The speakers in Xiaomi smartphones are often the subject of criticism: users complain of quiet sound when calling, listening to music or watching videos. The reasons can be different from factory limitations of MIUI to physical wear of components.
In this article, we will discuss 7 In the most tried and tested ways, from basic settings in the phone menu to profound changes in system files (for power users), it's important that not all methods are equally secure. mixer_paths.xml This can cause damage to the speaker if the load is exceeded, so we will specify the risks and alternatives for each option.
If you own a Redmi Note 12, POCO X5 or another MIUI 14/15 model, start with the first three ways β they do not require root rights and are suitable for 90% of devices. Older models (such as the Redmi 4X or Mi A2) may need additional manipulation.
MIUI Sound Settings: What Can Be Changed Without Root
The first thing to check is the standard sound settings in the firmware. Xiaomi hides some options in the depth of the menu, but they take less than a minute to activate.
Open Settings β Sound and vibration and pay attention to:
- π Media volume: slider often gets knocked down after updates.Check its position.
- π΅ equalizer MIUI: Turn on the preset "Bas" or "Rock" - they automatically turn up the volume on the 10-15%.
- π Voice amplification (in the section "Calls"): relevant for a conversational speaker.
- π Do not disturb: make sure that the mode is not manually activated or on schedule.
On some models (e.g. POCO F4 GT), this menu includes optional settings β Improve sound. Turn it on β the system automatically optimizes the volume for the current environment (e.g. in a noisy room).
π‘
If the sound is quieter after the MIUI update, try resetting the sound to factory settings: Settings β Applications β Application Management β Three dots (menu) β Resetting the application settings. This will return the volume sliders to their original state.
2. Enable developer mode and hidden sound options
MIUI has hidden parameters that allow you to increase the volume beyond the standard limits, and to activate them, you need to turn on the developer mode:
- Go to Settings. β The phone.
- Tap 7 times on the MIUI version (you will be notified "You became a developer").
- Go back to the main settings menu and open a new section for developers.
Now look for the options related to sound:
- π Disable absolute volume: This will allow you to independently adjust the volume on your phone and connected devices (earphones, speakers).
- π§ Force the use of stereo speakers: relevant for models with two speakers (for example, Xiaomi 13 Pro).
- πΆ Bluetooth debugging: If volume problem occurs when connecting to a car radio, turn on Enable Bluetooth HFP.
After the changes, restart your phone. If the options don't show up, your model doesn't support them (relevant for budget Redmi on Android Go).
What to do if the developer mode is not turned on?
3. Apps to amplify sound: top-5 utility
If the system settings donβt work, try third-party apps. We tested 15 programs and selected those that actually work on Xiaomi without root:
| Annex | Max, volume up. | Support for MIUI | Cons |
|---|---|---|---|
| Volume Booster | up to +30% | Yes (including MIUI 15) | Advertising, sometimes resets settings |
| Equalizer FX | up to +20 per cent | Yes (requires permission to overlay) | A complex interface for beginners |
| Precise Volume | up to +15 percent | Yes (works with Android 10+) | Paid version for fine tuning |
| Music Volume EQ | +25% | Partially (may conflict with MIUI Music) | Closed in 2023, latest version with bugs |
| Wavelet | up to +40% (with equalizer setting) | Yeah (works better for POCO) | Requires manual calibration for speakers |
We recommend starting with Wavelet, which is an app that uses Google's algorithms to optimize sound.
- Select Preset Loudness in the Equalizer section.
- Activate Auto EQ and select your smartphone model (if itβs on the list).
- Turn on Bass Tuner and set the value of +3 dB.
Make sure that:
β The phone is at least 50% charged (some apps are loading the processor heavily)
β B Settings β Annexes β Special access allowed overlays for booster
β Other sound modifiers are disabled (e.g., built-in equalizer) MIUI)
β You have created a backup (backup) of the sound settings-->
4. Editing mixer_paths.xml: system-level volume increase
This method requires root rights and is only suitable for power users, and allows you to change the volume limits set by the manufacturer by editing the system file. mixer_paths.xml.
β οΈ Note: Incorrect values in this file may cause damage to the speaker or distortion of the sound.We recommend that you first back up the original file.
Instructions:
- Install Root Explorer or FX File Explorer (with root support).
- Cross the path. /vendor/etc/mixer_paths.xml (or /system/etc/mixer_paths.xml old-model).
- Find the lines with the parameters: <path name="speaker"> <ctl name="RX1 Digital Volume" value="84" /> <ctl name="RX2 Digital Volume" value="84" /> Here value="84" is the current volume limit (maximum is usually 96, but for Xiaomi the safe limit is 90).
- Change the value to 90, save the file and reboot the phone.
For dual-speaker models (such as the Xiaomi 12T Pro), you need to edit both speaker and speaker-secondary. After you change, check the sound at different frequencies β if wheezing occurs, return the values back.
π‘
On some firmware (for example, MIUI EU) file mixer_paths.xml It's a change-proof system, and in this case, you're going to have to use Magisk modules like the Audio Modification Library.
5. Hardware causes of silent sound: when software methods do not help
If none of the above methods worked, the problem could be the physical state of the speaker.
- π Grid pollution speaker: dust and pile eventually clog holes, which reduces the volume on the 30-50%. Clean the net with a soft brush or compressed air.
- π§ Moisture: Even after drying, oxidized contacts can make sound worse, and only a replacement speaker can help.
- π Bad contact of the plume: if the sound disappears when pressing the case, the speaker plume has moved away from the motherboard (disassembly is required).
- π Membrane wear: in older models (Redmi) 3S, Mi 5) speaker membrane loses elasticity, resulting in wheezing and quiet sound.
To diagnose a hardware problem:
- Connect headphones - if the sound in them is loud, the problem is in the dynamics.
- Record the sound from your phone with another device and listen at normal volume (wheezing and distortion will be noticeable).
- Try playing the sound through Engineering Mode. To do this, dial ##36446337## and select Hardware Testing β Audio β Speaker Test.
π‘
If you suspect a hardware malfunction but are unsure of the diagnosis, use the speaker test in the Phone Doctor Plus app to show how much your device volume deviates from the model reference values.
6. Alternative methods: from Bluetooth amplifiers to external speakers
If it is not possible to increase the volume programmatically, consider external solutions:
- π§ Bluetooth sound amplifier: devices like FiiO BTR3 or BT-W5 They're going to be on the phone and amplifying the signal before they're going to the headphones/columns. +50%.
- π Portable columns with AUX: Even budget models (such as the Xiaomi Mi Portable Speaker) sound louder than the built-in speaker.
- π± Magnetic holder with amplification of sound: accessories like PopSocket with a resonator direct the sound forward, increasing the volume by 20-30%.
- π USB-C/Type-C Adapter with amplifier: suitable for models without 3.5 mm connector (for example, Xiaomi) 13 Adapters from AudioQuest or iFi Audio give a clean sound without distortion.
For POCO and Black Shark owners, there is another life hack: these models support the connection of game headphones with vibration (for example, Razer Kraken X), complete with software that automatically raises the volume in games and videos.
7. Frequent mistakes and how to avoid them
When trying to turn up the volume, users often make critical errors that lead to the opposite result.
- β Set the maximum volume in mixer_paths.xml (significance >92 This will cause distortion and risk burning the speaker).
- β Using multiple sound boosters at the same time causes conflicts and lowers volume.
- β Clear the cache of sound applications manually (this resets the user's equalizer settings).
- β Update MIUI while editing system files - this will return all volume limits to factory.
Also avoid applications that promise to βvolume up 200%β or that are either dead or contain malicious code. Check reviews on 4PDA or XDA Developers before installing.

If after experimenting with the sound, the speaker began to wheez or stopped working at all, immediately return all settings to the factory and contact the service center. Xiaomi may refuse warranty repair if it finds traces of root access or editing system files.
