Hi all, As the title, I have that receiver, and when using it, randomly it makes reasonably high pitched clicks. It could be 1 every now and then, or 5/6 then a gap and then a few more.... Any idea what this could be? Excessive heat making things move and click? audio quality is not affected. It does it using Sky, or my TV via ARC, so it doesn't appear to be limited to a single device. Which leads me to believe its the receiver.
