2. If the application quit, then the sound is killed.

I had to use a global to do this. (I don't usually use globals.)

I had to learn behavior of idle and quit handlers that I didn't know.

Here's the final script ...

on run

global soundpid

choose file with prompt "Choose an audio file ..." of type "public.audio"

-- Cancel Quits here

set fileAlias to the result

(quoted form of (POSIX path of fileAlias))

set soundpid to do shell script "afplay " & the result & " &> /dev/null & echo $!"

end run

on idle

global soundpid

try

do shell script "ps -p " & soundpid

on error

quit

end try

return 1

end idle

on quit

global soundpid

try

do shell script "ps -p " & soundpid

do shell script "kill " & soundpid

end try

continue quit

end quit
