Right when my Ubuntu shutdown there is a loud cracking noise. I know what the problem is. It has to do with the audio. The audio is not unloaded, so it sounds as if I held the power button. This does not happen in vista. I can see that the audio is mute before vista shutdown, because it glows read on my touch pad. How can I mute the audio before shutdown, for a quieter shutdown.
Thanks for all your help
