I've recently been concentrating on some sound-related stuff and got the desktop sounds working for Window Maker.
I've put together packages for both WSoundServer and WSoundPrefs here:

The WSoundServer package includes a default set of sounds, but I'd love to have some more Sound Themes to include if anyone wants to put something together.
You need sox installed and you have to enable sound in the Window Maker Prefs panel to use the sound serve.
