    12.04 HDMI Problem

    Currently running 12.04 (aware its beta)

    HDMI output for video is perfect
    Sound doesn't recognize every time,
    Looking for a command to search for audio outputs or possible solutions.

    Hope theres a solution and if not this helps to find one.

    Did you tinker with the sound settings at all? I noticed if I do HDMI I have to change which "audio card" it comes out of, as I'll see HDMI Output + my sound card as an option. Once I select HDMI Output it comes up fine.

    I believe it's under Sound Pereferences... then through one of the tabs. Play a song or something and click through each option. I kind of forget which one mine is offhand, but that's where I fixed mine, at least.

    Yes i am with that part my problem is its not showing up in the sound settings every time. Its inconsistence. Like if i reboot with it plugged in it will work fine, But i am on the go a lot and i would enjoy it to auto recognize when i plug it in. Video has no problems every time i plug in just the sound is inconsistence

    Thanks

    You might try
    Code:
    killall pulseaudio
    in a terminal. pulseaudio will restart on its own. That has been known to fix some sound issues.

    Good call, pbrane! I wasn't aware of that fix.

    Nessto - It would help if you could tag the thread as solved.

    Does not make HDMI audio available for me.

    HDMI Audio works on boot but for some reason it disappears sometimes and I have to log out > login to get it back

    It may have something to do with screen power management(System Settings> Brightness & Lock).
    When HDMI Audio dies I checked System Settings>Sound and HDMI Audio is no longer listed.

    I have this exact same problem. If I reboot the HDMI card is available but after sometime it becomes unavailable and I have to reboot (logging out and back in doesn't work for me)

    @SushiAddiction, did you find a solution?

    a quick way to solve it is to run a program that uses sdl sound and then close it and sound will be restored. however this is just a temporary fix
