My 4670 appears to have only one sound output port, in front of the computer just below the keyboard. From the specs and the computer's own software, there seem to be two sound interfaces. The front female plug works with a 3.5mm headphone plug. I would like to use the digital interface (s/pdif) , but how? 

 

Thanks for reading this.
