    So what..
    Do you have a problem with no audio over HDMI ?

    I suspect that full HDMI audio capabilities is only possible when using nVidia driver but not sure with chipset HDMI audio..

    dmesg | HDA
    ls -al /proc/asound/card0/eld#*

    if eld#0.0 etc files exist then post contents
    i.e.
    cat /proc/asound/card0/eld#1.0

    yes the issue is in fact that I have 0 audio what so ever over hdmi My only means to transmit audio is over the hdmi cable Ive never looked into this before as I always had a standalone home theather system that I ran headphone to rca cable converter and played soudn through there well now I no longer have that option so I must transmit the audio over hdmi

    do you want me to run those commands btw?

    You don't need the latest nVidia driver..
    Installing from nVidia directly is a bad idea, recipe for problems later..
    Much better to use launchpad ppa & use package management.

    HDMI audio:
    What you have to have is alsa-1.0.24 (or later) userspace (libraries utils) v& proprietary video driver.

    With lucid 10.04 you need to add the iQuik audio ppa to upgrade alsa user-space to 1.0.24.

    Ok quick update, Fresh installed Headless

    #apt-get update

    #add-apt-repository ppa:team-iquik/alsa
    #add-apt-repository ppa:ubuntu-x-swat/x-updates
    #apt-get update
    #apt-get install xubuntu-desktop nvidia-current
    #apt-get dist-upgrade

    Dist-upgrade upgraded alsa to 1.0.24, thats where im at atm let me know where to continue and since I fresh installed pulse audio is back on it again

    pulse-audio is not a problem..
    You didn't need to make a fresh install just to remove the nVidia driver..

    aplay -l
    dmesg | grep HDA
    speaker-test (reports the alsa user version)

    The eld# stuff posted earlier is likely pointless as I think your chipset HDA audio does not support ELD reporting.
