How do I get sound out of the HDMI?

Hi Jonas,

Have you gone into Sound Preferences and selected Output > HDMI?

What output device is selected in the Sound pane of System Preferences?

It says that the chosen unit does not have channel out for sound (but in swedish)...

Is that a literal interpretation of the message? I'm wondering what "chosen unit" is referring to.

EDIT: you don't have anything plugged in to the audio/headphone jack at the same time, do you?

Well, I can chose which unit to "recive" the audio signal. If the HDMI cable is not plugged in there is just internal speakers to chose. But when plugged in I can also chose Samsung, type HDMI.

I'm not sure where we are.

First connect the adapter to the MBP and the HDMI cable from the adapter to the TV, then go to System Preferences > Sound >Output > select HDMI.

OK, that appears to be the proper connection and setting. Is it working? What is the other item listed? (Sorry, my Swedish isn't too good.)

So it's saying the chosen unit, the Samsung TV, does not have audio OUT controls. So it thinks you're trying to INPUT sounds FROM the TV. Hmmm.

Are you in the Output tab in this window?

Again, do you have anything plugged into any other audio input/output jack?

Thank you for clarifying that.

Just want to make sure it's not something simple: is the TV turned on?

tjk: I think the quoted message simply indicates that there is no output volume control provided within the computer when the HDMI connection is the selected output device. This standard message appears because the audio signal sent via the HDMI cable is digital, not analog. When the audio output is digital, whether it's via mini-Displayport or a mini-TOSLink connection to the headphone port, the volume is always controlled externally — by the TV set, amplifier, receiver, or powered speaker system to which the signal is sent, not by the computer. A digital audio signal contains no volume information. The device that converts it to an analog signal and relays it to the loudspeaker(s) must provide the volume information.

Thanks eww, I was not aware of that. Makes perfect sense.

Poor, I'm not sure where that leaves us, but if the TV is on and the volume turned on/not muted, and still no audio coming through, I'd try a PRAM Reset and an SMC Reset:

There is often a specific HDMI port on a TV set that is supposed to be used when connecting a computer, though I don't know why. You were probably using the wrong one on your TV, and now you've got the right one. You could confirm this by (gasp!) reading the TV's user manual. ;-)
