Indeed. Odd that it works with 1.15.1 then, since the problem is that 
Windows is returning a different IMMDevice pointer for the default 
device query. This should actually be causing a buffer overrun in 1.15.1 
since it only allocated enough space for the number of reported devices, 
while the default would get added twice.

So then I wonder what's the correct way to test if two IMMDevices refer 
to the same endpoint. The device ID is a stringified UID of some kind, 
which theoretically can be equal even if a case-insensitive compare 
fails. MSDN also says apps should treat the ID string as 'opaque', and 
not try to parse it since it can change between systems.
