Why Notifications Come Without Audible on Android Xiaomi and How to Fix It

Have you noticed that your Xiaomi or Redmi notifications come without sound? This is a common problem faced by smartphone users running MIUI, Xiaomi's proprietary shell. There may be several reasons, from trivial audio settings to system failures or application conflicts. In this article, we will analyze all possible causes and give step-by-step instructions on how to return sound alerts.

MIUI is a feature that actively optimizes background processes to save battery power. Sometimes this optimization is harmful - the system can block notification sounds for individual applications or completely disable them after updates. Also, the problem can lie in the settings of a particular messenger (for example, WhatsApp, Telegram or Viber), in the "Do Not Disturb" mode, or even in the hardware malfunctions of the speaker.

1. Checking basic sound settings

Before you dig deeper, make sure that the problem is not with the basic settings. Often users accidentally turn off the notification sound or turn the volume down to zero.

• 🔔 Total volume of notifications: Press the volume button on the sidebar and make sure the Notification slider is not at zero. MIUI It's separate from media and calls.
• 📱 Sound Profile: Go to Settings → Sound and vibration → Profile and select Normal (not Silent or No Sound).
• 🔕 Do Not Disturb Mode: Swipe down the notification panel and check if the cross-over bell icon is activated. → Don't disturb.

If you don't have the sound after this manipulation, move on to the next section, and especially often the problem is with the application settings that are customized, and the MIUI can reset after the updates.

2. Notification settings for specific applications

MIUI allows you to flexibly configure notifications for each application separately, perhaps the sound is turned off only for Telegram, VK or another messenger, to check:

1. Open Settings → Applications → Application Management.
2. Select a problem app (such as WhatsApp).
3. Put it on the Notifications.
4. Make sure the Allow Notifications switch is active.
5. Check if the sound in the Notification Sound section is turned off (any tune other than No Sound must be selected).

You can also set the notification priority (high, medium, low) in this menu - if it is on "low", the system can ignore the audible alerts to save battery.

Open "Settings → Applications"

Select the desired application

Activate "Allow Notifications"

Set up sound (not "No sound")

Prioritize "High"

-->

3. Battery optimization and background activity

One of the most insidious reasons is the battery optimization in MIUI. The system automatically limits the background activity of applications to reduce charge consumption, but sometimes this leads to the loss of notification sounds.

• 🔋 Go to Settings. → Battery and productivity → Battery consumption management.
• Select App Choices and find a problem one (like Instagram or Gmail).
• Set a regime for him without restrictions.

Also check the auto-run of the applications:

1. Open Settings → Applications → Application Management → Autorun.
2. Find the right application and activate the switch.

If the sound doesn’t appear after these actions, try disabling MIUI Optimization (not available on all models):

Settings → About Phone → MIUI version (shap 7 times to activate developer mode)


Settings → Additional → For developers → Disable “MIUI Optimization”

💡

After disabling MIUI Optimization, some system animations may not work properly. That's OK -- notification functionality is more important.

4.Reset notification and sound settings

If the problem is not solved, try resetting notifications and sound to factory settings, which will help if the failure occurred after updating MIUI or installing a new application.

For discharge:

1. Open Settings → Applications → Application Management.
2. Slip on three dots in the top right corner and select Reset notification settings.
3. Confirm the action.

To reset the sound settings:

1. Go to Settings. → Sound and vibration.
2. Tap it on three points. → Resetting settings.

After reset, restart your phone. If the notification sound has not recovered, move to the next section.

5. Problems with the speaker or hardware malfunctions

If the notifications are not sounded, but the music and calls are working normally, the problem is more software-based, but if all the sounds are gone (including media and calls), this may indicate:

• 🔊 Contamination speaker – dust or moisture can block sound.
• 🔌 Damage to the plume speaker (often after falls or repairs).
• 🔋 Audio chip malfunction (occurring on older Redmi models).

To check the speaker:

1. Turn on music or video – if there is no sound, the problem is hardware.
2. Connect headphones - if they have sound, but in the speaker is not, it confirms the malfunction.
3. Try to clean the speaker with a soft brush (do not use sharp objects!).

💡

If the sound is only lost for a specific application (for example, Viber), the problem in 90% of cases lies in its individual settings, not in the system.

6. Conflicts with third-party applications

Some applications (especially SEOs, antiviruses, or launchers) can block notification sounds. If a problem occurs after you install a new program, try:

• 📱 Remove recently installed apps (especially those that promise to “speed up the phone” or “save battery life").
• 🔍 Check permissions for applications in Settings → Annexes → Permits.
• 🛡️ Disable third-party antiviruses (such as Avast or 360 Security) – they often block notifications.

The problem may also be in launchers (for example, Nova Launcher or the launcher). POCO Try to temporarily return the standard launcher MIUI:

1. Open the Settings. → Home screen.
2. Select Standard Launcher.
3. Reboot the phone.

If the notification sound came up after that, it was the launcher, in which case upgrade it to the latest version or change it to another.

7. MIUI Update and Factory Reset

If neither method worked, there are two radical solutions: updating the firmware or resetting to factory settings.

MIUI Update:

1. Go to Settings → About the phone → System update.
2. If there are any updates available, install them.
3. After the update, check the sound of the notifications.

Reset to factory settings:

⚠️ Warning: This step will remove all data from your phone, including photos, contacts and apps. pre-backup through Settings → Additionally. → Backup and reset.

1. Open Settings → Additional → Backup and Reset.
2. Select Settings Reset.
3. Confirm the action and wait for the reboot.

Once reset, the phone will be like new — the notification sound should work. If the problem persists, it is almost certainly a hardware malfunction (such as damage to the audio chip).
