Doesn't support sound on 2012 mac mini, only video.
on February 13, 2015
I must say I am very disappointed. I have a 2012 mac mini and I had decided to upgrade from a 720p TV to 4K UHD. In preparation for that move I had ordered this mini dp to HDMI adapter to be able to work at 4K resolution. 2012 mac mini is on the official list of the devices from Apple that support both video and audio through mini dp port. The specs for this adapter also promise full audio support. My 4K TV is still on its way so I plugged it into a mini dp port and decided to try it out with my current TV to see how it works. Imagine my dismay when I found out that no audio is passed through. Video is passed just fine but no sound. Plug the same HDMI cable back into HDMI port and I have sound. Re-plug it back into this adapter off of mini dp port and no sound. TV shows in the list of output sound devices only when connected via HDMI port. I am going to poke around some more but it looks like this adapter simply can't pass audio, at least, on 2012 mac mini. I have a very high quality HDMI cable so it's not the cable, especially since the same cable outputs sound just fine via HDMI port. It has to be the adapter Or Apple lied that an audio pass-through is supported on 2012 mac mini :-). But I doubt it. I don't have any other adapters to try, anyway. Very disappointed indeed.
UPDATE: I've tried it with 2012 Retina MacBook Pro, and with a 4K TV. No audio comes through, only video. So, beware. This item is going back.
