Hello,
I see that the videos I record with the trial version have this static-y watermark, which I understand. What I don't understand is, why the videos have no sound. Is this how the trial is designed or is something wrong?
Even with the trial it will record sound. Did you check your audio tab and make sure the "Record sound" is checked as well as the correct sound device ?
If you think you setup sound correctly then go ahead and attach logs
