The modern Xiaomi Redmi smartphone is a multimedia center that is constantly with us, but sometimes its beeps become redundant. Whether it is a meeting, a movie theater or just a desire for silence, managing the device's audio system is a basic skill. However, the interface of the MIUI shell or HyperOS offers much more options than just a volume swing on the side.
Incorrect settings can cause important notifications to be missed, or the phone to make sounds at the most inopportune moment. In this article, we will take a look at all the ways to control sound, from fast locking to deep tuning system settings.
You will learn to distinguish between Do Not Disturb and No Sound modes, and learn how to completely silence system clicks and lock sounds, which will allow you to control the audio stream of your device at a professional level.
Physical buttons and switching modes
The most obvious way to change the volume is to use side keys, and pressing the bottom of the swinger regulates the media level, and the top one increases it, but if you press the adjuster button once, a slider will appear on the screen, often with a gear or tripole icon hidden next to it.
Clicking on this extra element will open an extended menu where you can set the volume for the bell, alarm, multimedia and notifications separately, which is critical, since global silence does not always mean turning off the alarm clock.
Pressing the Power button for a long time also triggers a menu where you can quickly select "No Sound" or "Vibration" mode, and in newer versions of firmware, this switch can be pushed into the notification curtain, making it even faster to access.
- 🔊 Single press of the swing changes the volume of the active application.
- ⚙️ Pressing the gear opens the volume channel mixer.
- 🔕 Holding the power button causes an emergency sound shutdown menu.
- 📳 Vibration mode allows the phone to tremble but not ring.
It is worth noting that in some regions or on custom firmware, the behavior of the buttons may differ, for example, triple pressing the volume button can be programmed to create a screenshot or start a voice recorder, which is also worth considering when trying to quickly turn down the sound.
Setting up the "Do Not Disturb" mode
Do Not Disturb is a more advanced version of normal silence, not only turning off sound, but also blocking visual notifications, preventing the screen from turning on when incoming calls or messages, ideal for sleeping or working.
To activate this mode, open the swipe notification curtain from top to bottom and find the crescent icon. In older versions of MIUI, this item could have been called differently, but the functionality remained the same. You can set a schedule in the settings to make the phone shut down automatically at a certain time.
⚠️ Attention: Do Not Disturb mode keeps the alarm on by default. Don't rely on this mode if you want total silence, including turning off the alarm clock - it needs to be turned off separately.
An important feature is the ability to create an exception list, so you can set your phone to keep it silent for everyone except for favorites or repeat calls from a single number, a vital feature for those waiting for an emergency call.
To access the finer settings, go to Settings → Sound and Vibration → Do Not Disturb. You can allow interrupts from certain applications, making this tool a flexible filter, not just a jammer.
| Function | No Sound Mode | Do Not Disturb mode |
|---|---|---|
| The sound of the bell | Off. | Off. |
| Vibration. | Works (usually) | Off. |
| Ecran on the call. | It's on fire. | It's not on fire. |
| Alarm clock | Sounds like it. | Sounds like it. |
💡
Use Do Not Disturb mode with the Repeat Calls setting to avoid missing an urgent call if the person calls a second time in a row within 3 minutes.
Managing Systemic Sounds and Vibration
Even when the ringtone is off, Xiaomi’s smartphone can emit various clicks when dialing, screen locking sounds, or vibrations when touching the keyboard, which are often annoying to users who want complete silence.
To turn them off, you need to go to Settings → Sound and Vibration. Scroll down the list where the "Advanced" items are located or the system's sound switches are immediately displayed, and you can individually turn off the locking sound, the charging sound and the touch sound.
Vibration deserves special attention. Many users are unaware that keyboard vibration and system actions can be turned off regardless of the vibration of the call, and for this purpose, there is an item on the same menu called "Vibration on touch".
- 🔇 Screen lock sound – clicking when pressing the power button.
- 🔢 The sound of dialing - tone signals in the "bell ringer».
- ⌨️ Keyboard vibration – tactile response when printing.
- 🔋 The sound of charging – a melody when connecting the cable.
If you use a third-party keyboard, such as Gboard, its vibration settings may be inside the keyboard app itself, rather than in the phone's general settings. Check the language and input settings if standard methods didn't help.
☑️ Checking system sounds
Disabling the sound in specific applications
It often happens that the phone is in silent mode, but some application (such as a game or messenger) continues to make sounds, this is because the applications have their own audio settings that overlap the system.
In popular messengers like Telegram or WhatsApp, you go to the settings of the app itself, select Notifications and turn off the sound, which allows you to keep the phone in No Sound mode for calls, but receive quiet notifications from chats if necessary.
For games and video players, the situation is similar: on YouTube or TikTok, the volume is controlled by sliders inside the interface, which are independent of the system volume of the call. If the video is louder and the call is quieter, check the media slider.
⚠️ Note: Some apps may ignore the “No Sound” system profile when playing video if they are running in the background or have playback priority.
In Android 12 and above, as well as current versions of MIUI, the Sounds and Vibrations feature has been introduced in the notification settings for each application separately. Go to Settings → Notifications and Status bar → Notification Management, select the app and make sure that the Other Notifications category does not have audio.
Why does the sound come back after the reboot?
Use of automation and scenarios
MIUI is famous for its powerful automation tool, which is called Scripts in different versions or integrated into the Security app, and can be used to set up automatic shutdown of audio on a schedule or geolocation.
For example, you can create a scenario: "If it's between 23:00 and 7:00, turn on Do Not Disturb" mode, or a more complex one: "If I'm connected to the Office Wi-Fi network, set up No Sound mode," which eliminates the need to remember to switch modes manually.
To create a script, go to Security → Tools → Scenarios (the path may vary depending on the version of MIUI). Click Add Script, select a condition (trigger) and an action (e.g., Sound Mode → No Sound).
- 📍 Geolocation – Turning off the sound when you come to the cinema or office.
- ⏰ Time - night mode of silence on the schedule.
- 🔋 Charging – setting an alarm clock or quiet mode at night.
- 📶 Wi-Fi – Reaction to connecting to a home or work network.
Automation is the most reliable way to ensure that you don’t forget to turn off the sound. Smart scripts work even when the application is closed, as they are built into the system layer of the shell.
💡
Automation through geolocation is the most convenient way to forget about manually switching sound modes when you arrive at a certain place.
Solving problems with sound sticking
Sometimes users are faced with a situation where the sound does not turn back on or, conversely, does not turn off, despite all the settings, this can be a software failure of the audio driver or an application conflict.
First, try rebooting your device. This is a banal, but often effective, tip that resets temporary errors in the operation of the sound chip. If that doesn't work, check if there's a Bluetooth device that can intercept the audio stream.
Also worth checking is the settings of special features. In Settings → Advanced Settings → Special features may be active services that control sound (for example, hearing aids or mono-audio), which may conflict with the basic settings.
⚠️ Warning: If the sound is completely lost (even in headphones) and is not restored after the reboot, it may be damaged audio codec or speaker.
In rare cases, it helps to reset the audio settings to the factory, for this purpose, audio profiles can be restored in the engineering menu (not available on all models) or through special applications, but the average user should limit himself to restarting and updating the system.
