I have successfully connected my AlumMacBook to my LG TV - the picture is amazing. I did this through minidisplayport to dvi, then dvi to hdmi. I then bought a 3.5mm audio to RCA cable (pic attached). I get the audio working but not with the picture. I get the picture working, but not with the audio. I understand that the DVI to HDMI does not support sound, but where do I plug in my 3.5 to RCA to get it working with the sound? There are no RCA jacks next to my HDMI insert on the back of my tv. There are a lot of RCA, but none work while I am connected though the HDMI input?? How do I get the sound to play while I am watching the picture? Any ideas?
