Modern smartphones like the Xiaomi Redmi 9 have become an integral part of our lives, providing instant access to news, messages and apps. However, the constant stream of audio signals can be annoying, especially during work hours, during meetings or relaxation. Turning off the sound of notifications is not just a matter of comfort, but a way to improve productivity by removing unnecessary distractions.
Users often face a situation where you need to leave visual notifications, but completely remove the audio. Android operating system with the shell MIUI implements many levels of sound management, which sometimes confuses device owners. Understanding the logic of these settings will allow you to flexibly manage the audio of any events on your gadget.
In this article, we will take a look at all the available methods, from simple switches to fine-tuning system settings, and learn to distinguish between system sounds, app notifications and multimedia sound, giving you complete control over your smartphone’s acoustic profile.
Use of side volume panel
The fastest way to change the audio settings is to use physical volume buttons located on the side of the body. Pressing the buttons causes the adjustment slider to appear, which by default controls multimedia volume. To change the notification settings, you need to click on the gear or tripole icon that appears next to the slider.
Once you open the extended menu, you'll see several independent scales, each of which is responsible for its own type of sound. We're interested in the bell scale, which indicates the volume of the call and notifications, and moving this slider to the far left position will completely disable the soundtrack of incoming messages and system alerts.
⚠️ Warning: A full drop in the call's volume slider can also activate Do Not Disturb or No Sound mode, which will turn off the vibration as well. Check the vibration settings separately if it should remain active.
Importantly, this is a global setting for all applications that use the standard notification channel, and if you want to leave the sound for calls but remove it for messages only, this method is not suitable and you will need to adjust more detail through the settings menu.
Customization of sounds through the system menu
For more in-depth audio profile management, you should refer to the main operating system settings menu, where you can separate the control of call sound and notification sound, which is impossible to do through the sidebar in some versions of MIUI. Go to Settings → Sound and vibration to access the necessary parameters.
In the menu that opens, you'll find a separate item that's responsible for the volume of the notifications, and by clicking on it, you can not only turn the volume down to zero, but also select an alternative sound file, such as "No Sound" or "None", which ensures that even if you accidentally change the volume slider, the sound will not appear.
Additionally, in this section, you can customize the behavior of sound when connected headphones or Bluetooth headsets. System settings allow you to create separate profiles for different scenarios of use of the device, ensuring maximum comfort.
- 🔇 Open the “Settings” menu on the main screen.
- 🔊 Go to the section "Sound and vibration».
- 📉 Find the item “Notification Volume” and set the value to zero.
- ✅ Select the melody "No sound" in additional parameters.
Managing application-specific notifications
Often there is a need to turn off the sound not for all applications at once, but only for certain, for example, for games or news aggregators, leaving important messages from messengers. → Notifications and status bar → Management of notifications.
In the list of installed applications, find the desired one and click on it. Inside the control menu, you will see the Sound switch. Disabling this switch will prevent the application from emitting any audio signals, and visual notifications (banners in the curtain) can remain active.
☑️ Checking the application settings
This method is especially useful for social networks that can make sounds when likes or comments, and you can flexibly adjust the audio stream for each software installed, creating a personalized sound environment.
⚠️ Note: Some applications have their own internal audio settings that can override system settings. Check the settings inside the application itself if the system shutdown fails.
Use of the "Do Not Disturb" mode
Do Not Disturb (DND) is a powerful tool for temporarily shutting down all audio and light signals, activated via the control center (swipe down from the top right corner) or through the settings menu, in which the phone will not emit sounds when incoming calls and notifications, except those added in the exceptions.
This mode can be configured to create a schedule for night time or work hours, for example, and the mode settings can specify which contacts or applications can break through the audio lock, ideal for those who want guaranteed silence at certain intervals.
How to set exceptions in the mode Do not disturb?
It is important to distinguish between this mode and a simple shutdown of sound. Do not disturb mode can also block the vibration and backlight of the screen, depending on the selected parameters. Flexible exception settings allow you to avoid missing really important events.
Table of comparison of methods of switching off sound
For the convenience of choosing the best way to control sound on Xiaomi Redmi 9, here is a comparative table of basic methods. It will help you quickly navigate depending on your current needs.
| Method | Coverage | Difficulty | Flexibility |
|---|---|---|---|
| Volume buttons | Global | Low. | Low. |
| System settings | Global | Medium | Medium |
| Application settings | Local. | Tall. | Tall. |
| Do Not Disturb mode | Temporary | Medium | Tall. |
The choice of method depends on how radical measures are required, with customized applications being better suited for continuous use, and DND mode being better suited for short-term silence.
💡
Combining methods gives the best result: use global shutdown for backgrounds and customized for noisy applications.
Decision and additional advice
Sometimes users are faced with a situation where the notification sound is turned on independently or not turned off by the chosen method, this may be due to updating the MIUI system or caching the settings of a particular application, in such cases, it is recommended to check whether the sound is turned on in the dialog or chat settings themselves.
Also worth paying attention to is the design theme: some third-party themes can change the behavior of system sounds or ignore standard volume settings, and returning to a standard theme often solves the problem of incorrect audio behavior.
💡
Use the Digital Well-Being feature to track which apps use audio notifications most often, and turn off the sound specifically for them.
For advanced users, a use case is available ADB-commands to force the system to change the sound parameters, but this requires a connection to the computer and the presence of appropriate drivers.
- 🔄 Restart the device after changing the system sound settings.
- 🎨 Check if the set theme of the design affects the sound.
- 📱 Make sure there are no restrictions on audio in the Security app.
