you can try this tool: QuickMix
What is QuickMix?
Are you fed up with carefully setting the audio mixer on your Windows computer only to have the settings changed by another application or when you reboot?
Do you need to store and recall different sets of mixer settings quickly and easily? Then QuickMix is for you.
QuickMix is a simple applet that allows you to store all or part of the current state of your audio mixer in a settings file, and to restore the mixer to that state whenever you want.
