Mac => Samsung HDMI - No Sound I have connected an HDMI cable between my Samsung Smart TV and MacBook Pro running Sierra.

The option for output displays lists my TV but it says “display port” where I believe it should say HDMIi. I tried a lot of the methods I found online with no success.
I have the same problem and I guess it is due to the adapter. I worked around it by adding an extra cable from mini jack to stereo cinch just for outputting the audio. The mini jack audio output is located on the other end of you MacBook.
