I have a sound card which i plug my speakers in to at the back of the pc and this works fine.
Now I am trying to get on Teamspeak and have a headset that has 2 jacks pink and green which matches two ports on the front of the pc.
I expected to just plug and play with that but when I plug them in the front, the sound continues in main speakers, nothing herad in headset.

I expected the headset to overide the speakers and all sound would now go through the headset. I have no idea if the microphone would work at this point.

So
1) How can I enable the front ports to work, ie send out and receive sound.
2) can i get the headset to overide the speakers when I plug it in, or do I have to unplug speakers each time I want to use?

Thanks in advance.
