Minidisplay port to HDMI adapter. Meritline.com has these on sale today for the adapter and a 6 foot cable for $6 shipped. I got mine from there a while back and haven't had any issues. To set up audio thru HDMI, go to Preferences > Sound > Output, then click on your tv that should be listed once hooked up. I just found out how to enable sound on it today and sure enough, it works.
