Xiaomi smartphone owners often face the problem of quiet sound β whether while watching videos, listening to music or talking on speakerphone. Even flagship models Redmi, POCO or Mi sometimes give out a loud enough sound due to manufacturer restrictions, features of MIUI firmware or hardware limits. But donβt rush to buy an external speaker: in 90% of cases, the volume can be increased software without risk to the speaker.
In this article, we will discuss 7 working methods, from basic MIUI settings to hidden engineering menu features, how to safely raise volume on Xiaomi 11T, Redmi Note 12, POCO X5 and other models without damaging the speaker, and also find out why the sound became quieter after the update and how to fix it. All instructions are tested on current versions of MIUI 14/15 and HyperOS.
1. Check basic sound settings in MIUI
Before digging deeper, make sure the problem isn't the banal settings.MIUI often resets the audio settings after updates or a profile change.
Open the Settings β Sound and vibration and check:
- π Multimedia volume β the slider should be at the maximum (sometimes it gets lost after connecting headphones).
- π΅ Equator β Enable Bass or Rock mode to amplify low frequencies.
- π± Do Not Disturb Mode β Turn it off if it is activated.
- π Adaptive sound β this feature is better to turn off, as it automatically lowers the volume in βquietβ conditions.
Turn off the "Do Not Disturb" mode"|Set maximum volume of multimedia|Select the equalizer profile "Bas" or "Rock"|Deactivate "Adaptive sound"-->
If you have quieted the sound after this manipulation, move on to the next method. On some models (for example, the Redmi Note 10 Pro) in the Sound and Vibration menu β In addition, the Volume Amplification option is hidden - turn it on if you have one.
2.Using System Equalizer and Dolby Atmos
Xiaomi smartphones on Qualcomm chips (such as POCO F4 or Xiaomi 12) support Dolby Atmos technology, which can significantly improve the sound.
- Go to Settings β Sound and vibration β Sound quality.
- Select Dolby Atmos and turn it on.
- In the Profile section, install Movies or Music β they give maximum amplification.
If the Dolby Atmos is missing (relevant for budget models like the Redmi 9A), use the built-in equalizer:
- ποΈ Go to Settings. β Sound and vibration β equalizer.
- π Select the Custom Preset and lift the sliders to 100Hz and 200Hz (this will strengthen the bass).
- π For voice calls, turn on voice amplification in the same menu.
Built-in MIUI|Dolby Atmos|Equalizer app|I don't use it.-->
β οΈ Attention: Excessive low frequency amplification on cheap models (Redmi) 8A, POCO C31) If you hear a distortion, reduce the bass level.
3. Hidden settings of the engineering menu (MTK and Qualcomm)
If standard methods don't work, it's time to look at the engineering menu, which is the service section where you can manually adjust the speaker settings, but be careful: the wrong values can damage the hardware!
Instructions for smartphones on Qualcomm (POCO X3, Xiaomi 11 Lite):
- Open the Phone app and type ##36446337##.
- Go to Hardware Testing β Audio β LoudSpeaker Mode.
- In the Max Vol field, set the value 150 (usually 128).
- Save the settings and restart the phone.
For devices on MediaTek (Redmi 10, POCO M4 Pro):
- Enter the code ##36446337## or #4636###.
- Select Hardware Testing β Audio β Speaker.
- In the Level section, increase the value to 140-160 (not higher!).
What to do if the engineering menu is not opened?
| Xiaomi model | Chipset | Max: Safe value in the engineering menu | Risk of damage to the speaker |
|---|---|---|---|
| Redmi Note 11, POCO X4 Pro | Qualcomm Snapdragon 695 | 150β160 | Low. |
| Xiaomi 12 Pro, POCO F4 GT | Snapdragon 8 Gen 1 | 140β150 | Medium (risk of overheating) |
| Redmi 10, POCO M4 Pro | MediaTek Helio G88 | 130β140 | High (weak dynamics) |
| Xiaomi 13 Ultra | Snapdragon 8 Gen 2 | 128 (factory) | It is not recommended to increase |
β οΈ Warning: If the speaker starts wheezing or the sound gets distorted after a change in the engineering menu, immediately return the factory settings. Prolonged work on inflated parameters can burn the speaker coil, especially on budget models.
4.Apps for amplifying sound (without root)
If you don't want to get into the engineering menu, use third-party utilities that work on top of the system settings and can increase volume by 20-40%.
- π Volume Booster GOODEV β A simple booster with pre-profiles for music, videos and calls. MIUI 14/15.
- π΅ Equalizer FX β powerful equalizer with the function of strengthening bass and high frequencies.
- π± Precise Volume β allows you to fine-tune the volume (useful if the standard steps in the MIUI too rude).
- π Wavelet β uses sound processing algorithms to improve quality and volume (requires Android 10)+).
How to set up Volume Booster GOODEV:
- Download the app from Google Play.
- Launch and give access to the sound settings.
- Turn on Max Volume mode and set the slider to 120-130 percent.
- In the Equalizer section, activate the Bass Boost preset.
π‘
If the sound gets distorted after installing the booster, reduce the gain to 110% and turn off the equalizer in the app. Often the problem is not the volume, but the wrong frequency settings.
β οΈ Note: Some applications (such as Volume Booster from other developers) may conflict with the MIUI Check the reviews for the current firmware version before installing.
5. Update firmware and reset sound settings
Sometimes a quiet sound is a firmware bug, for example, after upgrading to MIUI 15 or HyperOS, many Redmi Note 12 users complained about the volume drop.
- π Resetting sound settings - go to Settings β Annexes β Application management β Three dots (menu) β Reset the application settings. That'll bring back the factory settings. MIUI.
- π± Update firmware - check the relevance of the version in Settings β The phone. β System updates. Sometimes the sound fixes come in patches.
- π§ Retracement to the previous version MIUI β If the problem appeared after the update, you can return the old firmware through Fastboot (instruction below).
How to roll back firmware on Xiaomi:
- Download the desired version of MIUI from the official Xiaomi website.
- Unpack the archive and move the.tgz file to the folder downloaded_rom phone-on.
- Go to Settings β About Phone β System Update β Three Dots β Select a firmware file.
- Confirm the rollback and wait for the reset.
π‘
If the audio is completely gone after the update, check if the Audio Policy settings in the engineering menu are lost. Sometimes the system resets them to zero.
6. Hardware causes of silent sound and their elimination
If the software methods didn't work, the problem could be the hardware.
- π Pollution speaker - dust and pile block the membrane, lowering the volume.
- π§ Moisture intake -- even after drying, the oxidation of the contacts can make the sound worse, and then only repairs can help.
- π Weak battery - with a discharge below 15% MIUI automatically reduces volume to save energy.
- π§ Damage to the plume speaker is a common problem after falls (for example, the Redmi Note 9 Pro plume departs from the motherboard).
How to check for hardware malfunction:
- Connect headphones - if the sound in them is loud, the problem is in the dynamics.
- Call your phone from another device β if the interlocutor does not hear you well, the microphone or communication module is defective.
- Record the voice memo with a built-in voice recorder β if the recording is quiet, the microphone is to blame.
If the diagnosis showed a hardware breakdown, contact the service center.Self-disassembly of Xiaomi smartphones often leads to a loss of warranty due to seals on screws and plumes.
7. Radical methods: root, custom firmware and speaker replacement
If all the previous methods have failed, radical measures remain: they require technical skills and can void the warranty, but they have maximum effect.
- π Getting root rights β allows you to edit system files, for example, mixer_paths.xml, It's a volume limit:
- π± Custom firmware installation β some builds (e.g. Pixel Experience or LineageOS) have less stringent volume limits.
- π§ Replacement of the speaker β Xiaomi it costs 1,500β3,000 β½ depending on the model. POCO You can find original parts on AliExpress.
Example of editing mixer_paths.xml louden:
<path name="speaker">
<ctl name="RX1 Digital Volume" value="84" />
<ctl name="RX2 Digital Volume" value="84" />
</path>β οΈ Warning: Incorrect editing of system files can lead to bootloop ( looped reboot). TWRP.
