You don’t need separate endpoints for this either. Each application has its own
volume control, independent of the endpoint volume control. Also, different
audio streams within the same application also have their own volume control,
independent of the application volume control.

endpoint
The idea is to use separate volume control for skype (communication
device) and e.g. PC game (render device) volume, it is called "chat
balance" in gaming. Or probably use separate APO for different
processing for these devices.

I'm quite new to wdm/ks Windows stuff, but keen on learning all this
recently. The idea I'm trying to elaborate is possibility to have 2
separate audio devices in Windows 10 from one physical rendering
device: one default device and one default communication device, so
different applications could use them separately.
Windows already allows several applications to use one device simultaneously,
and of course a single device can be both default device and default
communications device.. Why do you need separate devices?
The question is - how to output data from MSVAD driver (from CopyTo
routine) to existing endpoint (USB headphones)?
As you say, by using a user mode helper. Ugly, and I suspect unnecessary in
your case.
