How to amplify the sound on Xiaomi: from basic settings to hidden chips

Weak sound on Xiaomi devices is a common problem that spoils the experience of watching movies, listening to music or calling. Even flagship models like the Xiaomi 14 Ultra or Redmi Note 13 Pro+ sometimes sin with a quiet speaker due to factory limitations or software features of MIUI. But the good news is that you can fix this without repair – just know the hidden settings and a few proven tricks.

In this article, we will discuss 7 ways to amplify sound, from standard settings to advanced methods using engineering menus and third-party applications. Separately, we will focus on the features of Xiaomi TVs (Mi TV A Pro series, Redmi Smart TV) and Xiaomi Buds headphones. All instructions are relevant for MIUI 14/15 and HyperOS (2026).

1. Basic volume settings in MIUI

Before digging through the engineering menu or installing third-party utilities, check the standard settings. Often the problem lies in the wrong audio profile or system limitations.

Open Settings → Sound and vibration. Here, pay attention to:

• 🔊 Sound mode: Select Dynamic instead of Balanced – this automatically adjusts the volume to the surrounding noise.
• 🎵 Equator: activate the preset "Bases" or "Rock" - they amplify the low frequencies, making the sound volumetric.
• 📱 Separate media adjustment: in some models (e.g, POCO F5) You can split the volume for music and notifications.

If your model has Dolby Atmos (available on Xiaomi 13T, Redmi K60 and later), turn it on in the same menu. This algorithm virtualizes surround sound even through the built-in speakers. For better effect, choose a profile of "Movie" or "Music".

2. Engineering menu: hidden volume settings

For advanced users, the most effective way is to use the engineering menu (#4636## or #36446337##) where you can manually increase the volume of speakers, microphones and even adjust the frequency response.

Instructions for smartphones:

1. Enter the code ##36446337## in the Phone app.
2. Go to the Hardware Testing → Audio tab.
3. Select LoudSpeaker Mode (for the main speaker) or Headset Mode (for headphones).
4. In the Value field, increase the numbers by 5-10 units from the current ones (maximum 160 for the speaker, 120 for headphones).
5. Press Set and restart the device.

Do not exceed the value of 160 for the speaker

Save the original settings (take a picture of the screen)

Check the sound after each change.

Do not change the microphone settings without needing to-->

For Xiaomi TVs, the way is different:

1. Press the Menu + Volume Down buttons on the remote at the same time for 5 seconds.
2. Select Factory Settings → Audio from the menu.
3. Find Speaker Gain (Speaker Amplification) and Bass Boost (Bass Amplification) options.
4. Increase the values by 2-3 dB (no more than 6 dB to avoid distortion).

⚠️ Attention: On the TVs Xiaomi Mi TV Q2 and new changes in Audio parameters DSP This can cause the sound to be reset to factory settings.

3. Sound amplification applications

If standard methods didn't work, try third-party utilities. They work at the system level and can bypass the limitations of MIUI.

To install ViPER4Android on Xiaomi without root:

1. Download APK from the official website (version for Android 12+).
2. Install Magisk Module "ViPER4Android FX" through Magisk Manager.
3. In the application settings, select the Legacy Mode driver.
4. Activate Clear Bass or XBass profiles to amplify low frequencies.

💡

Before installing any sound modifier, backup your MIUI settings through Settings → About Phone → Backup. This will help restore factory sound when crashes.

4. Features of sound amplification on Xiaomi TVs

Xiaomi TVs (especially the budget Redmi Smart TV series) often suffer from quiet sound due to weak built-in speakers (usually 2×8W or 2×10W), a combination of software and hardware solutions will help.

Programmatic methods:

• 🔊 Turn on the settings. → Sound. → Bass amplifier (available on PatchWall 4.0 models)+).
• 🎛️ Activate Dynamic Volume – This automatically increases the volume of silent scenes in movies.
• 📻 In the Advanced Sound Settings menu, select Stadium or Concert Hall mode.

Hardware solutions:

• 🎧 Connect Xiaomi Soundbar via HDMI ARC Optical output – this will increase volume by 40-60%.
• 🔌 Use an external amplifier (e.g. Xiaomi Mi Bluetooth Audio Receiver) to connect speakers.
• 🔄 If the TV supports eARC (Models 2022)+ Connect the sound system through it - this will allow you to transmit uncompressed sound Dolby Digital+.

⚠️ Attention: On the TVs Xiaomi Mi TV P1 and Q1E When connected via Bluetooth, the sound may become quieter due to protocol limitations. A2DP. Use a wired connection or switch to aptX codec in Bluetooth settings.

5. Sound amplification in Xiaomi headphones (Buds, Earbuds)

Xiaomi’s wireless headphones (Buds 4 Pro, Earbuds 3 Pro) have hidden audio settings that can be activated via the Mi Home or Xiaomi Wear app.

Step 1: Connect your headphones to your smartphone and open the Xiaomi Wear app.

Step 2: Go to Devices → [Your Headphones] → Sound settings.

Step 3: Activate:

• 🎶 Immersive Sound Mode – Increases volume by 15-20%.
• 🔄 Adaptive noise cancellation – automatically adjusts volume in noisy places.
• 📊 Customization of the equalizer - manual frequency setting (we recommend lifting sliders by 1-3 kHz for vocals and 60-100 Hz for basses).

For Xiaomi Buds 3T Pro and later, the LDAC feature is available, a high-resolution codec that improves sound detail.

1. Open Bluetooth settings on your smartphone.
2. Click on the gear icon next to the connected headphones.
3. Choose Sound Quality → LDAC (990 kbps).

6.Sound problems after MIUI update

MIUI or HyperOS updates sometimes reset audio settings or introduce new restrictions. If the sound is quieter after the update, try:

Method 1: Resetting the sound settings

1. Go to Settings → Applications → Application Management.
2. Find the audio settings (or AudioFX) and clear the cache.
3. Reset the device.

Method 2: Rejection of Media Codec Update

Some devices (such as the POCO X5 Pro) will not support aptX and LDAC codecs after upgrading to MIUI 15.

1. Install the Developer Options Enabler app from Google Play.
2. Activate Developer Mode (7 times click on the MIUI version in your phone settings).
3. Back to Settings → Additionally. → For developers.
4. Find Turn off the absolute volume of Bluetooth and activate this setting.
5. Reconnect the headphones.

Method 3: Manually Updating Sound Drivers

For Qualcomm Snapdragon devices (e.g. Redmi Note 12 Pro+):

1. Download the latest version of Qualcomm Atheros Driver from Qualcomm.
2. Set it through ADB Team: Adb install -r -d qca_driver.apk
3. Reset the device.

💡

If the speaker is missing after the update, check the settings for Settings → Special features → Sound Improvement. Sometimes the system automatically activates the "Silent Sound" mode to save battery life.

7 Mechanical Methods of Improvement of Sound

If the software methods have failed, pay attention to the physical factors:

For smartphones:

• 🛠️ Clean the speaker grille of dust (use a soft brush or compressed air).
• 🔧 Check the density of the rear cover fitting - on some models (Redmi) 10C) The sound is “muffled” due to improper assembly.
• 📦 If the speaker is damaged, replace it with the original one (article for Xiaomi) 12T — MDY-11-16).

For TVs:

• 🔊 Move the TV from the wall by 10-15 cm – it will improve acoustics.
• 🧲 Use magnetic on-screen speakers (e.g. Xiaomi Mi) TV Soundbar 3.1) for bass enhancement.
• 🔌 Connect the TV to the receiver through HDMI ARC — This will allow the use of external columns.

For headphones:

• 🎧 Check the integrity of the bottles - worn gaskets reduce the volume by 30%.
• 🔋 Replace the battery if the headphones discharge quickly – this affects the power of the amplifier.
• 📡 Update the firmware headphones through Mi Home (relevant to Xiaomi Buds 4 Pro).

⚠️ Note: On Xiaomi smartphones with stereo speakers (such as the Xiaomi 13 Pro), it is not recommended to simultaneously increase the volume through the engineering menu and booster apps.
