It's an odd quirk of Snap that they never cleaned up. Some blocks have a "friendly" error message. Delete a variable and uses of it get "Hmmm... a variable of name 'name' does not exist in this context". That one just regurgitates the JS error when it should say "You need to add and select a sound to play a sound".

Nor does it let me select a sound. The drop-down list is empty.

You have to add one, in the sounds tab you can record one, or in the file menu they have a library of them you can load (they also have libraries of sprites and backgrounds which are pretty useful when we use this with students).
