Windows will ignore driver name customizations for audio endpoints that have a
“Speakers”-ish KSPIN_DESCRIPTOR.Category.

Subject: [wdmaudiodev] Friendly Names
I'm working on a wave-cyclic virtual audio driver. The client wants the
device and endpoint names customized, of course. Device name is easy,
in the INF file. The microphone name was also easy; create a
MediaCategories entry with the name, and point to the GUID in the Name
field of the KsPinDescriptor in the PCPIN_DESCRIPTOR in the topology device.
However, that same process did not work for the speaker endpoint. It
ends up being called "Speakers". I tried setting both the Name and the
Category in the PCPIN_DESCRIPTOR, I tried setting the Name in the
PCNODE_DESCRIPTOR, I tried setting the FriendlyName in the AddReg
section for the speaker AddInterface sections, but nothing works.
If I change the name by hand, I see the new name in three places:
- DeviceClasses for DEVINTERFACE_AUDIO_RENDER (which is different from
KSCATEGORY_RENDER) in FriendlyName
- Enum\SWD\MMDEVAPI\{0.0.0...} in DeviceDesc
- Enum\SWD\MMDEVAPI\{0.0.0...} in FriendlyName
How can I set this from my INF? Should I add an AddInterface for
DEVINTERFACE_AUDIO_RENDER?
