you can use a simple cable to go from DVI to HDMI on the TV.

Not all DVI-to-HDMI adapter cables are identical in the way they handle the conversion. Some adapter cables are made to handle the audio that's lacking, while others aren't. Some DVI output ports don't have audio at all, while others do. In theory a DVI-to-HDMI adapter cable should be a straightforward solution. In practice this can be a very frustrating experience if you have the wrong combination of DVI output port and DVI-to-HDMI adapter cable. If you get lucky and have the right combination it will be "simple" (plug & play), but I think it's likely to be more complicated in most circumstances, and nearly impossible in some circumstances.

I lean toward the "keep it simple" method which in this case would be to use the VGA input port on the HDTV, and either a VGA output port on the Mac, combined with a standard VGA cable. If the Mac doesn't have a VGA output port, use a DVI-to-VGA adapter to provide a VGA output port. Then handle the audio with a standard 3.5mm mini jack audio patch cable from the Mac speaker output to the HDTV audio input jack or Mic jack. This is about as foolproof as possible, but there still is the issue of matching the video card output resolution/refresh to the acceptable inputs of the HDTV.
