Conceptually, an audio session (IAudioSessionControl) is an (app, endpoint)
pair.
An app can have zero or more active streams (IAudioClient) on a given endpoint
at any given time.
The stream has an associated WAVEFORMATEX (what was passed to
IAudioClient::Initialize) but there’s no way to retrieve it from the
IAudioClient.
There is also no way to get the list of active IAudioClients from an
IAudioSessionControl.
What is the larger problem you’re trying to solve?

Hi,
Is it possible to retrieve the audio session format (WAVEFORMATEX) from a given
pointer to an active IAudioSessionControl?
Thank you,
Dadi
