    Hello All
    I just noticed a issue with my mac pro
    Sound is always coming back from internal speaker after restart
    Wen I go to system preferences and switch it to line out it starts working again
    Until I restart the computer and I have to redo it again
    Any ideas would be greatly appreciated

    try deleting the two plist files in /Library/Preferences/Audio and then rebooting.
