Alarm on iPad doesn’t work

I have missed a meeting due to my alarm clock suddenly stopped working. I have 8 alarms set for morning for every five minutes, each of those has sound set to a specific song i have downloaded on iMusic. It worked miraculously for years. And suddenly - stopped. I have tried all the troubleshooting steps i found on the internet - “change sound volume with buttons”, on and off, too. I have the sound in an alarm set to a specific song, so the “set to none” option does not apply here. I have an updated iOS, tried rebooting the device. Nothing has helped. I would like to avoid resetting my whole device. What can i do to make my alarms work again?
