Welcome to the forums and thank you for the kind words regarding the site.
Your question makes perfect sense, but unfortunately I think that what you want to do would involve defining a seperate and distinct hardware profile, where you could select a particular profile at boot to use with different hardware options pre-defined, a feature that Microsoft has dropped since XP (it wasn't actually available in Vista and is not available with Win7).
As you probably already know the options are easily changed/adjusted by right clicking the speaker icon in the Notification Area (formerly system tray) and selecting "Playback devices" and choosing one of your device there.
Hope this answers your question.
Kind Regards
Randy
