I've plugged my sound and video through the tv via RCA jacks. I have some movies on my computer that require me to have the volume high to hear them. When I play them I get a buzzing sound. Any ideas as to what is causing it and what I can do about. Thanks
could be many things but cheap RCA cables would cause this. When I first bought a surround system for the TV I had it connected with RCA cables that cost me lees than £5. I could not get the surround sound right & had buzzing at high volumes. I spent about £30 on some half decent cables & the surround sound came to life & the buzzing went I think due to better screened cables.
