Can't turn off sound on Clock app
Since updating to Sequoia 15.0.1 my clock app has gone weird. I usually set Timers to 30 min for exercise and at the end of that time the alarm goes off, a notification appears which can be used to silence the alarm and the Clock app can be quit.
Now there is no notification, and there is no way to switch off alarm. Have tried 'Stop Playing', 'Cancel' and even quitting the app but it just carries on.
The only way I can stop it is to go into Control Centre settings and switch sound output to 'Default' which seems to send the sound in System Settings through AirBeamTV Audio (whatever that is) but if I switch back to any of the other Output options then the sound is still playing there for ever and ever! It's still there now... please how can I make the app work, or just get rid of it?
