This only happens on those two movies?Finally had time to check out my weird ATMOS noise. Just easier to take the positive wires off the speakers then from off the back of the receiver and only have the atoms speakers on. Now I can crank up the system and better isolate this noise. I recorded the isolated sounds and one scenario it seems like when atoms channel is called it makes a clicking noise almost like if the atmos amp is turning on making the sound (with no noise) and then clicking off noise when atoms is no longer needed. The second is when atmos isn't playing the noise is always on until atoms and then once atmos is done the noise returns.
I called Yamaha and they asked me to push the pure direct button that bypasses everything enhanced audio and only comes from the source playing. It reduced it a tad but was still doing the same thing. I tried a boatload of movies with atmos and Midway was fine and worked great and a couple of others I had both ripped and from the 4k disc. Connected the receiver to a different outlet etc but still the same. I know it is a lot to ask for someone to unplug their speakers except for atmos to see if you also experience so the last resort Yamaha said I will then need to send it back in. Just sucks.
Have a listen to two sample atmos tracks the first one from Hobbs & Shaw where you can hear when atmos is presented to the speakers a pop before and after and the second one from my worst sounding movie which is Rogue Nation where a constant noise when no atmos is being played but fine when atoms sound is present.
