hi all,

i have developed an audio driver, with prefix "WAV" for the 10 entry points,
it is getting loaded through the device manager and the dll is showed when i run the shell command "gi mod", and it reads as:

Welcome to the Windows CE Shell. Type ? for help.
Windows CE>gi mod
 MOD: Name pModule :dwInUSE :dwVMBase:CurZone
 M00: ceddk.dll 87f9e268 00000008 03f50000 00000000
 M01: coredll.dll 87fdf540 0000000f 03fb0000 00000000
 M02: fsdmgr.dll 87fcfef8 00000002 03f60000 00000000
 M03: regenum.dll 87f89198 00000008 03fa0000 00000000
 M04: relfsd.dll 87fa2808 00000002 03f90000 00000000
 M05: toolhelp.dll 87fa2f20 00000004 03f80000 00000000
 M06: audio.dll 87f89340 00000008 03f30000 00000000
Windows CE>

now when i run the next command "s wavplay windows\startup.wav",
the debug message says that it has not found the device driver [mr = 6] for the api waveOutOpen.

now,
i would like to know why does it say driver not found?

 - is it that my audio driver is not associated with the upper layer i.e., waveform api manager?
- or i need to load waveapi.dll first [but how], my assumption is, it is loaded runtime automatically?
- is there any registry entry to be done, so that the driver's upper layer recognizes my audio driver presence and establishes connection with it?
- is there any way which highlights about runtime binding of the drivers with their upper layers?

as of now my driver registry reads like this,
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\audio]
        "Prefix"="WAV"
        "Dll"="audio.dll"
        "Order"=dword:0

help me
regards
neo
