WAVExxxCAPS gives you 31 bytes for the device name, and just truncates if it's
longer. However, since WinXP, you can use the WAVExxxCAPS2 structure, which
will give you a name GUID. The full name is in the Windows Registry under
that GUID, located here: HKLM\System\CurrentControlSet\Control\MediaCategories
Note that drivers can report GUID_NULL for the name GUID, in which case,
Windows makes a best effort to fill in those 31 bytes in the usual place.
This info summarized from MSDN:
http://web.archive.org/web/20131027093034/http://msdn.microsoft.com/en-us/library/windows/hardware/ff536382(v=vs.85).aspx
Always look this up in the registry if possible, because the strings are
different! At least on Win10, I see "Yeti Stereo Microphone" in the
Registry, and a unhelpful "Microphone(Yeti Stereo Microph" in winmm. Sigh.
(Also, DirectSound shouldn't be limited to 32 chars, but its device enum
has the same problem.)
WASAPI doesn't need this. This is just for DirectSound/WinMM.
