Loud buzzing sound from surround sound in tt

New owner of a 2014 Stealth and noticed buzzing sound when I am watching tv or DVD with the surround sound hooked up. Anyone else have this issue?

I have it too. Drives me nuts. I think buzzing in the background is usually a grounding issue, but I haven't bothered to investigate yet.

Do you have LED lights? It's a known problem that a lot of them emit RFI and will interfere with television and radio signals.........but not sure if they cause the buzzing.

If you do have LED lights, I guess the easy test is to make sure they are turned off and see if the buzzing continues.

I DO have LEDs, but I'm sure they're not the issue. The buzz is only there while using AUX, and it occurs with lights off as well.

The led lights have no affect in the buzzing. Still getting the buzzing while watching DVD in my trailer with surround sound on.

Is the buzzing coming through only the surround sound speakers, or is it also coming though the TV speakers when raising and lower each separately. Is it all the speakers in the surround sound system or is just one speaker? You have to able to troubleshoot and diagnose where the problem is. I found that FR used really cheap speakers in my Work and Play Toy Hauler and if I crank up the volume they sound terrible and or vibrate.

The buzzing is coming from both of the inside surround sound speakers. The stereo system is the kicker stereo upgrade factory by FR

On my Solera the problem was similar - when playing TV or DVD movie sound through house speakers using in-dash Magnadyne as DVD source and as house sound amp. I used Stinger ground loop isolators ( Stinger SGN20 Ground Loop Isolator:Amazon:Electronics) attached to back of TV. I also had to use an isolator on the composite video feed. Result was quite good. Good luck!

Here's the link to the isolator. Axxess AX AGL610 Electronic RCA Ground Loop Isolator Noise Filter 2 Channel | eBay

It just plugs into the speaker wires.

The speaker wires plug into one side of the isolator and the other side plugs into the sound bar.

I would try it on the audio wires between the DVD player and audio system first. I'm surprised you can have a ground loop with speakers. (They're usually floating, or at least have a common ground.) Maybe that's what the "Noise Filter" part of that thing is doing...killing the low end.

I don't know how or why it works but it worked for me and got rid of that annoying buzz.

So I guess I will have to take out the stereo head unit to access the RCA wires?
