Ned help diagnosining Home A/V issue

Starting two days ago I started getting very loud random pops through my speakers. The sound then may or may not go out for a while but usually comes back on it own, sometimes I have to reset it. Occasionally, I will get an extremely loud noise (almost deafening) that last for about a second it starts out a low ringing sound and ends in a high pitched squeal. It kind of sounds like someone banged a gong. It doesn't happen while watching TV, but when watching Netflix through my smart DVD/Blue ray player. It didn't happen while watching a DVD. I am going to try Pandora an see if it happens then.

I need to figure out what is the cause. Is it on Netflix's end? HDMI cable or plug? My A/V receiver? I have no idea, and I have no idea on how to trace it. The problem is it's random. It may happen twice in ten minutes or once every hour.

Any thoughts?

Can you try switching the DVD player to another HDMI (or other) input and see if the problems goes away or persists?

In reply to DrBoost:

I'm going to try that, thanks.

You're welcome. I suspect you have a bad HDMI channel, or maybe a bad cable that's crossing the audio feedback loop.

In reply to DrBoost:

I thought that as well. But, I've been listening to pandora through the same box and same port for several hours and haven't had an issue. We also haven't had an issue when watching a DVD through the same port.

Here in a little while I'm going to put netflix back on and see if it still does it. If it does I will switch ports and see if it continues to happen.

At this point I'm leaning more towards a netflix issue.

Ahh. I misread them.
