Example

Example usage is shown below.

    ACX_MUTE_CALLBACKS              muteCallbacks;
    ACX_MUTE_CONFIG                 muteCfg;
    ACXMUTE                         muteElement;

    //
    // Create three elements to handle mute for the audioengine element
    //
    ACX_MUTE_CALLBACKS_INIT(&muteCallbacks);
    muteCallbacks.EvtAcxMuteAssignState = CodecR_EvtMuteAssignState;
    muteCallbacks.EvtAcxMuteRetrieveState = CodecR_EvtMuteRetrieveState;

    ACX_MUTE_CONFIG_INIT(&muteCfg);
    muteCfg.ChannelsCount = MAX_CHANNELS;
    muteCfg.Name = &KSAUDFNAME_WAVE_MUTE;
    muteCfg.Callbacks = &muteCallbacks;
