Use both Speaker types, Bluetooth and Realtek

I just bought a bluetooth speaker (Logitek). It coects to my desktop computer fine, and I can easily switch between my computer speakers and my Realtek ones using sound-playback devices-enable/disable.

However, I caot figure out how to get my bluetooth speakers and computer speakers to play at the same time. Is this possible to do?

My operating system is windows 7 64 bit.

Thanks
