Which name are you referring to? In my case, the name seen in the Volume
Mixer, or the list of audio devices is "Speakers (Friendly_name_in_here)". I'm
guessing this can be overridden by entering a custom GUID in the Name field in
the KSPIN_DESCRIPTOR struct within the PCPIN_DESCRIPTOR struct. Just a guess.
