Am I doing something wrong? I have connected my Macbook to my plasma TV and there is no sound. Help!?

Question

I have a Macbook and I went to Best Buy yesterday and the associate told me that I need the mini DVI to DVI connector, HDMI to DVI adaptor, and HDMI cable. I bought all of these items and plugged it all up when I got home. There is picture, but no sound. Am I doing something wrong?

Answer 1

you are doing nothing wrong, the cables and adpaters you have carry video only.  

You need another cable to connect audio.

mini stereo phono plug to dual RCA jacks
