    When there's no Linux Nvidia HDMI audio output Nvidia

    Apart from no audio over hdmi to the tv - Ubuntu 10.10 maverick worked beautifully
    This fix worked for me

    Gigabyte GA 73PVM-S2H
    Nvidia GeForce 7100 / nForce 630i
    Linux-x86_64 Ubuntu 10.10 maverick 64-bit
    Kernel Linux 2.6.35-22-generic

    Nvidia Driver version 260.19.06 (current recommended additional driver)
    X Server version 11.0
    vendor version 1.9.0
    NV control version 1.24


    Alsa version 1.0.23

    --------------------------------------------------

    Terminal commands to run:

    [First]
    sudo killall pulseaudio

    [Second]
    alsamixer

    Make sure that the HDA NVidia card has been selected,
    if not, press F6 and select
    0 HDA NVidia

    Make sure the S/PDIF's are unmuted.

    Scroll right and unmute S/PDIF, S/PDIF D, S/PDIF 1

    Press m to unmute and MM should change to OO

    ESC to exit alsamixer

    ---------------------------------------------------

    Next we edit the following file as su:

    /etc/pulse/default.pa

    use nano or vi or any other editor

    eg. sudo vi /etc/pulse/default.pa
    or
    eg. sudo nano /etc/pulse/default.pa


    Goto lines 44 & 45 and unmark and edit as follows

    load-module module-alsa-sink
    load-module module-alsa-source device=hw:0,3

    exit and save changes

    Choose the relevant HDMI output you need in Sound Preferences (System->preferences->sound)

    i didn't reboot and it started working.


    [If this works for you too, please leave a comment so others know it worked...thanks]

    UPDATE:

    Had some problems with my wubi installation, once that was back up and running - no sound!
    Waiting for sound system to respond

    opened default.pa and #'d the two lines edited before and the sound returned....

    go figure
