A change in notification settings will help stop your HTC from making a noise.

We have created this easy to follow guide to help you understand why your HTC U20 keeps making a notification sound, and what methods you can execute on your mobile to fix this sound issue, so you can stop being disturbed with unnecessary alerts.
