Hi

I write a audio driver with Multiple Audio Subdevices. I defined two
subdevice "wave1, wave2", and the FriendlyName is "Punch, Judy". When I run
driver under window2k, I can find the friendly names "Punch, Judy"in the
audio control panel.
When I run driver under windowsXP, I can't find the friendly name in audio
control panel, only the driver name.

I need use "friendly name" in user mode program, How can I use "friendly
name" under windows XP?


Fellow is DDK document:

First, your adapter driver should expose each stereo subdevice as a separate
instance of a port/miniport pair during the startup sequence. Several of the
sample adapters in the DDK implement an InstallSubdevice function that
creates and registers a subdevice consisting of a system port driver, a
miniport driver, and a set of resources that are to be bound to this pair.
During startup, your driver should call its InstallSubdevice function once
for each stereo subdevice and specify a unique name for each port/miniport
pair.


In addition, the unique name you assign to this pair must match the KSNAME
string that you specify in your driver's INF file. For example, your driver
might assign the names "Wave1" and "Wave2" to two subdevices during startup,
as shown below:
InstallSubdevice(..., "Wave1",...);
InstallSubdevice(..., "Wave2",...);In this case, the same names should
appear in the INF file:

KSNAME_Wave1="Wave1"
KSNAME_Wave2="Wave2"Your INF file should add interfaces that contain these
names:

AddInterface=%KSCATEGORY_AUDIO%,%KSNAME_Wave1%,Tes t.Interface.Wave1
AddInterface=%KSCATEGORY_AUDIO%,%KSNAME_Wave2%,Tes t.Interface.Wave2The INF
file should create AddReg sections in order to add information about these
interfaces to the registry:

[Test.Interface.Wave1]
AddReg=Test.I.Wave1.AddReg
[Test.Interface.Wave2]
AddReg=Test.I.Wave2.AddRegThe AddReg sections should also specify the
registry entries for each subdevice:

[Test.I.Wave1.AddReg]
HKR,,CLSID,,%Proxy.CLSID%
HKR,,FriendlyName,,%Test.Wave1.szName%
[Test.I.Wave2.AddReg]
HKR,,CLSID,,%Proxy.CLSID%
HKR,,FriendlyName,,%Test.Wave2.szName%Finally, the INF file should define
the friendly names for these subdevices:

Test.Wave1.szName="Punch"
Test.Wave2.szName="Judy"
