Internal and External speakers at same time but for different software

Hi,

I have a secondary monitor and it is working properly. The objective is to play video and sound for external monitor with external speakers (daughter listening to videos) and my game on my laptop screen with internal speakers.

I have a XPS Laptop with Win 7. I currently am plalying two software at same time, but both play sound in the internal speakers at same time (or external if I plug the jack) without sound issue. Is it possible to have first software playing sound in the internal speakers and second software playing sound in the external speakers at the same time?

Thanks
