What you'd want to do, is have a timer that toggles the sound on and off at 5 sec intervals. To do this, call the sndPlaySound function with the loop flag to turn it on, then call it again with "" for the filename to turn it off.
For example, in the code that plays the sound, say TimerOn_Timer(),
lResult = sndPlaySound("c:\my documents\wailingalarm.wav", SND_ASYNC or SND_LOOP)
TimerOff.enabled = True
and then, after 5 seconds, in the TimerOff_Timer() event,
lResult = sndPlaySound("", SND_ASYNC)
TimerOn.enabled = true
P.S., It'd probably be better to just use on timer and toggle a value to determine whether to play or stop ... I used to just to make it easier.
