Mit der Tastatur? 😀

Na, halt aussen drumherum packen:

on mouseUp
   if the environment = "mobile" then
      if (mobileSoundOnChannel("background") is empty) or (mobileSoundOnChannel("background") is "could not find channel") then
         put (specialFolderPath("resources") & "/sound/background.wav") into tPath
         put "background" into tChannelName
         put "looping" into tType
         mobilePlaySoundOnChannel tPath, tChannelName, tType
      else
         mobileStopPlayingOnChannel "background"
      end if
   end if
end mouseUp

Hinweis:
Falls Du hier und in ähnlichen Fällen keinen ELSE Fall benötigst, schreibe ich das immer so, einfach der Übersichtlichkeit halber und um unübersichtliche IF…THEN Klauseln zu vermieden:

on mouseUp
   if the environment <> "mobile" then
     ## Dann einfach nicht weitermachen! :-)
      exit mouseup
   end if
   
   if (mobileSoundOnChannel("background") is empty) or (mobileSoundOnChannel("background") is "could not find channel") then
      put (specialFolderPath("resources") & "/sound/background.wav") into tPath
      put "background" into tChannelName
      put "looping" into tType
      mobilePlaySoundOnChannel tPath, tChannelName, tType
   else
      mobileStopPlayingOnChannel "background"
   end if
end mouseUp
