How to increase the volume on Xiaomi phone: from standard settings to hidden features

Are you missing out on important conversations because of a quiet speaker or the music in your headphones sounds like a blanket? The problem of weak sound on Xiaomi smartphones (including Redmi, POCO and Mi) is more common than it seems, and the reasons lie not only in hardware limitations, but also in the software settings that the manufacturer hides from the user “concerning” about the security of the device.

In this article, we’ll look at all the ways you can amplify your audio, from basic Android settings to modifying your system files via ADB. You’ll learn how to turn up the volume of your speaker, headphones, and Bluetooth devices without risking damage to your hardware. And for advanced users, you’ll find instructions for working with the engineering menu and Magisk modules.

Important: methods are classified as safe (no root rights required) and potentially risky (with changing system parameters), and we have marked each method with the appropriate mark so that you can choose the best option.

1. Checking basic sound settings

Before you climb the engineering menu or install third-party apps, make sure the problem isn’t with standard settings. Xiaomi often limits the default volume due to European regulations (EU Volume Limit Directive).

Open Settings → Sound and vibration and do the following:

• 🔊 Turn off volume limit: Find "Safe Volume" or "Loudness Limit" and deactivate it. On some models (Redmi Note 12, POCO X5) This parameter is hidden - see the next section.
• 🎧 Set up sound profiles: Switch to Dynamic or Music mode – they often have a higher volume threshold than Conversation".
• 🔄 Reset the sound settings: at the bottom of the Sound and Vibration menu, find Resetting – this will return factory settings if they were accidentally changed.

If the sound remains quiet after this manipulation, move to the next section. On models with MIUI 14+, the volume limit can be blocked at the firmware level, in which case you will need to use ADB (see section 5).

2. Hidden sound settings in MIUI

Xiaomi hides some of the audio settings behind “developers” or special combinations, for example, on Redmi 10 and POCO F4 you can activate the extended volume menu through the engineering menu, but you need to know the correct sequence of actions.

Method 1: Activation of the Engineering Menu

1. Open the Phone app.
2. Enter ##36446337## (for MediaTek) or #4636## (for Qualcomm).
3. Go to the Hardware Testing → Audio section.
4. Select LoudSpeaker Mode and set the Level 5 (maximum) value.

Method 2: Unlocking Restrictions through CIT

• 📱 Install the app CIT (MIUI Hidden Settings).
• 🔓 Allow access to the settings in the menu "Special features".
• 🎛️ Find the "Sound" section and disable the settings EU Volume Limit and Safe Volume Warning.

💡

If the engineering menu doesn't open, try using the MTK Engineering Mode app for MediaTek chips or Qualcomm EngineerMode for Snapdragon. Links to APK can be found on 4PDA.

3. Increase volume through Equalizer and sound effects

The standard equalizer in MIUI not only adjusts the frequencies, but also increases the overall volume by pre-amp, which works for both the built-in speaker and the headphones.

Instructions:

1. Go to Settings → Sound and vibration → Equalizer.
2. Choose a preset of Bass or Rock – they usually have an elevated level of low frequencies, which subjectively increases the volume.
3. Activate the Pre-Amp slider and move it to +3...+6 dB (maximum can cause distortion!).
4. Save the settings as a user profile.

For Bluetooth devices (headphones, speakers) additionally include:

• 🎵 MIUI Sound Enhancer (Improving detail, but can lower volume – turn off if the sound is quieter).
• 🔊 Absolute Volume in the developer settings (disable this setting if the volume "jumps" when adjusting).

4. Third-party applications for sound amplification

If standard methods didn’t work, Google Play apps will come to the rescue, and we tested 15 programs and selected the 3 most effective for Xiaomi:

For installation:

1. Download the application from the table.
2. Allow access to the audio settings in the "Special Features" menu.
3. Turn on the Volume Amplification option and adjust the slider (start at +10% to avoid distortion).

⚠️ Note: Volume Booster-type applications work by software amplifying the signal, which can cause the processor to overheat during long sessions (for example, when listening to music for more than 1 hour). 4-series (Redmi 9A, POCO C31) This causes trottling and a drop in productivity.

Change of system parameters through ADB (without root)

If you’re ready for more radical measures but don’t want root rights, ADB (Android Debug Bridge) will allow you to modify hidden audio settings, a technique that works on all Xiaomi models, including the latest MIUI 15 firmware.

Step-by-step:

1. Activate Developer Mode: Go to Settings → About Phone and click on MIUI Version 7 times.
2. Return to Settings → Additional → For developers and enable “Debugging by USB”.
3. Connect your phone to your PC, install ADB Tools, and execute the commands:

adb shell settings put global volume_steps 30


adb shell settings put global volume_music_steps 30




adb shell settings put global volume_voice_steps 15




adb shell settings put global volume_system_steps 15




adb shell settings put global volume_alarm_steps 15




adb shell settings put global volume_notification_steps 15




adb shell settings put global volume_bluetooth_sco_steps 15

These teams:

• 🔢 Increase the number of volume control steps from the standard 15 to 30, which allows you to more accurately adjust the level.
• 🔊 Unlock hidden intermediate volume values that MIUI conceal.

To apply the changes, restart the device. The effect will be noticeable immediately - the volume slider will become "smoother", and the maximum value will increase by 10-15%.

6. Root methods: modification mixer_paths.xml

Users with unlocked bootloader and Magisk have the most powerful audio amplification tools available.The main file responsible for volume limits — /vendor/etc/mixer_paths.xml. Editing it allows you to remove all software restrictions, but requires caution.

Instructions for Xiaomi with Magisk:

1. Install Magisk and the Audio Modification Library module.
2. Download the Mixplorer editor (with root support) and open the file /vendor/etc/mixer_paths.xml.
3. Find the lines with the parameters: <path name="speaker"> <ctl name="RX1 Digital Volume" value="84" /> <ctl name="RX2 Digital Volume" value="84" /> Replace value="84" with value="92" (maximum for most models).
4. For headphones, change: <path name="headphones"> <ctl name="HPHL Volume" value="16" /> <ctl name="HPHR Volume" value="16" /> at value="22."
5. Save the file, restart the device.

⚠️ Attention: Incorrect values in mixer_paths.xml Can cause: physical damage to the speakers (on Redmi) 8A and similar budget models of the membrane can break at a value above 90), distortion of sound (wheezing at high frequencies), loss of warranty (if the service center detects a modification of system files).

To check the stability after the changes, use the following test:

• 🎵 Enable a track with a wide dynamic range (e.g., a test signal) 20-20000 Hz).
• 🔊 Smoothly raise the volume to maximum - if wheezing appears, reduce the values in the mixer_paths.xml on 2-3 unit.

💡

On stereo models (Xiaomi 12T, POCO F5), edit the settings for both channels (RX1 and RX2) the same way, otherwise the sound will be shifted to one side.

7. Hardware causes of silent sound and their elimination

If the software methods failed, the problem could be physical malfunctions. Typical hardware causes of weak sound on Xiaomi:

For diagnosis:

1. Check the sound in Safe Mode (press the power button → Safe Mode) If the sound has become normal, the third-party app is to blame.
2. Connect Bluetooth headphones – if the sound is loud, the problem is in the speaker or 3.5 mm connector.
3. Record a video with the sound on – if the sound on the recording is normal, and the “live” is quiet, the microphone is to blame (not to be confused with the speaker!).

On Xiaomi with IP53 (like the Redmi Note 11 Pro), speakers are often clogged with dust.

• 🧹 Use a soft brush (not cotton swabs!).
• 💨 Blow the speaker hole with compressed air (a balloon for cleaning equipment).
• 🚫 Do not use wet wipes – this can close contacts.
