You should send this message to a device ID instead of a device handle.

Subject: [wdmaudiodev] Anyone tried using
DRV_QUERYDEVICEINTERFACE[SIZE]?
Has anyone tried sending the DRV_QUERYDEVICEINTERFACESIZE message to a
wave
device? I tried using it (and its companion, DRV_QUERYDEVICEINTERFACE)
on
two Windows XP systems (one "Gold", one SP1), and they both seem to
return
MMSYSERR_NOTSUPPORTED (8). Both devices queried used WDM Audio drivers;
one
driver was signed and one driver was not signed. I tried both wave in
and
wave out devices.
Any ideas? A fragment from my test program is pasted below. I am
probably
missing something obvious.
Best regards,
-Dan
