How to increase volume on Xiaomi: from settings to engineering menu

Quiet sound on Xiaomi is a common problem that prevents you from listening to music, watching videos, or hearing notifications comfortably. The reasons can range from trivial settings to hardware limitations. In this article, we will examine all the working ways to increase volume, from standard MIUI parameters to hidden functions of the engineering menu and third-party utilities.

It's important to understand that not all methods are equally safe. For example, software amplification through build.prop or engineering menus can cause sound distortion or even damage to speakers when used at maximum volume for long periods of time. We'll note the risks in each section so you can choose the best option.

This article is relevant for all modern Xiaomi, Redmi and POCO devices based on MIUI 12-14 and HyperOS, including Xiaomi 13/14 series, Redmi Note 12/13, POCO F5/X5 and others. If your model is older than 2018, some methods (for example, through ADB) may not work due to outdated firmware.

1. Standard volume settings in MIUI

Before you resort to radical methods, check the basic parameters. There are several places in MIUI and HyperOS where volume is adjusted - and not all users are aware of them.

Open the notification bar and tap the volume icon (or hold it down for a quick jump into settings). Here you will see sliders for:

• 🔊 Media - music, video, games;
• 📞 Calls - volume of conversation;
• 🔔 Notifications — message signals;
• 🔔 Alarm clock - separate adjustment.

If the sliders are already at their maximum, but the sound is still quiet, go to Settings → Sound and vibration → Additional settings. Here is the option to "Raise the volume of the speaker" (not available on all models), Activate it - this will increase the volume by 10-15% without risk to the equipment.

⚠️ Note: On some devices (Redmi) 9A, POCO M3) The option "Rise up speaker volume" may be missing due to weak speakers.

2. Equalizer and sound effects setup

MIUI has a built-in system equalizer that allows you not only to adjust the frequencies, but also to increase the overall volume by amplifying certain ranges.

Settings → Sound and vibration → Sound quality → Equalizer

Choose a preset called Bass or Rock, which automatically raises the low and medium frequencies, which subjectively makes the sound louder. To fine tune it, select User and raise the sliders 100 Hz, 500 Hz and 1 kHz into 2-3 divisions.

Also, turn on the option "Audio Effects Mi" (if available) - it adds a virtual environment, which improves the perception of volume. On models with stereo speakers (Xiaomi 13 Pro, POCO F4 GT), the effect will be more noticeable.

💡

If the equalizer doesn't save the settings after the reboot, reset it to factory settings and reconfigure it. This is a bug in some versions of MIUI.

3. Engineering menu: hidden volume settings

The engineering menu (#36446337##) allows you to change the parameters of the speakers at the hardware level. This method is risky - incorrect values can lead to distortion of the sound or overheating of the speaker, but gives you maximum volume gain.

Instructions:

1. Open the Phone app and enter the code ##36446337## (or #4636## → Phone Information → Test Selection).
2. Go to Hardware Testing → Audio → LoudSpeaker Mode.
3. In the Value field for Max Vol or Volume, increase the value by 5-10 units (usually a maximum of 160).
4. Press Set and restart the device.

On dual-speaker models (Xiaomi 12T, Redmi K50) change the values separately for Speaker and Speaker2 – increasing only one can create an imbalance.

⚠️ Warning: If you have a wheezing or crackling after a change, immediately return the values to the original.

4.Applicants for sound amplification

If system methods don't work, use third-party utilities that work like surface amplifiers, but can add background noise or distortion.

Top.-3 tested applications:

• 🎧 Volume Booster GOODEV — It's a simple booster with pre-presets, suitable for music and video.
• 🔊 Precise Volume – allows you to finely adjust the volume outside the system limits.
• 🎛️ Wavelet - advanced equalizer with support Viper4Android (Magisk requires full functionality).

Install any of them through Google Play and follow the instructions, for example, in Volume Booster GOODEV:

1. Launch the application and give access to the sound settings.
2. Move the Boost Media Volume slider by 10-20%.
3. Activate the “Prevent Distortion” option to reduce distortion.

For root users, the best option is Viper4Android, which allows you to change the parameters of the sound processor at the kernel level, but requires installation through Magisk and manually configuring profiles.

Install Magisk|Download the module Viper4Android|Reset the device|Configure the driver in the application|Pick a preset "Clear Bass"-->

5. Change the build.prop file (for advanced)

The build.prop file contains system parameters, including volume limits, and editing it requires root rights and can cause unstable device performance, but it has the most noticeable effect.

Instructions:

1. Install a file manager with root support (such as Root Explorer or Solid Explorer).
2. Go to /system/build.prop and back up the file.
3. Open the edit file and add at the end of the line: ro.audio.loudness.enable=true persist.audio.fluence.speaker=true persist.audio.fluence.voicecall=true persist.audio.fluence.voicerec=false
4. Save the changes, restart the device.

After application, the loudspeaker will increase by 20-30%, but background noise may appear when playing quiet tracks. To return everything back, delete the added lines or restore the backup.

⚠️ Warning: Incorrect editing build.prop can cause bootloop.If the phone doesn't turn on after the changes, reflash it through Fastboot.

6. Hardware causes of silent sound

If the software methods didn't work, the problem could be physical damage to the speakers or contamination of the connectors.

To check the speakers, use a test call or playback through the Engineering Menu → Audio → Normal Mode. If one of the speakers is not working, you will most likely need to replace it.

On waterproof models (Xiaomi 13 Ultra, Redmi Note 12 Pro+), a quiet sound may appear after moisture is injected.

• 💧 Dry the device in rice or silica gel for 24-48 hours.
• 🔊 Check the sound after drying out completely.
• 🔧 If the problem remains - contact the service (water protection may be violated).

💡

Before disassembling the device for cleaning speakers, turn off the battery (if possible) - a short circuit can disable the motherboard.

7.Alternative solutions: Bluetooth headphones and external speakers

If you can not increase the volume of the built-in speakers, consider connecting external devices:

• 🎧 Bluetooth headphones – even budget models (Redmi Buds 3, Xiaomi AirDots) sound louder than built-in speakers.
• 🔊 Portable speakers – connect via Bluetooth or 3.5 mm (if there is a connector).
• 📱 USB-C/Lightning Dynamics – for models without audio connector (Xiaomi) 12 Lite, POCO F5).

For Bluetooth connection:

1. Activate Bluetooth in the notification panel.
2. Put the headphones/column into pairing mode (usually holding the power button).
3. In the list of available devices, select yours and confirm the connection.

If you use a 3.5mm connector, check it for contamination — often a quiet sound in headphones is associated with oxidation of the contacts. Clean the connector with a cotton swab dipped in alcohol.
