I'm not experienced with Girder and sadly have no time to get to grips with the features, however I can pay $20 via PayPal to the first person to reply here with a link to a GML file (or precise step-by-step instructions on how to create one) that does the following:

When MCE is detected as running, peform the following:
Restore the window so it is windowed not maximised
Switch audio output to Sound Card 1
(I can tweak this bit when I receive the file, or alternatively I already have a .reg file that does this which Girder would need to run, then press enter twice with small delay to accept it into the registry)

When MCE closes and is no longer running, perform the following:
Switch audio output to Sound Card 2 (notes as above)

Good luck and may the force be with you. :lol:

Thanks!
