I was just thinking that it might be pretty useful to have a condition for "Is sound with tag ("music") playing" or something similar, where the user could enter in a sound's tag as the sound to check for. If no sounds are playing with the defined tag, obviously it returns false. Inversion would be an obvious must as well.
I just came around to thinking about it when I was trying to figure out how to control music across multiple layouts. There are other ways to pull it off (global variables come to mind) but this would make it an easy one-event solution.
Any other suggestions for the Audio Object are certainly welcome in this thread.
Also, on an unrelated note, any word on the "move in front of object"/"move behind object" z-ordering actions? <img src="smileys/smiley2.gif" border="0" align="middle" />
