On my surround-sound pc, I use a simple speaker pair plugged in the back for normal sound. When I use headphones plugged into the front, I can hear the sound on the headphones ok, but it does not shut off the external speakers, and sound comes thru both at the same time. The hardware is ok. In windows, the speaker sound automatically turns off when the headphones are plugged in.

Also please advise if I should be using a better driver to utilize the features of my sound system. (I don’t want to invest in a complete 7 speaker system, unless my software will really make use of it.)
Here is a snapshot of my settings in YaST:
