I have a 5.1 external speaker system hooked up to my laptop through the aux/ headphones port... and then i have an HDMI cable ran to my 51" samsung DLP... now when i plug the HDMI into my tv it automatically starts producing sound from my laptop which is cool but i'd rather it go through my speakers so i have to set them as my default device... however i would like the audio to come through both... if this is at all possible could somebody please help me out with this???
