I suspect you won't, at least not directly. If the search is narrowed to 
specific versions of windoze and dshow, it may get easier.  (On a modern 
win10 thinkpad here w/ OBS, the only audio output captures are the named 
sound devices - "Speakers (USB PnP Audio device)" and "Speakers (Realtek(R) 

IME most windows capture software uses pick lists to get the desired device. 
You might be able to script something to simply use the first device, but of 
course, that might fail on some.
