Kimberly, can you hear through the audio out port with headphones?

I just want to make sure please, when the hdmi cable is plugged in and running, "line in" is one of the only 2 options under "Output Device:"?

I wasn't sure if you were talking about a display port to hdmi adapter, which isn't a real hdmi cable, or a real hdmi cable.

Newer macbooks have real hdmi ports, and all macbooks with hdmi ports support hdmi audio.  The older ones didn't have them.  They used adapters to the display port, like the vga adapter, in which case the cable may or may not support audio and the port may or may not.  You're not talking about a real hdmi cable are you?

A real hdmi cable will be the same on both ends.  Are we just talking about a display port adapter to hdmi, which is completely different?

If you're using a display port to hdmi adapter, and not a real hdmi cable (since if your notebook doesn't have a real hdmi out), then bobrz's probably right.  Your computer probably just doesn't support audio out through the display port.  If you're using a real hdmi port and real hdmi cable, it's completely irrelevent since they all support audio.

You'll also run into other issues on the tv/receiver end, at least I did, if you're using a display port adapter on a computer that doesn't support audio out through it, because once you use the "hdmi cable" input, your tv or receiver will probably ignore other audio sources for it, expecting it to contain the audio too, at least my old setup did.

That worked PERFECTLY!!!! Thank you:)

EASY GUYS))) system preferences - sound - hdmi - choose input/output.Working perfectly))))))

Thanks for this one. Just used it to get audio from hdmi to tv and works fine. Newbie to macbook pro but LOVING getting used to my mac. Thanks again for the help in these forums.

Ok my friend. this is simple . Go to system preferances > sound > output > Then if you scroll down it sould say TV or samsung or whatever TV you have Click on that then your good as gold !

No didn't work guess it may be hopeless as my Mac is a 2009

Perfect solution. No faf just plain simple instructions that worked. Thanks.

So after my post of 30th Novemeber, I have tried most things on this thread to no avail....

then on Saturday took a trip to my Apple Store with my mac and leads....

It turns out that the HDMI lead I had was perfect, however the adapter lead was not, it needs to be Thurderbolt to HDMI and Apple don't sell them anymore!

I could order more from the internet however like the one I had, it does not necessarily mean that the one they send Is actually Thunderbolt even though they say it is - its just wasting more time!!

Solved it in the end and was all fully working that afternoon, within an hour of my visit and £99 lighter I now have Apple TV and it beats any leads!

Just go for it... worth every penny!!

Good luck all

you are my savior andrewcashew

I bought 29 " AOC monitor with many functions such as speakers, multiplay etc, but with my Mac any of these functions work, not even the speakers. AOC doesn't have drivers for Mac.

I installed the new version of VLC and my speakers are working.

Thank you very much.

So I was having a similar issue with VLC not being able to play any sound through HDMI, yet sound from other apps WOULD play out the HDMI. I saw on here that somebody mentioned to check the audio setting in VLC itself. My HDMI didn't appear there. I recalled that I had VLC open before plugging in the HDMI cable. I completely quit VLC and then re-opened it. voila! It seems as though VLC has to boot up with the HDMI cable plugged in to recognize it.
I hope this helps someone.

I solved this in just a few easy steps under Mavericks.

1. Shutdown computer, UNCHECK to Reopen windows when logging back on.

2. Power computer back on with HDMI plugged in

3. Click on Volume control while holding down Option key and magically my HDMI device appears as a selection.

Hope this helps!

For what year and model of mac book pro do you have?
