uman,

That worked perfectly. I even left the Azalia audio in there.

The system profiler does not show anything. The sound effects cannot be enabled (I just have a greyed out pull down list), but they seem to work. I just checked if I could hear the trash being emptied. It does.

Devices are listed in the sound preferences.

That was a gem. Listening to WGBH over iTunes as I write this
