That was my solution when my daughter was a baby. Another way is to use your Apple keyboard and hit the Mute key, or put an X in the Mute box in the sound control pane. This works on my G5, 17" Aluminum PowerBook, and 15" Titanium PowerBook, in both OS X 10.3.9 and OS X 10.4.8. Couple caveats: 1) You can't have 3rd party speakers plugged in, and 2) Others have reported that this does not work for them, for some reason. peace, Linda
