Recently notification-sounds have started playing even when set to silent and/or DoNotDisturb.
The sounds seem to be played through the media channel as the volume can be changed by adjusting media-volume.
Even weirder is that it for some reason plays a sound for every notification again everytime i get a new one. Imagine an echo effect.
I deinstalled apps i installed around the time the issue started. The malware-scan shipped with the S7 couldn't find anything. No priority-exceptions are set for notifications. (I of course also restarted the device)
When booting in safe mode the notification sounds behave normally. I believe it could be some kind of malware which imitates notification sounds.
Does anyone know how i could troubleshoot such an issue? I want to avoid resetting my Phone or deinstalling every app until i find the correct one.
Is there perhaps a way to monitor apps currently playing audio i don't know about?
Thanks in advance
Device: Samsung Galaxy S7 (Updated)
