BleepingComputer.com: Sound Driver Auto Switch

Hi, I use several different audio drivers on my laptop. At home, I use a usb sound card for my speakers, on the road, I use the laptop's internal sound card which has a seperate driver. When watching movies, I select yet another driver to output the sound over hdmi. And then, finally there's the driver for my bluetooth headset. Is there a way to switch drivers automatically or more easily instead of doing it by hand everytime?

maybe someone can point me in the direction of how to accomplish this. thanks.

additionally I'm searching for some software that automatically starts applications on system startup based on network location. I think this can also be used to automatically set the audio driver.
