Q: No sound through hdmi - macbook pro

thanks

I have tried every option suggested in this thread, but I never have an option to select TV or HDMI. What am I missing? I have a macbook pro purshcased new in Nov. 2012 from Apple. I connected to tv using a Mini display port to HDMI cable. Video works fine, but no audio.

now i keep getting this and i figured it out, so easy, but have since forgot.....there is a setting like midi, but different and can't remember it......i have been looking for the post where i saw this since last nite.....arghhhh

k

i guess it is just the midi settings that i am talking about....but the settings r all set to hdmi output.....frustrating

bister07, just make sure u r hooked into your tv and on the correct channel , otherwise the hdmi option will not show up

Hey, I tried setting up the audio and it didn't work until I did some fiddlin around. So when you plug in the hdmi to your tv, in System Preferences>Displays, you should find you tv in that category. Now, open Utilities>Audio HDMI Setup. Bottom right hand corner, click the + button and select Create New Multi-Output Device. Now a new catagory called Multi-Output Device should appear. Click it, select HDMI and check off the box and there you go.

Hey, check out my previous reply to ashhhbee. This should work. Remember though, when the mac is connected to the tv, it should display the mac desktop, and not be functioning as a second display.

Thank you so much!

Holding option while clicking on the speaker icon worked for me too, to let me swich audio sources.  It's weird the default is not to play sound through the HDMI or give you visible options when you are connected to HDMI.

Thank you again.

Go to System Preferences --> Sound --> Output --> Click On The Tv Output. For me I plugged my hdmi from my Macbook Pro to my Samsung Tv. As soon as I clicked on the tv it did not appear as nothing happened. But no sound will come from your laptop but will transfer sound to the tv. Test the sound by playing music to make sure it works.

I too have tried EVERY reset, settings options etc and no joy....My son was having the same issues using my HDMI cable when he was visiting and he tried the PRAM reset and it worked but my MacBook sadly a PRAM reset did nothing :( I can not get the TV or the HDMI to show up anywhere ...Help

Is it displaying the video at least, confirming that the connection is getting through?

If you have video at least, what do you see when you hold down the option (alt) key and click on the speaker icon on the top right bar (by the airplay, bluetooth, etc. icons).

I didn't know this either till I read it here, but when you hold down the option button and click on the speaker icon, instead of volume up/down, you get the input/output selection options.

The MBP has to be at least a 2010. Prior to that HDMI didn't carry sound. You'd need another cable from the headphone jack on your Mac to Audio In on the TV.

Did they say it was an older macbook?  At the very least they should try what i said before assuming it won't work...

Any Macbook with a real HDMI output should play audio just fine through the HDMI the way I said unless it's broken.

I think maybe you are confused and talking about the old miniport to hdmi "adapters", in which case you would be right.  Usually anything that is "whatever to hdmi adapter" doesn't carry sound.  It seemed like they were using a real hdmi cable.

Sorry for sounding snarky just want to give them a chance to try it before throwing the tip out the window knee-jerk, or confusing unnecessarily.

If it's a real HDMI port and cable, it should carry audio fine and you can hold down the option key to select input/output options.

If it's some sort of display port to hdmi adapter, and doesn't have a real HDMI port like with older macbooks, you're totally right.  They'll have to use the audio out.

Yes the video works fine just no sound. I checked and when I "hold down the option (alt) key and click on the speaker icon on the top right bar" my options are "line in and internal speakers" when line in is selected the sound only comes from my laptop not the TV.

Yes that is what I thought too when I use a a VGA cable this is what I did. The same set up does not work with the HDMI cable I have tried using the seperate "headphone jack on your Mac to Audio In on the TV" and still no sound.

OK so no seriously my son plugs in his Macbook pro and it works fine and then two seconds later I plug in mine and no sound video works fine. Smae cable, same adaptor etc. His computer is newer, but he had to reset the PRAM to get sound to work properly. I followed the same procedure...reset PRAM and no dice...or sound
