OK. With that fixed, I get both sounds without "/W10" and no sounds with "/W10".
Two problems - you're using FOLDERMONITOR & /W incorrectly, and you don't understand how it works.
First, you would never use /Wn with something like a create / delete / rename, only with something like a write & modify. Which takes us to problem #2 - the way it works is that TCC calls the Windows API and waits for a change to the file / directory. When one happens, Windows returns the info and TCC starts its timer and calls the Windows API again. When another action occurs, TCC checks the timer to see if the wait period has been exceeded and if so, TCC executes the action specified in the FOLDERMONITOR call.
So if you only have the monitored event occur once, you won't see the action executed.
(Also, the /Wn needs to be the first argument to FOLDERMONITOR.)
