How to Make Sound Louder on Xiaomi Phone: From Standard Settings to Hidden Features

Are you missing important details in a conversation because of a quiet sound or the music in your headphones sounds like a whisper?The problem of low volume on Xiaomi smartphones (including Redmi, POCO and Black Shark) is more common than it seems, and the reasons are not only hardware limitations, but also software settings that the manufacturer deliberately understates for the safety of speakers.

In this article, we'll look at all the ways you can increase volume, from basic MIUI settings to hidden engineering menus and third-party utilities. Importantly, some methods require root rights or can shorten the life of speakers when used uncontrolled, and we'll outline the risks in advance so you can choose the best option without harming the device.

This material is relevant for all current versions of MIUI (including MIUI 14/15 based on Android 13/14) and smartphone models released after 2018. If your device is older, check the compatibility of methods in the relevant sections.

1. Standard volume settings in MIUI

Before you resort to radical measures, check the basic parameters of the system. Xiaomi has several levels of sound adjustment that many users miss:

• 🔊 Separate adjustment: in MIUI The volume of the bell, the media and the alarm are set separately. Press the physical volume button and tap the gear. ⚙️, to open the extended settings.
• 🎧 Reinforcement for headphones: in the menu Settings → Sound and vibration → Sound quality in headphones turn on the option MI Sound Enhancer (not available on all models).
• 📢 Speak mode: during the call, click on the speaker icon in the call interface to redirect the sound to the main speaker.

Pay special attention to Safe Volume in the audio settings. By default, MIUI limits the maximum volume to 75-80% of the physical limit of the speakers. Turn off this option if you are willing to risk sound quality for the sake of volume.

⚠️ Attention: Long-term listening to sound at a higher level 85 dB can cause irreversible hearing loss: European regulations (EN 50332-2) Recommend limiting noise exposure above 80 db 40 weekly.

2. Engineering menu: hidden volume settings

Xiaomi smartphones have an engineering menu where you can manually increase the volume of the microphone, speaker and headphones. This method does not require root rights, but changing the parameters can lead to distortion of the sound.

To open the menu:

1. Enter the phone combination in the app: ##36446337##
2. Choose Hardware Testing → Audio.
3. In Type, specify Media (for media), Ring (for calls) or Sip (for VoIP calls).
4. Set the Max Vol (maximum volume) and Current Vol (current volume).

Recommended values for increasing volume without critical distortion:

⚠️ Note: Exceeding the value of Max Vol = 100 for the speaker can cause physical damage to the membrane. 9A, POCO M3) Risk is higher due to lack of stereo balance.

3. applications for amplification of sound (without root)

If standard methods don’t work well, use third-party utilities. We tested 10 apps from Google Play and selected the three most effective for Xiaomi:

• 🎛️ Volume Booster GOODEV: louden 20-30% It's software-based audio processing, supports customized headphone profiles and a speaker, minus: it can cause delays in games.
• 🔊 Precise Volume: allows you to adjust the volume in 1% increments (instead of the standard 15 levels in the volume). MIUI). Useful for precise adjustment to specific headphones.
• 🎧 Equalizer & Bass Booster: In addition to increasing volume, it offers a 10-band equalizer. On models with Qualcomm Snapdragon runs more stable than on Mediatek.

For installation:

1. Download the app from Google Play.
2. Launch and give access to the sound settings.
3. In the app menu, select Boost Volume or a similar item.
4. Adjust the slider by testing the sound at safe levels.

On Xiaomi models with a Mediatek processor (for example, Redmi Note 11, POCO M4 Pro) sound amplification applications may conflict with system DSP-If you have wheezing after installation, reset the equalizer settings to the MIUI default.

💡

Before using volume boosters, check the Dolby Atmos settings in MIUI (if available).Sometimes turning off this effect automatically increases the volume by 10-15%.

4. Root methods: modifying system files

If you're ready for radical measures and you have root access, you can change the system volume limits, which is a maximum boost, but you need to be careful.

Instructions for experienced users:

1. Install a file manager with root access (such as Root Explorer).
2. Cross the path. /system/etc/mixer_paths.xml (for Qualcomm; or /vendor/etc/mixer_paths.xml (Mediatek).
3. Find the lines with the parameters: <path name="speaker"> <ctl name="RX1 Digital Volume" value="84" /> and increase the value to 90-95.
4. Save the file and restart the device.

To automate the process, you can use the Magisk Module script "Volume Boost," which changes the constraints without manually editing files. Install it through Magisk Manager and select the amplification profile.

⚠️ Attention: On models with IR-with a blaster (e.g. Xiaomi Mi) 10, Redmi Note 9 Pro) modification mixer_paths.xml This can cause the remote to malfunction.Before editing, backup the original file.

5. Hardware causes of silent sound

If software methods do not help, the problem may lie in physical malfunctions:

• 🔇 Pollution speaker: dust and pile block the membrane. Clean the speaker hole with a soft brush or compressed air (a canister for cleaning the technique).
• 🔌 Poor contact headphone jack: on models with a 3.5 mm connector (Redmi 9, POCO X3) oxidation of contacts reduces volume. Use alcohol to clean.
• 🔋 Weak battery: If it's below 15%, the system automatically lowers the volume to save energy. Replace the battery if it's below 70% of its value.
• 🔊 Membrane damage speaker: if the sound wheezes or is absent at high frequencies, a speaker replacement is required — 1 200-2 500 ₽.

To diagnose hardware problems:

1. Connect headphones – if the sound is loud, the problem is the phone’s dynamics.
2. Record your voice on a tape recorder and listen to the tape. If your voice sounds quiet, the microphone is faulty.
3. Check the sound in Safe Mode (press the power button → Safe Mode). If the sound gets louder, it's third-party software.

💡

On Xiaomi waterproof models (IP53 and above), a quiet sound can be caused by moisture entering the speaker. To dry, use the Emergency Water Removal function in MIUI (available in Settings → Memory → Cleanup).

6. Sound optimization for specific scenarios

Loudness is perceived differently depending on the situation, and here's how to adjust the sound to specific tasks:

For owners of Xiaomi with AMOLED-screens (e.g. Mi 11, Redmi) K50) It's useful to know that the speaker in these models is asymmetrical, and when you listen to music in landscape orientation, the sound will be louder if the top of the phone is pointed to the left.

7. Alternative solutions: from headphones to firmware

If no settings help, consider alternatives:

• 🎧 Bluetooth headphones: even the budget Xiaomi Mi Basic 2 will give a cleaner and louder sound than the built-in speaker. For maximum volume, choose models with support for the aptX codec HD.
• 🔊 External speaker: portable speakers Xiaomi Mi Portable Speaker (16 W) connect to Bluetooth and last up to 20 hours.
• 📱 Brush firmware: firmware based on LineageOS or Pixel Experience have no restrictions MIUI Minus: loss of function, like IR-Blaster or Always-on Display.
• 🔧 Replacement speaker: on AliExpress original speakers for Xiaomi are 300-800 ₽. Replacement takes 15 minutes with tools available.

For users who often listen to music through the speaker, we recommend buying the Xiaomi Mi Pocket Speaker 2. Despite its compact size (65 mm), it delivers sound volumes up to 85 dB – 2-3 times louder than the built-in speaker of the smartphone.
