I have a HP notebook that i am trying to link to my LG TV. i have linked via VGA from notebook to TV, this allows me to see the screen on the TV. My issue is with teh sound, i queried with PC World re the audio. they advised I would need 3.5 jack from notebook to TV, this has not worked. Any ideas ? I do have HDMI slots at the back of the Tv but not on the notebook.
