running it in a non dsp program like DOLBY 5.1 or DTS, or even proligic II

could be just the dsp modes like concert and all of them are adding in the echoe.
