Alarm: does not ring when a calendar notification starts at the same minute

[Graffrx]

Hi, When the a calendar notification starts at the same time as the clock, there ist no sound output... I'm using a nearly plain Android 10 (Fairphone 4). Google Calendar and Clock are uninstalled. Notifications are silenced. I already changed the sound output to different sound channels and not the vibration works at least. But the sound doesn't play...

if you use 2 other apps, does it work well? I dont think it is an issue in our app, those things are handled by the system

Hey, Thanks for your answer! I just tried it. The native (Google) alarm works fine.
