Hi, Matt,

Oh, ok, I’ll follow your advice. I was worried about the InstallSubDevice() equivalent in AVStream.

As for the multiple (wave) devices, I guess I’ll have to make two instances of the same filter. Does that sound right to you?

Thank you for your time…

I suggest you go ahead and try adding KSCATEGORY_AUDIO to the Categories list in your filter descriptor.    That was all I had to do.

Make sure the reference string in the AddInterface entry in your INF matches the ReferenceGuid in your KSFILTER_DESCRIPTOR.

Hi, 

Right now, I am only listing KS_CATEGORY_CAPTURE and KS_CATEGORY_RENDER.

I expect that I should list KSCATEGORY_AUDIO as I do for my WavePCI drivers.

But, in the WavePCI drivers, I use "InstallSubDevice( ...., "Wave", .... );"

to link the name in the INF to my kernel mode device.

But, in AVStream I don't see the equivalent function InstallSubDevice().

What categories are you listing for your filter?

I have an AVStream driver that captures/renders audio. To do so, I use

GraphEdt and the device is listed under "WDM Streaming Devices".

Now, I need to make it also appear under "Audio Capture" devices. Can I do

this with AVStream? If so, how?

With WavePCI we use PortCls functions to expose the wave device. I want to

do the same thing using an AVStream driver.

I want to be able to use the device using the Wave API. I think it is

possible since, as far as I know, the USBAudio.sys is an AVStream driver

and

it exposes Wave devices.

Thank you
