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

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
