Alarms silent on iOS 12 and iOS 13

Hi. I have a problem with alarms being silent, after snoozing it for one time on iOS12, and currently iOS13. I don’t know why is this happening? I usually mute the device, since I know the alarms are supposed to work even then, but after I snooze it once or twice, it just goes off silently. What is the problem behind this?

Hey there!
The problem could be in the default time for the snooze
