Owners of Xiaomi, Redmi and Poco smartphones often face a situation where a loud beep when starting a screen or voice recorder recording becomes a serious irritant. This is especially true when you need to record a quiet conversation, lecture or video from the screen in a public place where extraneous sounds are unacceptable. Standard settings of the MIUI system or the new HyperOS do not always provide an obvious switch for this feature, forcing users to look for workarounds.
The problem is that in different countries, manufacturers are required to notify everyone in a conversation about the start of recording audio, which is why on global firmware, sound is often sewn deep into the system and not displayed in the usual settings menu, but there are proven methods to circumvent this restriction without obtaining superuser rights.
In this article, we’ll look at all the current ways to turn off sound, from simple volume manipulations to ADB debugging commands. You’ll learn how the MIUI shell alert mechanism works and why it can come back after a reboot. Understanding these processes will help you manage your device’s audio profiles effectively.
Causes of sound and system limitations
The main reason Xiaomi enforces the audio signal when recording is triggered is because of regional data protection laws, which make recording a conversation without notifying the other party illegal in many countries, so manufacturers are embedding this mechanism at the core level, not just a software feature, but a legal requirement that is difficult to circumvent by standard means.
Users often confuse this system sound with regular app notifications. However, unlike instant messenger messages, the start sound is higher priority and can ignore the "Do Not Disturb" mode, this is done specifically to ensure that the alert is heard even if the phone is in silent mode.
⚠️ Warning: Disabling system audio completely may violate the terms of use of the service in your area, and use this option only for personal use and within the framework of applicable law.
It is worth noting that on different versions of MIUI and HyperOS firmware, the behavior of the system may differ; in some builds for the Chinese market (CN), such restrictions may not be initially absent, while the global versions (Global) and the versions for Russia (RU) strictly follow them.
Basic methods: silence and volume
The easiest, but not always effective, way to do this is to control the physical volume. Before you press the record button, try to keep the volume of media or system sounds to a minimum. In some versions of the MIUI shell, the sound of the recording start is tied to the System Sounds channel, rather than the general volume.
The alternative is to use a No Sound or Vibration profile, but as mentioned earlier, system recording alerts often ignore these settings. However, in older versions of Android and MIUI (before version 12), this method worked flawlessly. If you have a previous-generation device, it's worth trying to switch the volume slider completely down.
There's also a nuance to the headset connection, and if you use wired headphones, the sound of the start of the recording can only be played in them, and it's a great lifehack for fast recording without attracting attention. In the case of Bluetooth headphones, delaying the signal can cause the sound to still have time to duplicate through the speaker of the smartphone.
- 🔇 Make sure the system volume slider is lowered to zero before starting the function.
- 🎧 Use a wired headset to isolate the sound of the recording start.
- 📵 On-plane mode sometimes helps disable network checks that affect sound profiles.
Settings of the built-in voice recorder and screen
If you're interested in screen recording, the standard Screenshots or Screen Recording app often has hidden settings. Go to the app via the Tools menu, click three dots in the corner and select Settings. There may be a "Write Sound" option, which is activated by default, and it solves the problem 80% of the time on current firmware.
The situation is more complicated for a voice recorder. Xiaomi's Dictaphone app often doesn't have an explicit switch. However, if you use a third-party call recording app or a voice recorder from Google Play, you may not have access to the system microphone in the background due to the limitations of Android 10 and higher. The built-in app has system privileges, so the start sound there is a must unless other methods are used.
☑️ Checking the recording settings
It's important to distinguish between the sound of the recording start and the sound of the ending. Often users turn off one, forgetting about the other. In MIUI settings, these parameters can be placed in different tabs, and it's also worth checking if voice acting is enabled in special features, which can duplicate system events with voice.
⚠️ Warning: After the HyperOS system update, some settings may reset to factory values. Always recheck the sound configuration after a major update.
Use of USB debugging and ADB commands
For advanced users who have not been helped by standard methods, there is a way to ADB (Android Debug Bridge. This method allows you to change hidden system settings that are not displayed in the GUI. You need a computer, USB-cable and installed drivers ADB.
First, activate the developer mode. To do this, go to Settings → About Phone and quickly click on the MIUI build number seven times. Then, in the advanced settings, turn on "Debugging on USB." Connect the phone to your PC and enter the following command in the command line to check the connection:
adb devicesIf you've got a device, you can try changing the setting for the interface sounds. The specific command depends on the Android version, but often changes the global setting of the sounds:
adb shell settings put global sound_effects_enabled 0This command disables all system sounds on the interface, including keyboard clicks and, in some cases, recording start sound. However, this is a radical solution that will make the phone completely silent in terms of tactile return. Be careful when using ADB commands, as incorrectly changing the system registry can lead to unstable operation.
What if the ADB can’t see the phone?
Comparison of methods of switching off sound
To make it easier for you to choose the right way, we have systematized methods by efficiency and complexity. Some require root rights, others run on stock firmware, and the choice depends on your technical background and the version of Android.
| Method | Efficiency | Difficulty | Risks. |
|---|---|---|---|
| Volume slider | Low (depending on version) | Minimum | Absent. |
| Application settings | Medium | Low. | Absent. |
| ADB teams | Tall. | Tall. | Medium (entry error) |
| Third-party annexes | Variable | Medium | High (access to data) |
As you can see from the table, using the app’s settings is the safest way to go, but if you want a guaranteed result and you’re willing to take the time to set up, ADB is the only viable option for deep system changes without flashing.
💡
The most stable result is a combination of turning off the sound in the application settings and using a wired headset to isolate the residual signals.
Problems with access rights and permits
A common cause of non-disabled sound is application permissions. If you use a third-party voice recorder or screen recording software, make sure it has all the necessary rights. Go to Settings → Applications → All Apps, find the right application, and select Permissions.
Special attention should be paid to the resolution of "Recording sound" and "Above other windows." In MIUI there is also a separate "Out-start" item that needs to be activated to ensure stable operation of the background recording, without which the system can forcibly interrupt the recording or turn on the audible signals as a warning about the operation in the background.
Sometimes resetting permissions for a particular application helps, delete the application data (without deleting the application itself) and reconfigure it. When you first start, the system will ask permissions to access the microphone, sometimes a repeated request changes the priority of the audio profile.
- 📂 Check the permissions in the section "Privacy protection".
- 🔄 Reset the application data if the settings are lost after the update.
- 🛡️ Turn off Optimization. MIUI" In the Developer Menu (requires unlocking).
Alternative solutions and third-party software
If Xiaomi’s built-in tools don’t work, you can turn to alternatives from Google Play. There are many applications for recording calls and screens, such as Call Recorder or XRecorder. They have their own recording engines and can bypass system limitations, although they do not always guarantee high audio quality due to Android locks.
Some users install modified versions of system applications (such as MIUI Dialer with patches) that are free of regional restrictions, but installing such applications requires unlocking the bootloader and carries security risks.
As a temporary solution, you can use the Translation feature on a PC or other smartphone. By recording a screen on a connected device, you get clean sound without the system signals of the Xiaomi phone itself. This requires a second device, but ensures that there are no unnecessary sounds.
💡
To record an important conversation without sound, use a second smartphone with the recorder on, placing it next to the speaker of the first one. This is an old but reliable analog method.
