Hello, I purchased a 27in iMac last week! I also bought an Minidisplay port to HDMI adapter WITH SOUND from Monoprice. Unfortunately, I cannot get sound to come out of my TV no matter what I try. I have tried changing the resolution of the screen, changing the sound setting to the HDMI plug (it recognizes it...), but nothing seems to work. The sound always comes though the imac speakers, no matter what options I choose. Does anyone have any insight?
