IAudioClient::Reset method (audioclient.h)

The Reset method resets the audio stream.


HRESULT Reset();

Return value

If the method succeeds, it returns S_OK. If the method succeeds and the stream was already reset, the method returns S_FALSE. If it fails, possible return codes include, but are not limited to, the values shown in the following table.

Return code Description
The audio stream has not been successfully initialized.
The audio stream was not stopped at the time the call was made.
The client is currently writing to or reading from the buffer.
The Windows audio service is not running.


This method requires prior initialization of the IAudioClient interface. All calls to this method will fail with the error AUDCLNT_E_NOT_INITIALIZED until the client initializes the audio stream by successfully calling the IAudioClient::Initialize method.

Reset is a control method that the client calls to reset a stopped audio stream. Resetting the stream flushes all pending data and resets the audio clock stream position to 0. This method fails if it is called on a stream that is not stopped.
