Heres the link and thanks for any help.

Ok where to start. I first noticed this noise from the front right speaker while watching transformers dark of the moon on 4k blu ray at 1:30:31 in the movie.
Listen to Strange noise coming from new speaker by greg84 on #SoundCloud
I initially thought it was my new elac b5.2 speakers, but then I switched the two fronts and the noise stayed on the right side. That meant it had something to do with the channel and not the individual speaker.
Then as suggested on reddit I tried swapping the surrounds and front left and right with each other. Then play the part of the movie again in multi channel stereo to see if the sound moved to the surround. It did. After turning off the avr and reconnecting things the right way I noticed the strange sound was gone and thought it must have been a bad connection that got sorted by disconnecting and reconnecting the terminals. But the next day I tried watching the next transformers movie, age of extinction (just bought the set) and right in the beginning I noticed that I was hearing a different but equally disturbing noise coming from the top left front atmos speaker.
At that point I started to believe that maybe something is wrong with a specific amp in the avr and that unplugged it and and swapping the speakers at the terminals prompted the avr to reassign that amp to the new affected channel.
Then today I hooked up my old avr the onkyo tx-nr575 to test and the problem wasnt there. But again in order to do it I had to unplug, disconnect and reconnect the denon. Afterwards I tested the problem scene again and now the same noise I was hearing from the top front left speaker (the one that was different from the original front right) I'm hearing from both surrounds (more predominantly the right, but a bit on the left too).
Now unless I'm wrong about how the avr works then that would mean that my thought about having a bad amp that's being assigned to a different channel everytime I unplug the denon is false based on the fact that this time its 2 channels that are affected.
I only bought this receiver last month. It was a best buy market place seller who offers a 90 day warranty, so I'll be covered, but I dont like the idea of sending it away without knowing for sure that there's something wrong with it and not just my configuration.
