I purchased my MacBook Pro around March 2010 and because of this I was worried that it might not output audio over the mini display port (known issue for some models). If this is news to you have a read here. Anyway, turns out mine is fine, so here is how to do it.

First off, if you go to Apple -> About This Mac -> More Info -> System Report -> Audio (Built In) you should be able to see HDMI DisplayPort Output in the list. Check you have this before continuing.

To connect my MacBook Pro to my HD TV I am using a HDMI cable. As my MacBook Pro doesn’t have a HDMI port, I bought a Mini DisplayPort to HDMI adapter. Check out Apple Support as there are only a couple of adapters that will support the audio signal. I bought the Moshi Mini one off Ebay as well as a 3m HDMI cable.

  1. Connect the HDMI cable to the Mini Display Port to HDMI adapter
  2. Connect the Mini DisplayPort to HMDI adapter to your MacBook Pro Mini Display Port
  3. Connect the other end of the HDMI cable to an available HDMI port on your TV
  4. Turn on your TV and navigate to your AV Input selector (press AV button on remote control in my case), then select the HDMI port from step 3
  5. At this stage you should see your MacBook Pro display on the TV but there probably won’t be any audio
  6. On your MacBook Pro, navigate to System Preferences -> Hardware -> Sound
  7. Select the Output tab
  8. Select your HD TV from the device list (in my case Panasonic-TV)
  9. At this stage I still didn’t have any audio but hang in there
  10. Navigate to Applications -> Utilities -> Audio MIDI Setup
  11. Under Audio Devices, select HDMI
  12. Select the drop down arrow next to the configuration wheel at the bottom of this window
  13. Select Use this device for sound output (speaker symbol)
  14. Play some tunes and appreciate richness of sound through your TV speakers
