    HDMI Input on Alienware M18x

    I have an Alienware M18x laptop that has an HDMI input. I dual boot between Win7 64-bit and Ubuntu 11.10 64-bit. When I am in Win7, the HDMI input works fine for both audio and video when I plug my PS3 in to play it on the laptop's monitor; however, when I am in Ubuntu, only the PS3 video comes through without any audio.

    I can't seem to find any answers searching throughout the Internet. Can anyone help me figure out why the audio won't come through when I use Ubuntu?

    Thanks!

    Hi stanjr. HDMI input on a laptop? That's really cool!

    This is what I do: First I would check if the device is being recognized as an input device:
    Code:
    arecord -L
    Then, I would check if the input is muted using alsamixer:
    Code:
    alsamixer
    Remember to press F4 to see the input (capture devices).

    After that I would select the input device on 'Sound Properties' before connecting your PS3 (like you would do if you had several mics and wanted to record from one of them).

    Hope it helps, and let us know hot it goes.
    Regard.

    The only type of audio inputs I have listed under Sound Settings are:

    Internal Microphone
    Analog Line In

    It doesn't seem that an HDMI inupt is noticed at all there.

    Yes. It looks like the device is not visible.

    Could you post the result of these commands?
    Code:
    lspci | grep -i vga
    
    sudo lshw -C display
    Regards.

    Hello,

    I have been trying versions of ubuntu including 11.10 64 and 32-bit on my M18x. It hangs every time. I have also tried wubi as well as dual-boot. You seem to have gotten ubuntu to work? What might I be doing wrong?

    I originally had the fresh install of Win7 64-bit installed on it (as it came), then installed a fresh install of Ubuntu 11.10 64-bit for a dual-boot situation with grub2. Everything seems to work fine (except, of course, the hdmi input audio). I don't know what might be going wrong
