if you set a command "play mediafile x after connect" it sometimes nervs to hear the sound constantly.
with a checkbox in the sound tab u could give the user the possibility to choose if after command: x flashfxp should play the file while u are using the pc.
maybe it could be realized with mouse-moves
if the user doesnt use the mouse mybe for 30 sec then flashfxp hast to run the command listed in the soundstab for the current action.
