<div>Hi Axel ,</div>
<div> </div>
<div> Your log showing that there is some performance issue when you record audio/video both , as it is dropping the audio samples , and due to those dropped samples you are listening that choppy sound or no sound at all . </div>
<div> </div>
<div> Try recording video at lower resolution (176x144) , this may make things better . </div>
