Notification sound in lockscreen not working

[dlaluan]

I've looked everywhere and have not found a post on this and I apologize if it has. But has anyone had any issues with their notification sounds muting in the lockscreen? Mine seem to work when my phone is open, but once it is locked, everything is muted and does not work.

Any suggestions? I'm coming from a Note 4 and have not encountered this before.

I don't have that problem but are you using one of stock notification sounds or have you changed any of them to custom sounds that you have added to your phone?
