Does the Mini DisplayPort on this model support audio out?

I'm not sure what you mean. External speakers? I'm talking about hooking the Mac Mini up to an HDTV with built-in speakers. External speakers aren't part of the picture at all. Either I will get audio output via Mini DisplayPort, or I will have to get an adapter that pulls audio from the 1/8" or USB connector. I know Apple began supporting audio via MDP in more recent models and I'm trying to figure out if this specific mac was before or after that switch. Or if maybe there is a software patch that could enable this on older Macs?
