Some sounds don’t work (iOS)

If some sounds don’t seem to work on iOS (e.g. start countdown, ambient sound), you may have enabled the silenced mode (by accident). You can disable it again using the small bell icon on the control center of iOS (see screenshot).

If the bell icon is not available, read here how you can re-enable it.
