Hi All

New to the whole HDTV and home theater thing. I've just bought a Samsung series 6. We dont have a proper AV amp so i'm playing around with what I have to hand. The PC has a logitech 2.1 system which got plumbed into the Audio out. All good except on every channel if I have the TV audio and the the "external" audio connected and running at the same time there is a horrible echo , probably a couple of hundre mS.

Is this normal.
