HTC 820S Ringtone problem

[AC Question]

When I receive a phone call or a sms text message the phone will vibrate only, it won't play any ringtone, but the sound/speakers work as I can play music and listen to videos, now when someone calls me on the phone won't play ringtone

Welcome to Android Central! Go to Settings>Sound & Notifications>Ringtone, and select any of the ringtones. Does it play a sample for you?
