Hi, Matt,
Isn't the friendly name this: g_PINNAME_AUDIO_RENDER or
g_PINNAME_AUDIO_CAPTURE?
It is commented out in the example I sent you...but, that is what I had
orinally...at some point in my testing I decided to go with those other
names...probably because they were in some other PortCls driver I had
written.
But, I will try those again, right now...just to make sure...
Or, if those are not the "friendly names"...then maybe I don't know what a
"friendly name" is.

The first thing I notice is that you don't have any friendly names for
your pins - the Name member of KSPIN_DESCRIPTOR. This may actually be
all it takes. Try adding that - if that doesn't work, I'll do a closer
look.
Windows Vista will use the friendly names of the pins to name the wave
devices, so you'll want to do this anyhow.
