How to turn off the sound when you turn on your Xiaomi phone

Many owners of Xiaomi, Redmi and POCO smartphones encounter an intrusive sound signal that plays out immediately after the operating system starts.This sound often takes you by surprise, especially if you turn on the device at night or in quiet environments where silence is important. Standard media volume settings do not always help, since the system audio boot is adjusted separately.

In this article, we will discuss in detail all the available ways to remove this signal, learn how to control system sounds through the standard menu, how to use modes of operation and what hidden methods exist for advanced users. Understanding the logic of MIUI and HyperOS will allow you to fully control the acoustic behavior of your gadget.

We will also look at the nuances associated with different firmware versions, since the interface and item names may vary slightly depending on the year of release of the model and the region, it is important to approach the setup comprehensively to avoid situations where sound returns after restarting or updating applications.

Standard settings of system sounds

The easiest and safest way to turn off the sound when you turn on is to use the built-in audio profile settings, with MIUI and HyperOS shells having a separate switch, which is often hidden in the sub-menus of additional settings, and you don't need third-party software or root rights to do this.

First, you need to go to the main settings menu of your device, find the section that handles the audio interface, the path can look like Settings → Sound and vibration, and all the volume sliders and tone switches are concentrated here.

Then you should pay attention to the item "Additional settings" or "System sounds." This is where the switch is located. If you want to completely eliminate any audio notifications from the operating system itself, including keyboard clicks and lock sounds, it makes sense to turn them all off at once.

• 🔊 Open the section “Sound and vibration” in the settings.
• 🔍 Find the "Additional Settings" subsection (may be called "More»).
• 🚫 Remove the tick from the item "Sound when turned on».
• ✅ Check the result by rebooting the device.

⚠️ Note: Some global firmware versions (Global) ROM) This item may be hidden or absent, in which case the system is forced to play sound at start, and the use of alternative methods described below will be required.

After making changes, the system may require confirmation of action. Don't ignore warnings if they appear, as they confirm a change in system parameters. If the switch is active but the sound is still heard, it may be related to the alarm profile or the Do Not Disturb mode, which we'll talk about later.

Use of modes of operation and profile "Without sound"

An alternative and often more effective method is to use job profiles. Xiaomi smartphones allow you to create or activate modes that block all audio notifications, including system ones. This is especially convenient if you need to quickly silence your phone before a meeting or at night.

No Sound or Do Not Disturb (DND) mode takes precedence over standard playback settings. When this mode is active, the phone ignores most triggers for speakers. However, it's important to set exceptions correctly so you don't miss an important call if necessary.

To activate this method, use a sidebar (curtain) or physical volume buttons. Press the volume button until the icon of the crossed-out speaker or moon appears on the screen, signaling the transition to quiet mode.

There is a nuance: in some versions of Android, the system audio download is classified as “Alarm” (Alarm) or “System”, which can ignore the DND mode.

• 🌙 Activate Do Not Disturb Mode through the Notification Curtain.
• 🔇 Make sure the media sound slider is also down to zero.
• ⚙️ Check your schedule settings to automatically turn on quiet mode at night.

Using a schedule is a great strategy. You can set your phone up to automatically go silent from 23:00 to 7:00, in which case, even if you decide to turn it on or restart in the middle of the night, it won't make a sound.

Configure through the Engineering Menu (CIT)

For more experienced users who haven't found a standard switch, there's access to a deep system menu, often called the Engineering or CIT (Customer Information Test), where you can manage low-level parameters of the audio subsystem.

Sign in to this menu is via a special code in the Phone app. Dial the combination ##6484## or ##4636##. The interface may vary depending on the Redmi Note or Mi model. Be careful: changing unknown parameters can lead to unstable work.

In the CIT menu, you need to find the Audio section, which may include the option to turn off system sound or a specific boot sound, and if you find a switch, it will remain deactivated even after you restart.

⚠️ Attention: Engineering menus are for diagnostics.Advertent change of modem settings or screen calibration may require resetting to factory settings.Act only in Audio.

If there is no direct shutdown option, you can try resetting your audio profile to a default one, which sometimes removes custom or erroneous audio settings that the carrier has implemented, but this method is less predictable than using standard switches.

Comparison of methods of switching off sound

To make it easier for you to choose the right option, we have prepared a comparison table that will help you assess the risks and effectiveness of each method for your specific situation and smartphone model.

As you can see from the table, standard settings are the safest way. The engineering menu gives you more control, but it requires caution. The "no sound" mode is a temporary solution, not a permanent shutdown of the function.

The method you choose also depends on how often you reboot your device, and if it's rare, it's easier to put your phone on silent mode before turning it off, and if you change your system settings a lot, you'd better dig into the menu once.

Hidden opportunities and third-party solutions

In situations where the usual means to remove the sound, users turn to third-party solutions. There are automating applications such as Tasker or MacroDroid that can change the settings of the sound under certain conditions.

The method is to create a macro: “If a device boots → set a sound profile “Without sound”.” However, due to Android security constraints, applications often require root rights to change system settings at boot time.

Another option is to use modules for Magisk if the device has root rights, and modules like Silent Boot can directly edit the system files that play the audio file, effectively removing it from the playback chain.

• 📲 Install an automation application (e.g. MacroDroid).
• 🤖 Create a trigger “Device boot is complete».
• 🔇 Add the action "Set the volume of the system to 0».
• 💾 Save the macro and provide the necessary permissions.

It is worth noting that the use of third-party software always carries potential security and stability risks, and before installing such applications, carefully review reviews and permissions requested.

Frequent problems and their solution

Even after the sound is turned off, users may experience situations where the phone still emits signals, often because the sound is not coming from a system event, but from an alarm or notification that goes off immediately after you connect to the network.

Check your alarm settings. If you have an alarm clock set for a time close to the time you turn on, it may go off right away. Also, look for reminder apps and calendars that have their own sound profiles, independent of the system.

Another common problem is connecting a Bluetooth headset or speakers, so if you have a paired device nearby when you turn on your phone, the sound can be played through it, even if the phone itself is in silent mode. Turn off Bluetooth before you start for a check.

⚠️ Note: On some models with dynamic screen refresh rate and improved sound (Hi-Res Audio), the drivers of the sound chip can be initialized with a characteristic click that cannot be software-disabled.

If nothing works, the last resort is a full Hard Reset, which will return the phone to factory status, where it can be turned off by default or turned off by standard means without setting conflicts.
