You're going to have some challenges replacing wdmaud.drv. You're trying to
use what I call the NT4 driver model which has been deprecated for non-MIDI
audio drivers since sometime around 1998 (with the advent of the WDM driver
model). In particular, starting with Windows Vista the hooks for the mixer
driver aren't supported at all (and the wave hooks are only supported because
the TAPI component in Windows depends on it for certain classes of telephony
applications).
You should seriously consider switching to the WDM driver model for your audio
driver.

Subject: [wdmaudiodev] I need to use my driver instead of wdmaud.drv
Hi, All! I have written audio installable driver and very specific "hardware"
audio driver. I want to use my installable driver instead of wdmaud.drv, but OS
Windows (2000+SP4, XP+SP2) not uses my driver! What specific requirements exist
for audio installable drivers? This is my inf file:
-----<BEGIN

Class=MEDIA
ClassGUID={4d36e96c-e325-11ce-bfc1-08002be10318}

mysys.CopyList = 10,system32\drivers
mydrv.CopyList = 10,system32

my_aud.sys = 1
my_drv.drv = 1
[Manufacturer]
%MfgName% = models
[models]
%DeviceDesc%=mydevice, USB\VID_XXXX&PID_XXXX&MI_XX
[mydevice]
CopyFiles=mysys.CopyList, mydrv.CopyList
AddReg = mydevice.AddReg
[mydevice.Services]
Addservice = my_aud, 0x00000002, my_Service
[my_Service]
DisplayName = %MY_SDesc%

StartType = 3
ErrorControl = 1
ServiceBinary = %10%\system32\drivers\my_aud.sys
LoadOrderGroup = Extended Base
[mysys.CopyList]
my_aud.sys
[mydrv.CopyList]
my_drv.drv
[mydevice.AddReg]

HKR,Drivers\mixer\my_drv.drv,Driver,,my_drv.drv
HKR,Drivers\mixer\my_drv.drv,Description,,%DeviceDesc%
[Strings]
...
----->END
My "hardware" driver installs and works through DeviceIoControl well. However,
Windows not sees my installable driver, and I can't to use waveAPI!
