    Audio mute fix
    Works everytime for me,
    This issue may be a problem in pulseaudio. I managed to get it to 
work as expected by replacing the line

    load-module module-device-restore

    in /etc/pulse/default.pa with

    #load-module module-device-restore


    Now set audio where you like and log-out on log-on to make
    sure of fix.
