Hi,

according to Matthews outline of the Windows default audio device evaluation 
process at
https://matthewvaneerde.wordpress.com/2014/03/24/troubleshooting-default-audio-device-heuristics/

its possible to kind of "downvote" a device by setting 
PKEY_AudioEndpoint_FormFactor of the endpoint to something “unattractive” for a 
default device to Windows.

This works, however all other endpoints of the same and all endpoints of 
another device instances disappear by doing so.
I guess there is some misunderstanding on my side here.

Any hint or advice of how to make a device unattractive enough to Windows to 
not being automatically selected, while still allowing the user to make it the 
default on its on wish are highly appreciated!

Thanks & viele Grüße/Cheers,
Hagen.
