Samsung Alarm Not Making Sound? 8 Fixes for One UI

A Samsung alarm that makes no sound is almost always one of four settings: the alarm's own sound and volume in Clock, Clock's Silence alarms when system sound is off switch, a deleted tone, or Sleep mode. Beyond Alarm sidesteps most of them by holding the alarm volume at maximum.

The short version:

• Use Beyond Alarm: it rings on Android's alarm volume and holds it at maximum while it rings, and its reliability screen warns you if the alarm volume is at zero.
• In Clock, tap the alarm → Alarm sound: make sure it's on, pick a built-in tone, and drag the volume slider up.
• In Clock → ⋮ → Settings, turn off Silence alarms when system sound is off.
• Check Sleep mode and any Modes and Routines that run at night.
• Disconnect Bluetooth earbuds before bed, or test with them connected.

Which no-sound problem do you have?

Each symptom points at a different setting. Start with the row that matches your morning.

If the alarm doesn't go off at all, not even a vibration or a screen, that's a different problem: see why a Samsung alarm doesn't go off.

A note on menu names

The paths below follow Samsung's own support pages and One UI 6 and 7. Samsung renames and moves things between versions, so if a path doesn't match, use the search bar at the top of Settings, or the ⋮ menu inside Clock, and look for the words in bold.

1. The alarm's own sound and volume, in Clock

On a Samsung phone the alarm's loudness lives in the Clock app, not the main volume sliders. Samsung's guide to Settings → Sounds and vibration → Volume describes sliders for "call ringtones, notifications, media, and system sounds". Turning those up doesn't reach a Clock alarm.

1. Open Clock, tap the alarm, and check Alarm sound is switched on. If it's off, the alarm only vibrates.
2. Tap the words Alarm sound (not the switch). Samsung's alarm guide says to "choose a sound to play for the alarm and drag the slider to set the volume".
3. Tap Save. Each alarm keeps its own volume, so check every alarm you rely on, not just one.

Newer phones add a shortcut. Samsung's Galaxy S25 page shows Clock → ⋮ → Settings → Volume, where you can set one volume for every alarm instead of one per alarm.

Third-party alarm apps work differently: they play on Android's alarm volume. If that's at zero, their alarms are silent. If yours rings but is too quiet, why alarms are too quiet on Android covers gradual volume and the other causes.

2. "Silence alarms when system sound is off"

This is the Samsung-specific one, and it explains most "it only rings when the phone isn't on Vibrate" stories. Samsung's support page says you "can also silence your alarms when your device's sound is turned off".

1. Open Clock and stay on the Alarm tab.
2. Tap ⋮ (More options) → Settings.
3. Turn off Silence alarms when system sound is off.

With it on, switching the phone to Mute or Vibrate at bedtime also silences every Clock alarm. Samsung suggests changing the sound mode rather than using the volume buttons to keep your levels, which is the habit that makes this switch matter.

3. A deleted or moved tone

If the alarm tone is a song or a file you downloaded, it depends on that file still being there. Move it, delete it, or clear out your music app's offline downloads, and the alarm can point at nothing.

1. In Clock, tap the alarm → Alarm sound.
2. Pick one of Samsung's built-in tones.
3. Set a test alarm two minutes ahead and listen.

4. Bluetooth earbuds and speakers

Samsung's volume guide notes that "an additional volume level will show for audio devices connected through Bluetooth". With earbuds or a speaker connected overnight, the sound may not go where you expect: one owner in the Samsung Community reports "still hearing notification and alarm sounds in my earbuds".

How this behaves depends on the phone, the earbuds and the One UI version, so don't guess. Either turn Bluetooth audio off before bed, or set a test alarm with your earbuds connected and listen to where it plays.

If you wear a Galaxy Watch, Samsung says that when the two are connected, "alarms set on your phone will sound on both devices", so the watch shouldn't take the sound away from the phone.

5. Sleep mode

Sleep mode can switch on by schedule every night, and it carries its own Do Not Disturb settings. Samsung's alarm guide sets it up from Clock → ⋮ → Set Sleep mode schedule, and it can turn on automatically.

1. Open Settings → Modes and Routines → Modes → Sleep.
2. Open its Do Not Disturb settings and make sure Alarms is allowed.
3. Do the same for any other Mode that runs at night.

Even with alarms allowed, owners in the Samsung Community have reported silent alarms in Sleep mode after updates. Samsung's suggested next step there was testing in Safe Mode to rule out another app. The three ways Do Not Disturb silences an alarm covers the rest.

6. Routines (Bixby Routines) that change the sound

Modes and Routines, called Bixby Routines on older phones, can lower volumes, change the sound mode to Mute or turn on Do Not Disturb at a set time. Combined with section 2, a bedtime routine that mutes the phone also mutes the alarm.

Open Settings → Modes and Routines → Routines and read every routine that runs at night. Check what it changes, and whether it switches back in the morning.

7. If it's Samsung's own Clock: update it

If the sound stopped after a software update, members of the Samsung Community report that updating Clock from the Galaxy Store fixes it. Open Galaxy Store → Menu → Updates and update Clock if it's listed.

8. Beyond Alarm: a Samsung alarm that can't ring silently

If you've been caught by any of the above, the simplest fix is an alarm that doesn't depend on how the sliders were left. That's what we built Beyond Alarm to do.

Beyond Alarm's reliability screen also checks the alarm volume, exact-alarm permission, notifications, full-screen alerts, battery optimisation and Display over other apps, and opens the right page for each. On Samsung, also add it to Never sleeping apps, as our Samsung alarm checklist explains. Not sure which failure you had? Start with why your alarm didn't go off.

Test it before you rely on it

Set an alarm for three minutes from now, put the phone on Vibrate the way you would at bedtime, lock it and put it face down. If it rings out loud, the Clock settings are right.

Then check what a three-minute test can't: that no Mode or Routine switches on at night, and that your earbuds aren't connected. Re-check after any One UI update.
