How to remove the sound of charging connection on Xiaomi Redmi Note 8 Pro

Smartphones line Redmi has long established itself as a reliable device, but the proprietary shell MIUI, And they have a lot of little parts that can be annoying to users, and one of those features is the loud system sound that you hear every time you plug in a power cable or a power cable. USB-For many owners of Xiaomi Redmi Note 8 Pro, this sound signal becomes a real test of nerves, especially if the device is used as a navigator in the car or a night alarm when unnecessary noise is categorically inappropriate.

The problem lies in the fact that the standard menu of sound settings in the shell MIUI Often does not contain a separate slider or switch, responsible solely for the system sounds of the connection, users are forced to look for workarounds to drown out this obsessive squeak. In this article, we will discuss in detail all known ways to solve this problem: From simple volume manipulation to the use of advanced tools such as ADB-team.

It is important to understand that completely removing the system file responsible for sound requires superuser rights (Root), which is not always secure and can lead to a loss of warranty. However, there are less radical methods that allow you to achieve the desired result without deep interference with the file system, and we will consider these as a priority, starting with the most secure options.

Why Redmi Note 8 Pro makes sound when charging

The system logic of Android, and in particular the MIUI shell, is built on constantly notifying the user of the state of the device. The sound of the cable connection is not just a melody, but a system event that the operating system treats as an important action. When you insert the plug into the connector, the power controller sends a signal to the processor, which in turn activates the corresponding audio file. This is done to let the user know: contact is established, charging is started, the device is safe.

However, in the Redmi Note 8 Pro model, as in many other Xiaomi smartphones, the volume of this event is by default tied to the overall volume of the media or system, but often has its own threshold. Even if you minimize the ringtone sound, you can hear a characteristic click or trill when you connect the cable.This is because Android is considering connectivity. USB high-priority event.

And then there are different types of connections that cause different system reactions. USB-A computer port or power bank can be accompanied by a variety of beeps, and understanding the nature of these signals helps you choose the right way to turn them off.

⚠️ Warning: Attempting to delete system files without backing up can lead to unstable operating system operation or a cyclical device restart.

Basic volume settings and operating modes

The easiest and safest way to remove the connection sound is to manipulate the volume profiles. Although there is no direct USB Sound switch on the standard menu, you can try to trick the system by redirecting your priorities. Go to the Settings → Sound and Vibration menu. Here you will see a few sliders. Try to keep the volume of System Sounds to a minimum. In some versions of MIUI, this helps to drown out the squeak when you connect.

Another effective method is to use Do Not Disturb mode, which blocks most audible notifications, including system notifications, and to activate it, lower the notification curtain and click on the appropriate icon, but this method has a significant disadvantage: you will also stop hearing calls and messages, which may not be acceptable during daytime.

• 🔇 Slider "System sounds" in the settings sometimes hides the desired parameter, check it carefully.
• 🌙 Do Not Disturb is guaranteed to remove the sound, but also blocks incoming calls.
• 🔌 Turning off vibration sound when connected may also be required for complete silence.

It is worth noting that on different versions of firmware (Global, China, EEA), the location of elements may differ, and if standard sliders do not help, then the sound is rigidly spelled out in the logic of the drivers and requires a deeper approach.

Using third-party applications for sound management

If the standard Xiaomi Redmi Note 8 Pro tools fail to drown out the peeping, apps from the Google Play Store come to the rescue. There is a class of utilities that allow you to manage individual Android audio channels. One of the most popular and functional solutions is the “Volume Control” application or its counterparts, such as Samsung’s “Sound Assistant” (you can install on Xiaomi).

The principle of these programs is to create a virtual audio control layer, which intercepts system commands and allows you to set the volume for specific events to zero, even if the system slider shows a different value, and after installing the application, you need to give it the necessary permissions, including access to change system settings.

In the app settings, find the section responsible for system sounds or USB events. Set the volume for this event at 0%. This will keep the media and ringtones high, but make charging silent.

💡

When installing audio management applications, read permissions carefully. Do not give access to contacts or location if the application claims only audio control.

There are also automating applications like MacroDroid or Tasker, which can create a script that says, "If event = Power, action = Media Volume at 0." In 2 seconds, you can turn the volume back up, which is a complex but very flexible method.

⚠️ Warning: Third-party apps can consume extra battery power in the background, which is critical for budget models, although the Redmi Note 8 Pro has a capacious battery pack.

Disconnecting the sound through the engineering menu and ADB

For advanced users who are not afraid of the command line, there is a method of turning off the sound through ADB (Android Debug Bridge), which does not require Root rights, but requires connecting the smartphone to the computer. First you need to activate the developer mode. To do this, go to Settings → About phone and quickly click on the build number seven times (MIUI Version).

Once you activate Developer Mode, go to Advanced Settings → For Developers and turn on “Debugging USB.” Now connect your phone to your PC with a cable. Your computer should have Android SDK Platform-Tools installed. Open the command line in the ADB tool folder.

adb shell settings put global sound_effects_enabled 0

This command disables all system sounds on the interface, including keyboard clicks and often connection sound. If you want more point-based exposure, you can try commands that change the audio stream parameters, but they depend on the specific version of Android.

There is also a myth about the engineering menu (#6484##) where you can supposedly turn off sound tests. However, in modern versions of MIUI, this menu is only for diagnostics and does not contain settings for permanently disabling system tunes. Don't try to change the parameters in the engineering menu without knowing exactly what they are.

System sound analysis and file system

The most radical, but also the most effective, method is to delete or replace the audio file itself. All Android sounds are stored in the system partition. These will require Root rights and a file manager with access to root folders, such as Root Explorer or MT Manager. The path to sounds is usually: /system/media/audio/ui or /system/media/audio/notifications.

You need to find the file that connects to you. It's often called ChargingStarted.ogg, usb_connect.ogg or dock.ogg. Before you delete a file, make sure to make a copy of it! then replace the original file with an empty sound file (silence.ogg) or simply rename the original by adding the.bak extension.

Once you replace the file, you have to restart the device, if the sound is gone, the operation is successful. If the phone goes into a cyclic restart, you have to restore the file through Recovery mode or reflash the device.

Features of work in the mode of the car and navigation

Many Redmi Note 8 Pro users use a smartphone in the car, in which case the connection sound can interrupt navigational prompts or interfere with the conversation on speakerphone. MIUI has a special In-car mode that can be activated through scenarios in the Safety app or through special features settings.

When this mode is activated, the phone can automatically go to Do Not Disturb mode or turn on speakerphone, ignoring system sounds, and you can also set up automation: when you connect to the car's Bluetooth headset, start the desired sound profile, a software solution that does not require changing files.

If you use your smartphone as a navigator connected to charging constantly, it is best to use the method of replacing the system file or ADB-team, as the constant clicks will be very tiresome on a long trip.

⚠️ Warning: When using your smartphone in your car, make sure that turning off the charging sound will not hide a critical warning about the device overheating, which may also be accompanied by an audible signal.
