None of these. The driver does not create a symbolic link, because
there's nothing you could do with it, anyway. What do you hope to do
with this handle once you open it?
You open audio devices using audio APIs. If you plan to send kernel
streaming requests directly, then you need to use the system device
enumerator (CLSID_SystemDeviceEnum) to fetch an IBaseFilter instance.
There are different instance file names for the filter and the various
pins, and the APIs know how to manage this.
