Hopper3 Sling, Sony DH-510 amp. I have eliminated speakers and TV by swapping with others. When I pause a show on Dish no problem, but when I un-pause I hear a loud pop in the right channel only. (I switched speaker wires on amp and it changed to the other speaker. Also tried different HDMI cables ARC. Seems like it must be Hopper or amp. Can somebody please help me figure out which one?
