Nope, does not work.

Theres a much much easier way!!!! Just get a external speaker with an mp3 cord and plug the mp3 into the macbook! then sound will play via external speaker.

uncheck mirror option under display setting, you should be able to get sound to your tv now.

just go to sound in application --> output and click on HDMI.

I just bought a new adaptor and have it connected to my TV. Video works fine. I've read through all the threads and I am not getting a single option for HDMI audio. I have a MacBook Pro Mid 2012, I have checked under audio MIDI and the options are not even located there for HDMI audio. The adaptor supports audio too. The HDMI cable I have supports audio. Under preferences, there's no option for HDMI "output", I'm only given internal speakers output and my Apple TV output. I've tried restarting my system, shut it it down and restarted, logged-off and restarted. NOTHING. !!!!!!! Oh, and I'm running Mavricks with the most recent update.

I have a Belkin Mini Display Port to HDMI Adapter that i pug in to my Mac and then plug an HDMI cord the is connected to a Pyle PT590AU, the Pyle is connected to speakers. The only problem is that my Mac won't output sound to them. So now i just have all of this expensive equipment sitting here and I'm still just using the mac speakers. I've tried all the solutions to get sound to output to a TV, and they don't work for this. Please help me!!! - Thanks

Hi All,

I'm having with the same problem with my Mac pro 2008 too!! The picture is coming in clear but there is no audio at all coming thru my Vizio Smart Tv! I would to hear from anyone with good advice!! I have tried everything!!  HELP!!!

I used exactly the same steps and finally got sound from my MacBook Air 2013 with OS 10.9 and LG LCD TV (2008).

Thanks a lot.

i just bought a Belkin Mini port and was having the same issue. But found the problem. Just need to go to the Audio settings of the media player and select the output you want to use, select HDMI and it works. We are currently watching and listening directly on my our tv. I had to reser my TV at some point as it was also causing an issue but that was just a matter of unplug all cables including the power cable and reconnect everything. I tested this with a Sony and Samsung TVs. Hope it works for you too!

Not sure if this is the right place to leave this but I had a similar problem on my Mid-2010 MBP. Sound suddenly stopped playing on my TV. I took some advice from a previous comment and went into Utilities>Audio MIDI Setup and basically did nothing. What I mean is I changed a couple things, changed them right back, and that worked. Sound began playing through my TV again. I can't explain it, but it worked.

I bought a non-Apple cable and never would have figured this out - thanks for posting it!

It's been 4 years since your post - can't imaging why Apple doesn't fix this (make it default these values).

If anyone is still looking at this thread, I could use some help.  Per the theme: trying to hook MacBook Air to TV.  Get picture, sound still plays on the MacBook, not the TV.

I have a mid-2013 MacBook Air, OS X Yosemite.  TV is a Sony Bravia R55.  From my MBAir, I am connection a Belkin MinDisplayPort to HDMI adapter, connected to an Amazon HDMI cable, to the TV.

Tried the Systems Preferences>>Sounds>>Output>>select a device option.  However, I can only see "internal speakers", no matter what I do.

Tried the Finder>>Applications>>Utilities>>Audio MIDI Setup, but again, the only option is "built-in output".  Nothing about selecting HDMI or the TV or anything.  Someone on here had recommended "Create Mutli-Output Device" from the Audio MIDI Setup window, but that didn't work, either.

Even tried fooling around with the default 44100.0 Hz options, but still nothing.

Any solutions???

VERY late for the train here but I think I see one solution.

Connect your TV via the HDMI adapter and cable.

Open Utilities > Audio MIDI Setup.

Click on OUTPUT. You should see HDMI as one option. Click to highlight this.

Find the GEAR at the bottom of the left-hand sidebar. Click this and select Use This Device For Sound Output.

You should be home free.

TV is NOT displayed as an option for sound output.

Unplug the TV (not just turn off), and unplug the HDMI cable from the TV. 

Not sure if unplugging both is necessary, but it works for me when this happens.

Also, I don't think you have shut down the mac. Last time this happened it wasn't necessary.
