How to change the sound of the screen lock on Xiaomi Redmi Note 8 Pro: official and unofficial methods

The screen lock sound on the Xiaomi Redmi Note 8 Pro is a small but important element that accompanies you dozens of times a day. Over time, the standard signal can get bored, especially if it is too loud, quiet or just disliked by its timbre. Fortunately, MIUI offers several ways to change it, from simple settings to install custom tunes through third-party apps.

However, it’s not that simple: depending on the firmware version (MIUI 12, 13 or 14) and regional build (global, European, Chinese), the options available may vary. In this article, we’ll discuss all the working methods for the Redmi Note 8 Pro, including bypassing the limitations of system sounds, installing custom tunes, and even replacing them through ADB for advanced users, and you’ll learn why some sounds may not play after replacement and how to fix it.

If you want to not only change the lock sound, but also adjust the vibration or remove the sound altogether – at the end of the article there is an FAQ with answers to popular questions on this topic.

1. Method: Use of standard MIUI sounds

The easiest and safest method is to select one of the preset sounds in Xiaomi’s settings, which does not require root rights or additional apps, but has a limitation: you can only choose from those tunes that are already in the system.

To change the lock sound through standard settings:

1. Open the Settings app on your Redmi Note 8 Pro.
2. Go to the Sound and Vibration section (in some versions of MIUI it may be called Sound).
3. Select the screen lock sound (or lock sound).
4. Scroll through the list of available sounds and click on your favorite to listen.
5. Confirm the choice by pressing OK or Ready.

Depending on the firmware version, the list can include both standard signals (MIUI, Bamboo, Marimba) and thematic sounds (for example, from theme packages).

⚠️ Note: On Chinese firmware (China) ROM) The section with the lock sounds may be missing or hidden, in which case, try changing the region in the settings to India or Russia (see section 4).

2. Method: installation of sounds through MIUI-themes

MIUI-Themes are the official way to customize Xiaomi’s interface, which allows you to change not only wallpaper and icons, but also system sounds, including a lock signal.This method works on all versions of the Redmi Note 8 Pro, but requires an Internet connection and a Mi Account account.

Instructions for setting sounds through themes:

• 🎵 Open the Themes app (icon with brush).
• 🔍 In the search bar, enter the request for lock sound or lock sound.
• 📥 Choose your favorite theme with sounds and click Download.
• 🔧 After download, click Apply – the sounds are automatically integrated into the system settings.
• 🔄 Back to Settings → Sounds and vibrations → Locking sound to select a new sound.

The advantage of this method is that the themes often contain unique sounds that are not in the standard set, but be careful: some themes can change not only sounds, but also other interface elements (fonts, animations).

3. Method: Replacement of sound through third-party applications

If you don't like standard sounds and themes, you can install custom locking sound through third-party apps, like Zedge, Ringtone Maker, or MIUI Sound Changer (for advanced users), and let's take a look at the process with Zedge:

1. Download and install Zedge from Google Play.
2. Open the app and go to Notification Sounds or Ringtones.
3. Find the right sound (can be filtered by Lock Sounds category).
4. Click on the sound, then select Set as → Lock Sound.
5. Confirm the replacement in the system dialogue.

Important: Not all applications work correctly with MIUI. If the sound hasn't changed, check:

• 🔊 The volume level of notifications (sometimes the sound of the lock is tied to it).
• 📱 Restart your phone – sometimes changes only apply after a reboot.
• 🛠️ Make sure the app has access to Storage and Sound Settings.

⚠️ Note: On some versions MIUI 14 third-party applications may not have access to system sound replacements due to tightened security restrictions. ADB-team (see section 5).

Problem Solving: Why doesn't the sound change?

Sometimes, even after all the manipulations, the locking sound remains the same, and this can be due to several reasons:

If none of these things work, make sure the locking sound is completely off.

1. Go to Settings → Sounds and vibrations.
2. Find the lock sound or system sounds and make sure it is active.

5. Advanced method: Replacement of sound through ADB (for experienced)

If the standard methods don't work, you can manually replace the locking sound through the Android Debug Bridge (ADB), which requires developer mode on and access to the computer, but gives you full control over the system sounds.

Instructions:

1. Turn on Developer Mode: Go to Settings → About Phone. Click 7 times on MIUI Version until you become a developer.

Important: improper use of ADB can cause system failure. Before executing commands, make a backup copy of the data.

💡

If the sound is not played back after being replaced by ADB, check the file path. In some versions of MIUI, system sounds are stored in /system/product/media/audio/ui/ instead of /system/media/audio/ui/.

Alternatives: Turn off the sound or replace it with vibration

If you don't like the sound of the lock, you can turn it off or change it to a vibration.

• 🔇 Go to Settings. → Sounds and vibrations → Lock sound and select No sound.
• 📳 To enable vibration instead of sound, activate the Vibration switch when you lock in the same section.
• 🎚️ Set the vibration intensity in the settings → Sounds. → Vibration.

The Redmi Note 8 Pro also has a hidden adaptive sound feature, which allows the system to automatically adjust the lock volume depending on the surrounding noise.

1. Activate Developer Mode (see Section 5).
2. Go to Settings → Additional → For developers.
3. Find the Adaptive Sounds option and turn it on.

💡

Turning off the lock sound does not affect the notification or alarm sounds – they are set separately.

7. Frequent mistakes and how to avoid them

When replacing the lock sound, users often encounter common errors, and here are the most common ways to solve them:

• 🚫 Error: "Failed to set sound" when selecting from Zedge.Solution: Give the app permission to record in storage (Settings) → Annexes → Zedge → Permits).
• 🔊 Mistake: The sound plays, but breaks through 1 Solution: Shorten the sound file to 2-3 A second in any audio editor (e.g. Audacity).
• 🔄 Error: After the update MIUI Solution: Reapply the theme or sound through ADB — Updates often reset custom settings.

Another common problem is the conflict of sounds when using third-party launchers (for example, Nova Launcher or POCO Launcher).

1. Return to the standard MIUI launcher.
2. Set the lock sound through the system settings.
3. Return to the third-party launcher - the sound should be preserved.
