How to change the default audio device?

Question

Automation

I have speakers connected to the rear audio output, and headphones are output to the front panel. When I plug in my headphones, the sound goes through them. When they are not connected - to the speakers. But I'm tired of poking the connector back and forth. Is there any software tool to switch the audio device on one click, or on a hotkey? Switching by script/command line is fine.
OS - Windows 7 x64

PS "Click - Playback Devices - Click - Use Default - OK" - do not offer.
