Hi I think I have changed a setting and I cannot find what it is but some of my notifications are not playing sound just vibrate.

 

Calls and messages seems to come through fine but email and app notifications dont seem to.

 

I have restarted my phone. I even installed the android 8.1 update hoping that might reset something. I've checked all setting I can find for notifications and they seems to be on. checked in the apps that are not working and they have "play sound" checked.

 

 

 

The phone is a Nexus 6p.

 

 

 

The only thing that come to mind is that sometimes I cannot turn DND on as the icon will just not change when I tap it. I have tried turning dnd on and off just incase it was stuck on or something.
