Hi all:

I am trying to watch movies on my MacBook on my HDTV. I get video, but no audio.

I have the appropriate mini DVI to HDMI video adapter and I get beautiful video on my relatively new LG 40" HDTV. I also have the 3.5 mm to RCA cable from the headphone jack to the red/white AV IN on the HDTV directly adjacent to the HDMI on the HDTV. No sound.


There is nothing in the LG user guide that talks about connecting a computer to the tv. Also, there is nothing on the audio menu on the tv that I can change to make any difference, nor is there anything that I can see in System Preferences > Sound that I can change to make a difference. I THINK I have tried everything. I even tried the other three HDMI ports.

Is this a OS issue? I am running OS X Lion 10.7.5

Thanks for any help you can give me.

No problem. Any help, whenever I can get it, would be great.

Hope this helps.

Thanks so much!

See page 27 of the owner's manual - DVI to HDMI connection - available here.

You must use those connections.

You will use the same video cable you already have.

The audio port on the TV is the same as the port on your Mac - stereo 3.5mm ( aka mini-plug) on both ends.
