Not quite true. If two same-named audio controllers are in the same system, the
names of the controllers (as seen in the Sound control panel) are modified to
differentiate them. This also affects the friendly name that is retrieved via
the PKEY_Device_FriendlyName property of the endpoint property store.

Thanks for the hint. Our driver is a replacement for class-compliant
driver, that's why it does always extract device name from the
firmware, which is supposed to contain localized unicode name.
However, I wonder if that's the only possible way. Anyone from
Microsoft can confirm this please?..
Also, Windows XP used to add " (n)" at the end of the device name if
multiple instances are created. Vista no longer modifies the name,
thus, if two devices are connected, they both will receive exactly the
same name, this is not user-friendly.
