Speaker endpoints are hardcoded to be "Speakers" because there were so many
devices with speaker bridge pin friendly names like "volume control" or "master
volume" etc. which made no sense at all as a device name. It was something
that we didn't want to do but it fixed a common problem across a lot of legacy
devices.
You are correct that we had to make some suboptimal design choices to
accommodate the simple devices which comprise the vast majority of hardware.

Mitch

Hello Hakon!
> That node type name is hard coded in Vista By Design.
But why? If there is a category field and an OPTIONAL name field, what
is a logic for that? For applications, it is much more better to look
for an appropriate endpoint by a category, not by a name. For a
driver, it may be better to specify a compatible pin category but a
different name to distinguish between similar subdevices.
I see that some changes from XP to Vista are made as there were only
dumb, simplest audio devices having only microphone/line inputs and
a speaker output :(

Eugene
