Mute speakers when headset is plugged in

[Luke]

Somehow when I plug in a headset sound is played through it but the speakers don't mute and still play sound still.
I like to have the behavior to mute the speakers if I plug in my headphones or headset.
I guess I  need to enable some switch in alsamixer to make it work.

This is a known problem - I believe that anarsoul was looking into it sometime ago. So for now, you will need to manually mute speakers in alsamixer.
