IAMDirectSound Interface

The IAMDirectSound interface specifies which window has focus for controlling DirectSound audio playback. DirectShow provides limited support for this interface:

  • The DirectSound Renderer implements the GetFocusWindow and SetFocusWindow methods. It does not implement the other methods on the interface.
  • The Audio Renderer (WaveOut) exposes the interface but does not implement any of its methods.

In addition to the methods inherited from IUnknown, the IAMDirectSound interface exposes the following methods.
