Well, does sound work in Etoys otherwise? Like, in the car's viewer, if you click the yellow exclamation mark button next to "car make sound", do you hear anything?

Also, the position slider should start moving.

Well, you have the full Squeak development environment at your disposal, if you care to learn how to use it ;)

You can press the view-source key on the XO, or Control-Comma. That gives you access to the dev tools. Execute any code you see or type anywhere by pressing Control-D (or Control-P or Control-I, just try the difference on "3+4", for example).

Also, you should enable the "debugHaloHandle" preference. Then right-clicking will give you a wrench icon in the halo, that lets you explore the object on screen. (I usually keep this enabled using the "set automatically on startup..." preference menu item)

If you have an object selected in the object explorer, press ctrl-b to open a source code browser. Or click the middle mouse button to bring up a menu (control-click works if you only have two buttons).

That's pretty much all you need to figure out what's going on :)
