A loose connection could be arcing and making the noise, and could burn your house down. If the light is on a different breaker switch (fuse panel) than your HT, turn off the light breaker and see if the noise stops.
Modern high efficacy lighting has electronics, that can be very noisy if poorly designed or defective.
You don't want to filter out the noise; you want to fix the source of the noise.

Yes, LED bulbs I started using emit quite a bit of interference (EMI) due to the way they are built.. One thing the gov't never told you when they got rid of incandescent bulbs was that the electricity savings would be offset by the cost of buying better filters.

One thing the gov't never told you when they got rid of incandescent bulbs was that the electricity savings would be offset by the cost of buying better filters. Every bulb in my house are the LED which I got a deal on. I have no problems with noise at all. I would be looking at the circuit's making sure all the connectors are tight. Also check that the wires going into the breakers are still tight, I have seen the Mains which are aluminum get real loose after a time, depending on how big a draw your house uses. I have traces problems down to the outlets and switches. If you have noise it pays to look at everything.

OK. So last night after listening to a few CDs I started shuting down my system. The hiss and buzz were present. Through my mid range I could actually hear a country music song. Lyrics clear as a bell but very low volume. After about ten seconds it turned into distortion. Any help on this would be great.
And there is absolutely no way anyone in this house was listening to country music. Not knocking it just would never happen

I just did a little test. Its 6am. My house is dead quiet , no kids gaming, hvac system not running so I figured what the hell. I went and turned on my right channel and still the noise. BUT, when I disconnected the RCA from the back it got much louder. Almost as if the opening was now letting the amp receive the noise signal. Im stumped

Dear STUMPED. Electronics are awesome when that are working correctly but when something goes wrong especially something out of the ordinary it's a kicker. Maybe my stories can help. Food for thought. I will try to keep them brief.
First I had and have the Outlaw 7700 7 channel amplifier which operated flawlessly up to about two years ago when suddenly I began to heard a hum coming form my 7700. I was so frustrated I decided to take everything apart checking on connections as I reconnected, checking for lose fitting cables and cleaning. This was not a GROUND LOOP. Still I had the hum. I called Outlaw which at the time had GREAT customer service and spoke to Scott who was very helpful. Scott suggested that I acquire a volt meter and get some readings for him that he said could help him isolate the problem. In short the readings showed that I had DC current on an AC line that was causing the hum. NEVER heard of it. Still do not understand how that develops in a system or what it is and at this point I could care less since a recommended filter that I purchased worked from the first day I plugged it I to the wall.
Second problem was with a brand new pair of XPA1's from Emotiva. The LED lights were shooting across the front panels as soon as I turned them on causing a noise in my mains, even when the volume was not turned on. This problem developed after a couple of weeks ownership. The short story is this....after Emotiva tested my XPA's for two to three days on the workbench and found nothing wrong I was offered them back or two new XPA's. I decided on the NEW amplifiers. I received the new XPA1'S thank to Nick at Emotiva but I also purchased two heavy duty power cords from Emotiva. They offered very tight fittings both into my outlets and into the XPA's. The first day I received the XPA's I broke my back getting them DOWNSTAIRS into my dedicated room made the few connections and those bad boys are singing. AWESOME!
I guess what I am trying to say to you is check and double check all connections and receptacles. There could be a lose connection or bad cable in the mix.
Hope this at the very least gives you some ideas on how to solve your issue.
Keep us informed with your progression.
