Modern Xiaomi and Redmi smartphones have become an integral part of our lives, providing instant access to news, messages and games. However, the constant stream of beeps can be annoying, especially during important meetings, watching movies or having a night out. Users often look for ways to quickly and effectively turn off the sound of notifications to keep concentration or just enjoy silence.
With an Android operating system with a MIUI shell or HyperOS, there are many layers of audio alert management, so you can jam the entire device, set up Do Not Disturb mode, or selectively turn off sounds for specific applications, such as Telegram, WhatsApp, or system services, and understand these settings allows you to flexibly manage the acoustic profile of the gadget.
In this article, we will take a look at all the available sound management techniques, and we will look at both the standard system tools and hidden settings that will help you adjust the perfect balance between informativeness and silence, so you no longer have to manually turn down the volume with buttons on the case.
Use of physical buttons and quick settings
The fastest way to change your sound profile is to use hardware volume buttons, and clicking on any of them causes an adjustment slider, which often has a gear or arrow icon next to it, and by clicking on it, you get access to an extended menu where you can separately adjust the volume of the media, the call and, importantly for our theme, the notifications.
If you need to turn off your phone instantly, the easiest way to use the notification curtain is to swipe down from the top to open the control panel and find the speaker or bell icon. The sound mode switch lets you choose the "No Sound" or "Vibration" option, in which Xiaomi will stop making any sounds, but will vibrate when incoming calls or messages, if this feature is not disabled.
⚠️ Warning: No Sound mode can block alarm clocks on some firmware versions, so check your timer or alarm settings separately before going to bed.
Also available in the curtain is the Do Not Disturb mode (moon icon), which hides not only sounds but also visual notifications on the locked screen, skipping only calls from selected contacts, ideal for deep concentration or night sleep, when even vibrations may be unwanted.
Deep adjustment of sounds in the system menu
To fine-tune it, you need to go to the main settings menu. Open the settings and find the Sound and Vibration section. This is the basic toolkit for managing the audio of your device. Unlike the quick panel, you can set the behavior of your phone in different scenarios.
Inside the Sound and Vibration section, find the Notification Sound. Clicking on it will show you a list of available tunes. Scroll down the list and select No or No. This action will set a global stub for all standard system alerts. However, many modern applications use their own notification channels that may ignore this setting.
Special attention should be paid to the “Additional settings” section inside the audio menu, where you can find options for controlling lock, charge and even keyboard sounds. Disabling touch and lock sounds also contributes to the overall silence of the device, making it less noisy.
☑️ Checking the sound settings
Remember that changes to the system menu apply to all applications that do not have their own priority settings. If after resetting the sound to “No”, you still hear signals from messengers, then they need to be customized individually within the applications themselves or through notification management.
Managing Notifications for Individual Applications
The most common cause of annoying sounds is active messengers and social networks. MIUI and HyperOS have an advanced notification management system that allows you to flexibly configure each application. To access these settings, go to Settings → Notifications and Status bar → Notification Management.
In the list that opens, find the app you want, like Viber or Instagram. Click on the name to reveal the details. Here you'll see the Allow Notifications switch. If you turn it off, the app will stop bothering you at all. However, if you want visual notifications without sound, select Sound and set No Sound.
- 📢 Important Notifications: Some marked as important notifications may ignore Do Not Disturb mode. Check if the Important Notifications option for specific applications is enabled.
⚠️ Warning: Turning off the sound for the System Security or Downloads app may cause you to miss the completion of a file download or the antivirus warning.
This approach allows you to leave the soundtrack for important work chats, but completely remove the sounds from games or news feeds, and it creates a personalized sound environment where you hear only what is really important.
Secret to Quiet Notifications
Do Not Disturb and Schedules
The Do Not Disturb (DND) feature on Xiaomi smartphones is a powerful tool that is often underestimated. Unlike simple silent mode, DND allows you to create exceptions and automatic schedules. You can find it in the Settings menu → Sound and vibration → Do not disturb.
The main advantage of this mode is that you can set time slots, for example, from 23:00 to 07:00, when the phone automatically goes to quiet mode, which eliminates the need to (manually) switch settings every night, and you can set the repetition by day of the week, which is convenient for working days.
An important aspect is setting exceptions. Even in silent mode, you can allow calls from certain contacts (like "Favorites") or re-calls. If someone calls you a second time within 3 minutes, the system will miss the call, considering the situation an emergency, which provides a balance between availability and peace.
| Parameter | Description of action | Recommendation |
|---|---|---|
| Schedule | Automatic time-onsetting | Set for sleep. |
| Media sound | Stunned video and music | Leave it on. |
| Visual effects | Screen blinking at notifications | Turn it off for savings |
| Repeated calls | Missing a call when repeated | Leave it on. |
Using schedules is the best way to forget about the problem of sudden sounds at night or during regular meetings, and the system will take control of the audio modes based on your timekeeping.
💡
Automating Do Not Disturb mode through schedule is the only guaranteed solution for a quiet sleep without the risk of missing an emergency call.
Disabling system sounds and MIUI advertising
Xiaomi users often encounter not only app notifications, but also the system sounds of the shell itself, which can be unlocked, charged, screenshots, or even sound ads in system applications, which can be removed, but the paths to these settings are sometimes hidden.
To turn off the interface sounds, go to Settings → Sound and Vibration → Additional Settings (or “More”). This is where the switches for Locking Sounds, Touch Sounds, and Choice Sounds are located, and disabling these options will make the interaction with the phone completely silent, except for multimedia and calls.
Special attention should be paid to advertising and recommendations in system applications, which are often accompanied by an audible signal. To turn this off, you need to go to the Security app, click three dots in the corner, select Settings and turn off "Get recommendations." Similar actions are required in the Music, Video and Explorer applications.
- 🛡️ Security: Settings (cogs) → disable "Receive recommendations».
Once these actions are done, the number of foreign sounds will be significantly reduced, and the system will behave more "sterile" and predictable, without drawing attention to the background processes.
💡
If the sound comes from an unknown application, at the time of its appearance, lower the notification curtain - the name of the sound source will be indicated there.
Solving problems with hanging sounds
Sometimes the notification sound sticks or plays back constantly, even if you have already closed an app or read a message. This is a software glitch that is common with some MIUI-based Android versions.
The first step should be to reboot the device.This is a standard procedure that clears RAM and resets the hung audio service processes. If the reboot didn't help, try clearing the problem app's cache through the App menu → All Apps → Selected App → Memory → Clear the cache.
In more complicated cases, when sound is played in the background without a visible source, a safe mode can help: press the off button, and when the off icon appears on the screen, hold your finger on it. The phone suggests that you go to safe mode. If the sound is lost in this mode, then it is the fault of the third-party application that needs to be found and removed.
⚠️ Note: Do not attempt to delete system sound files through a file manager without root rights – this can result in complete system audio loss or cyclical restart.
If the problem is massive and appeared after the firmware update, it makes sense to wait for a patch from the manufacturer or roll back to the previous version of the software, if such an opportunity is provided for your model.
