Overview
- 9to5Mac says some users found individual alarms’ Sound set to None, making them silent, and the scope of the issue remains unclear with only limited reports.
- The outlet advises opening the Clock app to edit each alarm, confirming Sound is set to a ringtone, and running a quick test alarm to verify audio.
- Alarms are expected to sound even when the iPhone is on silent if a tone is selected, so a silent alarm typically indicates the Sound was set to None.
- Alarm loudness is controlled in Settings → Sounds & Haptics via the Ringtone & Alerts slider, and the Change with Buttons toggle can unintentionally lower alarm volume.
- Sleep alarms use separate sound and volume controls in the Clock app, and Attention-Aware Features on Face ID devices can reduce alarm volume unless disabled.
