Tried ground loop isolator but still getting static noise

[xecure]

Hi guys, I'm new here. I have a set of speakers that always has a static noise when i play something on the TV. When initially turning on the TV it does not make much of a static/hissing noise (maybe very slightly) but as soon as I put on netflix and play something the hissing starts. I've actually purchased a ground loop isolator to help fix this problem but still no luck. There is no static noise when using the speakers on the TV itself. Any idea what else might be wrong?

I found that the actual cable (if you are on cable) can cause the problem. I installed one on the line that usually connects to the TV and it solved my problems.

What type of connection from TV to stereo?

This does not sound like a ground loop (which is typically a buzz). This sounds like some other bit of noise. I'm thinking something to do with your digital to analog conversion and could well be as simple as a cable but it could also be noise radiated from one component to another nearby. Since this seems to have something to do with internet operation, I'd be looking on that side of things for issues. IIRC I'm using a Toslink between the TV and DAC; this allowed for complete electricl isolation between the TV and the rest of the system.
