In this article, we will discuss all possible ways to return sound to notifications on Xiaomi, Redmi and other devices. POCO — From checking for obvious settings to cache resetting of system applications, we will pay special attention to the nuances of the latest versions. MIUI 14/15 And HyperOS, where the logic of sound control has changed, and you'll also learn how to customize the tunes for the sound control. SMS, WhatsApp, Telegram and other messengers.

If after reading the instructions, the sound did not work, at the end of the article there is a checklist for diagnosis and a list of alternative solutions (including radical methods such as resetting).

Why Xiaomi doesn’t have a notification sound: top-5 cause

Before we get to the settings, it's important to understand why the sound went missing, and 80 percent of the time, the problem is due to one of these things:

• 🔇 Do not disturb mode or DND (Do Not Disturb is manually or on schedule. Check the top notification bar - if there's a crescent icon, the sound is blocked by the system.
• 🎵 Notifications Volume Resets After Update MIUI In newer versions of firmware, the volume of calls and alerts is divided!
• 🚫 For example, Telegram or Viber can be removed from the list of applications that are allowed to play sounds.
• 🔄 The Android System WebView or MIUI System Launcher: These components are responsible for displaying and audible notifications.
• 📱 Hardware problem: malfunction of the speaker or headphone jack (if the sound disappears when connecting the headset).

If you’ve recently updated your firmware, the problem may be a bug in a particular version of MIUI. For example, MIUI 14.0.5 for Redmi Note 12 had a massive bug with missing notification sounds after the reboot, in which case only a rollback to a stable version or waiting for a patch helps.

Basic Notification Sound Settings: Where to Start

Start by checking the obvious parameters. Often users miss the fact that in MIUI, notification sound and call sound are regulated separately.

Open Settings → Sound and vibration. Here you are interested in three key sections:

1. Volume: Drag the Notifications slider to the right, and note that in HyperOS, this section may be called Media and Notifications.
2. Notifications: Click on this item and select a tune from the list. If the list is empty, it is a sign of a failure (solution below in the article).
3. Vibration at notifications: Turn on this switch if you want tactile recoil.

If you don't have the sound after this manipulation, check the individual settings for the apps. For example, for WhatsApp, the path is: Settings → Apps → App Management → WhatsApp → Notifications. You can turn on the sound, vibration and even set a unique tune.

💡

MIUI 15 has introduced Adaptive Sound, which automatically adjusts the volume of notifications based on the noise level around you. If the alerts are loud, then quiet, turn it off in Settings → Sound → Adaptive Sound.

Do Not Disturb Mode and Application Exceptions

One of the most insidious features of MIUI is the DND (Do Not Disturb) mode, which can be turned on not only manually, but also on a schedule (for example, overnight) or when connected to a Bluetooth device (earphones, car).

To check and configure the DND:

1. Go to Settings → Notifications and Status bar → Do not disturb.
2. Turn off the main switch if it is active.
3. Check the schedule tab – it is possible that the sound turns off automatically at a certain time.
4. In the Exceptions section, add applications for which the sound should always work (e.g., alarm clock, messages, calls).

Note the hidden setting: in some versions of MIUI, DND mode can be activated when you connect to a Wi-Fi network (such as at home or at work). To check this, go to Do Not Disturb → Rules → Connect to Wi-Fi.

Problems with system applications: WebView and Launcher

If the notification sound is gone after a system update or a new app is installed, two components may be to blame:

• 🌐 Android System WebView – is responsible for displaying web content in notifications (for example, preview links in Telegram).
• 📱 MIUI System Launcher – manages the interface and sound of notifications.

To fix the problem:

1. Go to Settings → Applications → Application Management.
2. Find Android System WebView, click Storage and select Clear Cache and Clear Data.
3. Repeat step 2 for MIUI System Launcher.
4. Reboot your smartphone.

If after cleaning the cache, the notification sound appeared, but after a while it disappeared again - roll back Android System WebView to the factory version through Settings → Apps → Android System WebView → Three dots → Remove updates.

Customization of sound for individual applications

MIUI allows you to set unique notification sounds for each messenger or social network, which is useful if you want to distinguish WhatsApp from Viber by melody.

Instructions:

1. Open Settings → Applications → Application Management.
2. Select the application you want (such as Telegram).
3. Go to the Notifications section.
4. Turn on the Sound switch and select the tune from the list. In some applications (such as Gmail), you can also adjust the vibration and the LED indicator.

For SMS and calls, the path is different: Settings → Sound and vibration → SMS notification sound or Incoming Call Sound. Here you can choose a tune from the standard ones or download your own (the file must be in.mp3 or.ogg format and be in the Ringtones folder on internal storage).

💡

If the list of tunes for notifications is empty, it is a sign of a Media Storage failure.Solution: Clear the cache and data of the Media Store application in the application settings.

What to do if the notification sound is silent or distorted

If the notifications sound but are too quiet or jammed, the problem may be:

• 🔊 Volume limitation in settings EU-Firmware (relevant to the European versions of Xiaomi).
• 🎧 Dirt in the dynamics or mechanical damage (for example, after a fall).
• 🔧 Failure in the AudioFX (standard equalizer) MIUI).

Decisions:

1. For EU-Firmware: Open Settings → Additionally. → Permits → Volume and turn off the restriction.
2. For all versions: check the speaker for physical damage. Hold the phone to your ear while playing music -- if the sound is clear, the hardware is not the problem.
3. Reset sound settings: go to Settings → System and device → Reset settings → Reset sound settings.

If distortions occur after connecting the headphones, clean the Type-C or 3.5mm (if any) jack of dust with a toothpick. Xiaomi often gets trashed by the bottom speaker, which is responsible for the sound of notifications.

💡

To check if the notification speaker is working, call the phone from another device. If the sound of the call is loud and the notifications are quiet, the problem is precisely the settings, not the hardware.
