Audible alarm - no sound

I noticed that for some time now the alarm does not produce any sound.
The alarm is visible on the Cerbo GX, but there is no audible alarm.
The sound was working recently, so the hardware itself was functional.
The audible alarm is enabled in the settings.
All firmware/software versions are up to date.

Where should I look for the cause of this issue?

Try a reboot. It is weird it is not working
