Buzzing sound from audio out to tv.

[nick101181]

I have a twinhan dvb-s card that I use to watch satellite with. I have the video going out to the tv and the audio is sent out to the tv thru a little adapter that splits the sound out to my pc speakers and to the tv. Well my problem is when I want to send sound out to my tv I get a buzzing sound when I try to turn it up loud. This also happens if I take the adapter out and just plug the sound going out to the tv. I have a 1/8 plug to rca adapter that connects the composite audio to the Audio in on my tv. I'm using gold plated RCA brand composite cables. Does anyone know why I'm getting this buzzing sound and how can I get rid of it? thanks

Sounds like a ground loop problem, you need a ground loop isolator. here is a link on what it looks like, http://www.radioshack.com/product.asp?catalog%5Fname=CTLG&product%5Fid=270-054 hope this helps.
