I am trying to set up some 5.1 surround sound speakers with my VAIO vgn-A115M. I can only get 4 of them working because there are only 2 output ports and i need 3. My friend has been able to get round this problem on his computer by configuring his audio jacks to make the microphone port into an output port. Is it possible to do this on my VAIO or is there any thing i could buy (e.g. software/new sound card etc.) which would make it possible? Any help on this would be much appreciated as i really want to get my speakers working to their full potential.
Cheers
