HiCan you provide you USB Audio Device's Configuration descriptor? I guest your
USB Audio Device report output terminal type is Headphone. Basically you can
not change Endpoint type by INF.

KSNODETYPE_SPEAKER, but it doesn’t seem to have any effect. It still shows up
as headphones. Installed same inf for USB speaker, and it keeps its Configure
button enabled. Here below is my inf file for reference. Note that I don’t
copy and register my APO with inf, I have a separate installer for that.

APO_FLAG_SAMPLESPERFRAME_MUST_MATCH helped. Now I receive 6 channels in
IsInputFormatSupported. Thanks for helping with this. I noticed that
“Configure” button for my USB device is grayed out. So, I can’t select
preferable speaker configuration (Stereo, Quad, 5.1 etc) in Speaker Setup

make supported speaker configurations available for user to choose from? Thank

Set a breakpoint on your IAudioProcessingObject::IsInputFormatSupported
implementation If you’re using CBaseAudioProcessingObject, you will need to
modify your flags. The default flags have APO_FLAG_SAMPLESPERFRAME_MUST_MATCH.
This will reject any attempt to pair an input format and an output format with
a different number of channels. // audioenginebaseapo.h enum APO_FLAG {
APO_FLAG_NONE = 0, APO_FLAG_INPLACE = 0x1,
APO_FLAG_SAMPLESPERFRAME_MUST_MATCH = 0x2,
APO_FLAG_FRAMESPERSECOND_MUST_MATCH = 0x4,
APO_FLAG_BITSPERSAMPLE_MUST_MATCH = 0x8, APO_FLAG_MIXER =

Subject: [wdmaudiodev] Re: Multichannel audio USB support I see, you want to
provide custom downmixing. You can do this by implementing an SFX APO that
supports both stereo and multichannel input, and always outputs stereo. Your
driver package will have an .inf and a .dll in it; no need for a custom .sys.
Media players will call IAudioClient::IsFormatSupported(…) with the source
content. If the source is multichannel, this will succeed, and your custom
downmixing will be in effect. (To be complete, I will mention that whether
IAudioClient::IsFormatSupported is called depends on the particular API the app
is using to stream. Some legacy APIs will open in the mix format regardless of
the source content. For those apps, your SFX will be opened in stereo mode.)

Subject: [wdmaudiodev] Re: Multichannel audio USB support The resulting audio
device will support multichannel input through downmixing it into stereo in
SFX. The downmixing is done the way it preserves sound localization by use of
binaural/HRTF techniques. So apps are free to choose multichannel output on
that device. From: wdmaudiodev-bounce@xxxxxxxxxxxxx

To be clear on what exactly I need, let me describe it from the user
perspective. I want a USB audio device to show up as supporting multichannel
input, such as 5.1 or 7.1, so that user can configure it from Speaker Setup
control panel. Internally, per my understanding, this will mean downmixing
multichannel input into stereo in SFX to match USB headset stereo output.
If the hardware does not support 5.1 or 7.1, why would you want to pretend that
it does? That's just going to produce a confusing user experience. Apps will
assume they can exploit the additional channels.-- Tim Roberts,
