how to get sound on tv through thunderbolt?

hey there odilup, i've had the same issue with my mac pro(mid-2012). The display (my TV) hadn't registered audio output until playing the sound effects like you said. Unlike you, however, the TV won't play audio from videos, etc despite obviously having the function to play audio. Do you have a solution? Tom.

Which adapter do you have? The adapter must support audio!

Have a look in System Preferences -> Sound -> Output if you see your TV.

I had the same issue today, 23 Jan 2013. In case anyone else sees this post like I did looking for an answer and has same issue here is worked for me. Under SYSTEM PREFERENCES> SOUND menu select sound effects. Play a sound effect on your computer. You should see the option to select your TV. Click it. Play a sound effect again and it should now be heard on you TV speakers. Go back to the window of the video you want to play the video... sound should now play through TV speakers. I am using a MacBookAir 2012 Thunderbolt Cable to HDMI. It is amazing! Not sure why it wouldn't play diectly by hiting play or selecting TV audio? I would get an error message say my TV did not support audio out controls.

My thunderbolt adapter supports sound and my HDMI cable is one that I've had plugged into my Apple TV box, so I'm assuming that it works with sound. Yet no sound between computer and regular tv.

I do not have the option in Settings - Sounds to choose anything other than Apple TV or Internal speakers. I've also tried it on a different tv with a different HDMI cable, to the same end. No sound.

My MacBook Pro is 15-inch, 2.53GHz, Mid 2009 with OS 10.9

Help? 😟

Monoprice Mini DisplayPort/Thunderbolt to HDMI Adapter with Audio Support

Alaisa22, greetings: A 2009 MBP will not support sound via the minidispaly port.. For sound, the audio output port will have to be utilized.

Ciao.
