4. How to identify the various SendStation Mini DisplayPort revisions?

Rev. A adapters (made until mid-May 2010) have a dull, light-grey enclosure. The HDMI version has no support for digital audio via HDMI.

Rev. B adapters (available since mid-May 2010) have a glossy, white enclosure. The HDMI version does support digital audio via HDMI.

1. Does the SendStation Mini DisplayPort Adapter provide sound via HDMI?

Yes. The SendStation Mini DisplayPort HDMI adapter (Rev. B as available since mid-May 2010) supports audio via HDMI. Note that older Macs do not provide the audio signal on their Mini DisplayPort.

If you’ve purchased a SendStation Mini DisplayPort HDMI adapter (Rev. A as before May 2010) or your Mac doesn’t provide audio via MDP, the solution is to use the audio out jack on your Mac and connect it using a separate audio cable with your TV or stereo.

See above on how to distinguish between Rev. A and Rev. B.

2. I can see the HDMI video on my TV set, but I can’t hear any sound.

First of all make sure that your SendStation Mini DisplayPort Adapter is Rev. B, as Rev. A does not support digital audio via HDMI (see above on how to identify the revision).

On your Mac you may need to adjust the audio output from the internal speakers (or headphone out) to HDMI output. To do so, go to Apple Menu > System Preferences > Sound and click the Output tab. Note that the HDMI option will only show up when using a Rev. B adapter and if the HDMI (audio) connection between the TV set (or Surround Receiver) and the Mini DisplayPort Adapter has been established. In other words: The HDMI audio output will not appear if the cable isn't connected on the HDMI side to the TV or the Receiver.

Note that on many TV sets and/or Surround Receivers with HDMI loop-through you have the option to combine the HDMI video signal from one input with an audio signal from another input, even an analogue one. If you can see the video from the SendStation Mini DisplayPort Adapter but can’t hear the sound, there’s a chance that according to the settings of TV and/or Receiver video and audio are chosen from different sources. Make sure that on both the TV and the Surround Receiver video and audio signal are set to come from the same HDMI input.
