HDMI output won't transmit sound
 
I have a laptop with an HDMI output port attached, I attached a TV to the port and turned on the laptop. the HDMI display portion works but when I played a video the sounds from the speakers didn't work. The speakers for the TV were on and the volume for the laptop was up. Instead, the sound started emanating from the laptop speakers and not the TV speakers. I was googling for answers but didn't get any. I am running the latest version of Ubuntu Studio on an HP ProBook 4540s

In sound properties, select the HDMI audio as the desired output device. That can usually be found by a click on the sound icon in the toolbar at the top of the screen. In the properties, there is an output tab that lists the available options to choose between and there is also a 'test sound' button you can use to verify that the selection is working.

If you don't have an HDMI audio sound output option, then the system doesn't see it. That is another problem that depends upon the laptop sound hardware and the module that drives it.

The operating system has that icon abs in the corner but whenever I try up open up properties the configuration window never appears. Is there an alternate way I'd getting into that configuration window from like The command line?

Hi

Do you have an ATI Radeon card?

No this is my laptop. I already provided the model in the original post.

Ok, I googled it and found:

It seems to use AMD Radeon 7650M.

You also have to go to the sound setting and select the HDMI sound output.

I'm not sure about the AMD piece. I have the one with the Intel Core i3 processor. But if it does have it like you said then I can probably get PCSX2 working but that's a possible other thread.

To be sure, please provide the output of
Code:

lspci

Just got it working, I ran the command
Code:

pavucontrol
and changed the profile in one of the settings tab to the HDMI output and it started transmitting sounds to the TV, Thats solved.

and here is the lcpi output, I'm sure that it's not running an AMD card. I don't know what kinds of drivers that are needed to run the emulator I am trying to run but that's for another thread.

Indeed, no AMD card, Intel video only.

Shadow_7 03-11-2014 06:23 PM

pavucontrol would be the more common method. Without pulseaudio you would need to change your default sound card.

$ cat /proc/asound/cards

$ echo "defaults.pcm.card 1" >> .asoundrc

Where 1 would be the non-default (0) soundcard on the system. Or re-index the modules for the soundcards so the one that you want to be default is 0. Also note that some hardware on the HDMI recieving end may only take AC3 encoded audio and other quirks. Which may or may not be handled behind the scenes.

baronobeefdip 03-13-2014 12:34 PM

I only wanted it to be changed temporarily. I plan on hooking it up to a TV and playing videos. I wanted to be able to easily change it back so I can use the built-in sound card again.
