I'm actually going through the same thing also. I've got the welfare cable package (13-ch.) and find myself watching more internet based tv.

There are a few possible permutations. More if you have a sound system being used in conjunction with your TV.

There are two parts you will need to address. The audio and the video.

On the laptop side there is the headphone jack for audio output and depending there can be (a) s-video, (b) VGA, or (c) DVI, or (d) displayport video output(s).

On the TV side you need to identify which audio inputs go with which video inputs so that when you pipe in the video you also have sound to go with it. For video, the TV typically has (a) s-video, (b) VGA), (c) HDMI, or (d) DVI. For audio there typically is corresponding RCA left/right receptacles.

For watching TV, VGA will give you the lowest quality picture, followed by s-video, followed by HDMI or DVI.

I do not know how "new" your laptop or TV is but I seem to recall the latest HDMI spec. supporting sound with the video. If such is true and if such is supported by both your TV and laptop, you may not need the additional audio cable.
