    Periodic no sound from HDMI


    Occassionally, I will get no sound specifically from web pages with what I assume
    is an embedded sound file, but mostly from YouTube flash files. Even rebooting
    or complete shutdown will not correct the situation. It seems to resolve itself
    after a while.

    Windows sounds continue to work properly as well as movie files I play through
    MPlayer or sometimes Media Player.

    I cannot track down what is causing the intermittent sound loss. Right-clicking
    the sound icon in the task bar and selecting playback devices always reveals the
    same setup:

    Realtek HDMI Output
    ATI HDMI Audio
    Default Device

    Nothing is changed since the original setup and troubleshooting only points out
    that Speakers or headphones cannot be found which would be expected with an
    HDMI setup.

    This is really bugging me and I'm wondering if anyone else has experienced this or
    similar problems.

    When using the HDMI audio, the video card is using it's own built in sound device, not the PC's sound device. If the sound works OK with the regular PC sound (Realtek) and PC speakers, the problem is in the Video Card's sound system.

    Youtube uses Flash and that has known to be iffy at times. Make sure you have the latest version of Adobe Flash. Some web pages with embedded audio use Windows media player extension and with the HDMI audio that may also be a problem.
