How to amplify the sound on Xiaomi: from MIUI settings to hardware tricks

Have you ever caught yourself thinking that the sound on your Xiaomi is too quiet? Music can barely be heard on a noisy subway and the person on your phone has to be asked to speak louder? The problem of low sound is familiar to many owners of Redmi, POCO and Mi smartphones β€” especially on budget models where the manufacturer saves on speakers. But don't be quick to blame the iron: in 80% of cases, the volume can be increased programmatically without having to repair.

In this article, we will discuss 7 working ways to amplify sound - from hidden settings MIUI You'll learn how to turn up the volume of speakers, headphones and Bluetooth devices without sacrificing quality. And if your Xiaomi suddenly became quieter after the upgrade, you'll find a solution for that. MIUI 14/15 model 2020–2026 year-end.

Warning: Some methods require unlocking the bootloader or root rights. If you are a beginner, start with safe ways (sections 1-3). For experienced users, the tricks in sections 4-7 will come in handy - but remember: any changes are at your own risk!

1. Enable "Amprovement of Sound" in the MIUI settings

The easiest and safest way is to activate the built-in audio amplification feature in MIUI, which is hidden in the special features menu, but works on all Xiaomi, Redmi and POCO models (except the oldest ones on MIUI 10 and below).

How to turn on:

  1. Open the Settings. β†’ Special facilities.
  2. Go to Hearing (or Sound and Vibration β†’ Sound Amplification on New Versions).
  3. Activate the sound amplification slider.
  4. Set your gain level (we recommend starting at 50% to avoid distortion).

This feature increases the volume of all audio sources: calls, music, video and even system sounds.

  • πŸ”Š It only works with wired headphones and a built-in speaker. Bluetooth doesn't apply.
  • 🎧 There may be background noise on cheap headphones (solved by reducing the gain level).
  • πŸ“± On some models (for example, Redmi Note 10) the function is called audio amplification.

πŸ’‘

If you start wheezing after you turn on the amplification, reduce the level to 30-40%, which will remove the distortion, but will keep the volume up.

2.Tune the equalizer and sound effects

MIUI has an integrated equalizer that many users ignore, and it's a mistake: the right settings can increase volume by 15-20% without loss of quality, especially on bass and medium frequencies.

How to set up:

  1. Open the Music app (standard player from Xiaomi).
  2. During the playback of the track, tap on the icon. βš™οΈ Settings β†’ equalizer.
  3. Choose preset Rock or Pop – they amplify the average frequencies, where the main volume of voice and instruments is concentrated.
  4. For maximum effect, manually lift the sliders to 100 Hz, 250 Hz and 1 kHz (but not higher than +6 dB, otherwise distortion will appear).

If you use third-party players (Spotify, YouTube Music), install Equalizer FX from Google Play, which works systemically and amplifies the sound in all applications:

  • πŸŽ›οΈ Enable Hardware Acceleration in the App Settings.
  • πŸ”Š Choose Bass Boost or Loudness Preset.
  • πŸ“± Xiaomi with Snapdragon works better ViPER4Android (Magisk demands).

3. Clean the speakers of dust and debris

Up to 30% of the volume loss on Xiaomi smartphones is due to clogging of speakers with dust, pile or moisture.This is especially true for models with a lower speaker (e.g. Redmi Note 12, POCO X5), which is often clogged in pockets.

How to clean the speakers:

  • 🧹 Use a soft brush (like makeup) or a toothpick wrapped in cotton. Carefully walk around the speaker grille in circular motions.
  • πŸ’¨ Compressed air (a cleaning tank) will help blow dust out of deep slits. Keep the balloon upright so as not to freeze the speaker.
  • 🎡 To check, play a track with deep bass (for example, 40 Hz) – if the sound became cleaner, the cleaning helped.

⚠️ Warning: Do not use wet wipes or alcohol - they can damage the membrane of the speaker. Also avoid vacuum cleaner: it creates too strong traction and can tear the membrane.

If the sound has not improved after cleaning, the problem may be a hardware malfunction (for example, a broken contact or a damaged membrane), in which case only the service center will help.

4. Install custom software or modified firmware

For advanced users willing to sacrifice the warranty, there is a radical way to do it: a modified sound stack firmware, and some custom firmware, such as Pixel Experience or LineageOS, uses Google drivers that are better optimized for sound than standard Xiaomi.

What custom firmware does:

  • πŸ”Š Increase the maximum volume by 20-40% due to optimized drivers.
  • πŸŽ›οΈ Advanced equalizer settings (e.g, ViPER4Android box).
  • πŸ“± Support LDAC and aptX for Bluetooth headphones (on some Xiaomi models, these codecs are disabled by default).

How to stitch:

  1. Unlock the bootloader via fastboot oem unlock (instructions on the official Xiaomi website).
  2. Install custom recovery (TWRP or OrangeFox).
  3. Download the firmware from the XDA Developers forum (for example, this thread will suit the Redmi Note 11).
  4. Sweat through recovery, having previously made a backup.

⚠️ Warning: Wrong firmware can turn a smartphone into a brick.Before the procedure, check the firmware compatibility with your model (for example, the Redmi Note 10 Pro and Redmi Note 10 Pro Max have different sound chips!).

Which firmware is better for sound?
The best results are shown by firmware based on AOSP (for example, Pixel Experience or Havoc-OS), because they use stock drivers from Google with improved audio processing. For models with Snapdragon 8xx (for example, Xiaomi 12 Pro), crDroid will suit β€” it includes support for Dolby Atmos without root. But firmware based on MIUI (like Xiaomi.eu) give a minimal volume gain, because they use the same sound drivers as the stock version.

5.Use an external sound amplifier (DAC)

If software methods don’t help and the sound in the headphones is still quiet, the problem may be your Xiaomi’s weak digital-to-analog converter (DAC). Budget models (such as the Redmi 9A or POCO M3) come with cheap chips that can’t provide enough power for high-end headphones.

The solution is an external DAC. It's a compact device that connects via USB-C or Lightning that takes over the audio processing. Even low-cost models (like the Xiaomi USB-C to 3.5mm DAC for ~10$) give a noticeable boost in volume and quality.

DAC modelPrice (2026)Suitable forVolume up.
Xiaomi USB-C to 3.5mm DAC~10$Budget headphones (up to 32 ohms)+15–20%
iBasso DC05~50$Headphones 32-150 Ohms+30–40%
AudioQuest DragonFly Cobalt~300$Professional headphones (up to 300 ohms)+50% and higher

How to choose DAC:

  • 🎧 For headphones up to 32 ohms (most liners) will be enough budget Xiaomi DAC.
  • 🎡 For full-size headphones (e.g. Audio-Technica) ATH-M50x) need DAC with an amplifier (e.g. iBasso) DC05).
  • πŸ“± Check the compatibility: some of them DAC demand OTG-adapter.

πŸ’‘

External DAC not only amplifies the sound, but also reduces the load on the smartphone battery, as audio processing takes place in a separate chip.

6. Modify the files mixer_paths.xml (advanced)

This method requires root rights and is designed for users who are not afraid to dig into system files. mixer_paths.xml It contains volume settings for all audio devices (speakers, headphones, microphone) and by changing it, you can increase the maximum volume level to the hardware limit.

Instructions:

  1. Get root access (for example, through Magisk).
  2. Root Explorer or Solid Explorer is a good way to go to /vendor/etc/mixer_paths.xml (or /system/vendor/etc/ on some models).
  3. Make a backup of the file!
  4. Open the file in the text editor and find lines with speaker or headphone.
  5. Increase max by 20 to 30 percent, for example, replace max="80" with max="100."
  6. Save the file and restart the smartphone.

Example of a modified unit for a speaker:

<path name="speaker">


<ctl name="RX1 Digital Volume" value="95" />




<ctl name="RX2 Digital Volume" value="95" />




<ctl name="Speaker Left Volume" value="18" />




<ctl name="Speaker Right Volume" value="18" />




</path>

⚠️ Attention: Inappropriate values can cause the speaker to burn out or distort the sound. Start with a small magnification (5-10%) and test. On models with stereo speakers (for example, Xiaomi). 11T) modify both channels (RX1 and RX2) equally.

Backup the original file | Check the smartphone model (Snapdragon and MediaTek settings are different) | Increase the values gradually (no more than +10% at a time) | Test the sound after each change | Have a stock firmware on hand to roll back-->

7. Check for hardware malfunctions

If none of these things worked, the problem could be hardware, and here are the most common malfunctions that make Xiaomi lose volume:

Symptoms.Probable causeDecision
The sound is only in the headphones, the speaker is silentThe speaker plume has gone away or the connector is damaged.Disassembly and soldering (experience required)
The sound wheezes at maximum volumeDynamic membrane damaged.Replacement of the speaker (cost ~15-30 $)
Volume itself decreases after 5-10 seconds.Protection against overheating of the sound chipCleaning from dust or replacing thermopaste
There's no sound in the bells, but the music is playing.Misfunctioning microphone or audio codecDiagnostics at the service center

How to diagnose the problem:

  1. Connect another headphone – if the sound is normal, the problem is with your headphones.
  2. Test your smartphone on other software (for example, download to Safe Mode or slick custom recovery).
  3. Check if your smartphone is overheating when playing the sound (use the CPU Monitor app).

If the diagnostics show a hardware malfunction, contact the service.

  • πŸ”§ Dynamic replacement: 15-30$.
  • πŸ”§ Rationing plume: 10-20$.
  • πŸ”§ Replacement of audio codec: 40-80$ (Qualcomm models are cheaper than MediaTek).
