I recently updated my Samsung Galaxy S3 from Cyanogenmod 11.x to the latest 13.0. Despite some transitional issues, everything seemed fine.
Except that I almost overslept because the alarm was silent; only the vibration went off.
I have been through all the settings and combinations of modes (airplane mode, system profile, ...) -- volume is turned up everywhere but alarms are always silent. What do I have to do?
I use the system clock/alarm app.
