I cannot hear my sound when text messages when there delivered to my phone

[AC Question]

All other notification sounds work fine. Only thing not making sound is text messages. In or out of a conversation. All volume is turned up in settings for notifications. When i try to change the notification tone, i can not hear the sample either. I can hear the sample from settings. Where it shows me my tone. I have a galaxy S6
