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.

Hardware-Offloaded Audio Processing

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
