The IAMTVAudio interface is implemented on the TV Audio filter. This interface enables applications to control settings unique to audio from television sources, including secondary audio program (SAP), and stereo or mono selection. These controls are generally found on devices external to the system audio mixer.
In addition to the methods inherited from IUnknown, the IAMTVAudio interface exposes the following methods.
|get_TVAudioMode||Retrieves the current TV audio mode.|
|GetAvailableTVAudioModes||Retrieves a bitmask of the possible modes.|
|GetHardwareSupportedTVAudioModes||Retrieves a bitmask of the formats available in the hardware.|
|put_TVAudioMode||Sets the current TV audio mode.|
