No sound when alarm triggered

Hi there :slight_smile: Im having some problems with my Home Alarm kit. So, suddenly, the alarm/siren from the homebase stopped making sound when triggered. We get the notifications “Alarm triggered , motion detected!!” Etc etc on our phones. But NO sound/siren. Also the doorbell (Eufy) is not ringing either when someone is pushing it outside. Is like the homebase is muted… i’ve checked volumed is Max and so on, but…
