The default audio output is “Internal Speakers”, so it’s no surprise that while we’re seeing the video on the TV, the audio is still being piped out of my MacBook Pro speakers. To switch it, choose System Preferences off the Apple menu, then look for “Sound”: It all looks good, but the audio is coming out of my computer even as the video is being fed to the HDTV. I’ll start with a frame from a movie trailer (can you identify it for two points?)

Let’s start there and then if it’s still not working, I’ll show you what to look for in your hardware configuration app to check your HDMI / Display Port capabilities. Switch that and *poof* you’re good to go!

It’s about mid-2008 that the Apple hardware started to support HDMI audio, based on the research I’ve done, and there’s a pretty easy way to find out if your particular device works or not.īefore we do that, however, odds are that the problem is much simpler: your Mac probably just isn’t configured to use the HDMI adapter as the audio output for your system when you have things plugged in. How old is your MacBook? If you have one that’s too old, it turns out that it might not be able to push audio through your DisplayPort, in which case the HDMI adapter isn’t going to be able to perform miracles, sorry to say.
