[How To] Fix No Sound Through HDMI In External Monitor In Ubuntu

Care to Share?

Problem Scenario:

No Sound Ubuntu HDMII connected my laptop running Ubuntu 12.04 to my Samsung TV through a HDMI cable. I used extended monitor and everything (in terms of display) looked fine. The problem occurred with sound. I expected the sound to play through the TV (or say monitor), but it was still coming through the laptop’s inbuilt speakers.

Reason:

I saw a number of forum posts with trouble on the audio problem in extended monitor in Ubuntu. Thankfully this problem was not complex, at least in this case. The reason in my case was that the default sound setting was “built-in speaker audio”. Changing it to HDMI saved my day.

Solution:

Open the sound setting. Type “sound” in Unity dash (by pressing the Super/Windows key) or from the top right corner choose the system settings and then look for sound setting.

Ubuntu System Settings

In the sound settings, in Output tab the built-in-audio was set to Analog Stereo Duplex. Change the mode to HDMI output Stereo. Note that you must be connected to an external monitor through a HDMI cable to see HDMI output option. When you change it to HDMI, a new icon for HDMI pops up in the left sidebar. Click on it and enjoy the sound of music.

Feel free to ask questions in the comment section. I’ll try to help. Cheers :)

      I am not sure if get you completely. Did you mean that you can hear the music player on TV but not youtube video playing on Chrome?

    I have the problem that there is no option in sound, output for hdmi. The TV is connected and displaying alright but just no option to select hdmi.

      Do you have Pulse audio installed?

      • Greg Goodsir

        Yes.

          Hi Greg,
          When you have your TV connected, could you please send me screenshots of the Audio settings? You can attach the pictures in the comment section.

            Was there a resolution to this problem? I am having the exact same issue.

      • Greg Goodsir

        So will I need to uninstall pulse and install aslsa?

    Here are my Settings in Ubuntu 12.04, Catalyst 12.10 and internal LG TV sound setting.

    I cannot upload screenshot 3. It opens alright in “Image Viewer”. It is just showing the second tab of multi display with a diagram of their relative size.

      I see that Mode has been set to “Analog Stereo Output” Can you try changing it to HDMI?

      • Greg Goodsir

        In the Mode there is no HDMI option.

    How would this be done via the terminal? I don’t use unity; too resource intensive.

    That’s fantastic, but what happens when the hdmi/display port option doesn’t even show up or exist? I even have indicator sound switcher 1.2.2 and it switches to hdmi. The basic settings won’t even acknowledge it. . .

      Reinstalling pulse audio may help.

    I’d thought of installing proprietary soundcard drivers and everything but forgot to just check the sound settings! Thanks man! =]
