I am using KS and my first attempt was to leverage the
KSPROPERTY_AUDIOENGINE_SUPPORTEDDEVICEFORMATS but it does not look like it
returns what I was expecting

What API are you using to stream?
If you’re using WASAPI, you can call IAudioClient2::SetClientProperties(…) and
then IAudioClient::IsFormatSupported(…).
If you’re using KS, you can look at the data ranges exposed by the offload pin
factory.

So how to discover offloaded formats?

To find out the supported formats, you need to enumerate all possible formats
and ask the device (driver) whether
the format is supported or not. But I have no idea what “offloaded” means ?

Hi Audio
Is there a way to list all supported formats of an audio device and find out
which can be offloaded?
Thanks in advance
Andrew
