Example

This sample shows the use of AcxEventGenerateEvent.

    PCODEC_MUTE_TIMER_CONTEXT timerCtx = GetCodecMuteTimerContext(Timer);
    PCODEC_MUTE_ELEMENT_CONTEXT muteCtx = GetCodecMuteElementContext(timerCtx->MuteElement);

    // Testing: update settings 0 <-> 1  
    muteCtx->MuteState[0] = !muteCtx->MuteState[0];
    muteCtx->MuteState[1] = !muteCtx->MuteState[1];
    
    AcxEventGenerateEvent(timerCtx->Event);
