i can't find a button to embed sound clips *.mp3

is it the same as a video file? :D

i found it as a checkbox enabled sound, exploring it now,

hmmmm, doesn't seem to do what i need.

I want the add a line to the event


so that everytime the event collosion occurs it will play this *.mp3 file.

how to do it?

I check here and EJS both cannot find the info easily.
