I need to programmatically get a wave format (WAVEFORMATEX structure) of the initialized WASAPI rendering audio device. IAudioClient::GetMixFormat doesn't fit in this case, because IAudioClient::Initialize can be called with another format (not equal to the mix format). When the device is activated and initialized, what other methods of IAudioClient or IAudioRenderClient (or others?) can I call to programmatically get the actual wave format of it?

  • I know this is an old question, but did you ever find a way to retrieve the currently used wave format by the active IAudioClient? Im facing the same problem... Commented Mar 18 at 12:58
