Why is my phone alarm silent when other sounds work?

Start with the alarm’s own settings rather than assuming the phone’s general sound level controls it. In Google Clock on Android, there is an Alarm volume slider, a setting for choosing an alarm sound or song, and controls for selecting repeat days or pausing an alarm. Check that the volume is raised, a sound is selected, and the alarm is active for the day you need it. Google also notes that a silent ringtone with vibration turned off can prevent an alarm from going off. These details apply to Google Clock; another app or phone may organize its controls differently. [S1]

For a quick first pass, open the alarm you expect to ring and inspect its settings one by one. Don’t change several things at once: identifying the specific setting that was off makes it easier to verify the fix.

Check whether that alarm is set to repeat on the day you expect, or whether it has been paused. Google Clock’s settings include controls to repeat on selected weekdays or pause an alarm, so an alarm can appear familiar while its schedule does not match your plan. [S1]

For example, suppose you expect a weekday alarm on Tuesday. Confirm that Tuesday is included in its repeat days; if it is a one-time alarm instead, confirm that its displayed date and time are the ones you intend. Those are example checks, not a claim about how every alarm app displays dates. If you have multiple alarms, inspect the one with the matching time rather than assuming a different alarm is active.

It could, depending on the phone and settings. Android’s Modes and Do Not Disturb settings can include a filter called “Alarms & other interruptions,” where alarms may be allowed or blocked. Check that filter while the relevant mode is active. [S2]

Google Clock also directs users to review Do Not Disturb if it silences an alarm. [S1] The exact steps and behavior can vary by phone, manufacturer, and alarm app; the Android guidance does not establish identical behavior on every device. [S2] If you don’t see an alarms filter, look in your phone’s own Modes or Do Not Disturb settings, and consult the help for your alarm app rather than assuming the setting works the same way everywhere.

Use a short, low-stakes verification: set a temporary alarm for a few minutes ahead, confirm its sound and volume, and observe whether it rings. This is a practical check, not a guarantee that the regular alarm will behave identically under every condition. If you rely on an alarm for an important event, keep another suitable way to wake yourself while you investigate.

Here is a copyable example for a simple check:

1. Set a temporary alarm a few minutes ahead.
2. Select an audible sound and raise the alarm-specific volume if available.
3. Check that the alarm is active and not paused.
4. Review whether the current Do Not Disturb or Mode allows alarms.
5. Note whether the test rang and which settings you checked.

If the test is still silent, record your phone model, the alarm app, and the settings you inspected, then use the device or app’s support instructions. This guide cannot identify which setting is responsible on every phone; settings and behavior differ across devices and apps. [S1] [S2]
