Macbook pro audio out + built in speaker

This may be a stupid question, but does anyone know if it is possible to output audio from both the 3.5 audio out as well as the inbuilt speakers on a MBP model MB133*/A?

Typically for a laptop soundcard that has both internal speakers and a headphone out, there is only one amplifier, and the output can either go to the speakers or headphones, not both. Often the switching is analog - plugging in the headphone jack physically breaks the circuit going to the speaker while connecting the signal to the jack.
