How to increase the volume on the Xiaomi phone: from standard settings to hidden chips

Have you ever encountered a situation where at maximum volume Xiaomi still can not hear the interlocutor in the handset or music in the headphones? This is a common problem, especially on the budget models of Redmi and POCO, where the manufacturer artificially limits the sound level. But the good news is that there are at least 10 ways to increase the volume, from basic settings to advanced tweaks through the engineering menu.

In this article, we will discuss all possible methods, from official (no risk to warranty) to alternative (require root rights or technical skills), you will learn how to raise the volume of speakers, headphones and Bluetooth devices, and what to do if suddenly the sound became quieter after the MIUI update. Importantly, some methods can lead to distortion of the sound or overheating of speakers, we will warn about the risks in each section.

1. Standard volume settings in MIUI

Before digging deeper, check the basic parameters. MIUI has hidden regulators that many users miss:

  • πŸ”Š Separate adjustment: in Xiaomi, the volume of the call, multimedia and alarm clock is set separately. β†’ Put it on the gear next to the slider. β†’ Choose a profile.
  • 🎧 Reinforcement for headphones: connect wired headphones β†’ Go to Settings. β†’ Sound. β†’ Sound quality in headphones β†’ Activate the sound amplifier (not available on all models).
  • πŸ“ž Loud communication in the handset: during the call, tap on the speaker icon to switch to an external speaker (works even without a headset).

On the Xiaomi 12/13 series and POCO F4/F5, Dolby Atmos mode has been added β€” it can be turned on in Settings β†’ Sound β†’ Sound Effects. This mode does not increase volume directly, but improves clarity at high levels, which subjectively makes the sound β€œlouder”.

⚠️ Note: Some devices (e.g. Redmi Note 10 Pro) may lose bass when Dolby Atmos is activated.

2. Engineering menu: hidden volume regulators

The MTK Engineering Mode (or Qualcomm Service Menu) allows you to manually increase the volume levels for each channel: speaker, microphone, headphones and Bluetooth. This method works on all Xiaomi smartphones, but requires caution.

Instructions for Qualcomm processors (most modern Xiaomi):

  1. Open the phone app and enter the combination: ##4636##
  2. Select Hardware Testing β†’ Audio β†’ Volume.
  3. In the Type list, select Media – Ring multimedia volume – Sph call volume – microphone volume

3. applications for amplification of sound (without root)

If the engineering menu seems complicated, you can use third-party utilities that work on top of the system settings and amplify the sound software.

  • πŸ”Š Volume Booster GOODEV (Play Market: Increases volume on the 20-30% It supports individual profiles for speakers and headphones. 5% battery charge per hour.
  • πŸŽ›οΈ Equalizer FX: built-in MIUI Equalizer, but with advanced settings. Activate Loudness preset to amplify low and high frequencies.
  • 🎧 ViPER4Android (Magisk: the most powerful tool, but you need root rights. Allows you to adjust Limiter and Compressor to increase volume without distortion.

How to install Volume Booster GOODEV:

  1. Download the app from the Play Market.
  2. Open and allow permissions to change the sound.
  3. Move the Media Volume slider 120-130% (maximum - wheezing risk).
  4. Activate the Boost for Speaker option (only for external speakers).

For ViPER4Android, you will need:

  1. Install Magisk and ViPER4Android FX module.
  2. In the application settings, select the Legacy Mode driver.
  3. Enable Master Limiter and set Max Gain to +6 dB.

πŸ’‘

If the sound becomes hoarse after installing the booster, reduce the gain to 110% and turn off the "Bas Boost" option in the application settings.

4. Update MIUI and reset sound settings

Sometimes the quiet sound problem occurs after the MIUI update, so the manufacturer can reset the user settings or introduce new restrictions.

  • πŸ”„ Reset the sound settings: go to Settings β†’ System system β†’ Resetting settings β†’ Reset the sound settings. That'll bring back the factory volume levels.
  • πŸ“₯ Reverse the update: If a quiet sound appears after the update, check the reviews on the forums (for example, 4PDA). Maybe it’s a bug of a particular version. MIUI.
  • πŸ”Š Insert "Adaptive sound": in Settings β†’ Special facilities β†’ Adaptive sound activate the option. The system will automatically adjust the volume to the surrounding noise.

Xiaomi’s Android 13+ models (e.g., Xiaomi 13 Ultra, POCO F5) add Dynamic Volume, which analyzes the contents of the audio stream and amplifies quiet moments (useful for podcasts and calls). Activates in Settings β†’ Sound β†’ Dynamic Volume.

⚠️ Warning: Resetting the sound settings will remove all custom equalizer presets and volume levels from the engineering menu!

How to roll back the MIUI update if it ruins the sound?
1. Go to Settings β†’ About β†’ System Update. 2. Tap 10 times on the MIUI logo, the developer menu will open. 3. Select the Delete update package. 4. After the restart, the system will return to the previous version. Importantly, this method only works if you have not confirmed the installation of the update (do not click "Reboot now").

5. Cleaning speakers and checking hardware problems

If the sound suddenly becomes quieter, the problem may be physical: clogging of speakers, damage to the membrane or oxidation of contacts.

  • πŸ” Blockage check: flash a flashlight into the speaker's grille. Do you see hair, dust or debris? Carefully remove them with a soft brush or compressed air (do not use toothpicks!).
  • 🎡 Speaker test: type in the phone application ##786## β†’ Select Speaker Test. If one of the speakers sounds quieter, the hardware problem is.
  • πŸ”Œ Check the headphone jack: plug the headphones and move the plug a little bit. If the sound comes, it disappears - the contacts have oxidized (need to clean with alcohol).

On models with stereo speakers (Xiaomi 12 Pro, POCO X5 Pro) the upper speaker is more likely to clog (it is closer to the microphone and collects dust).

  1. Turn off the phone.
  2. Use a spray of compressed air (keep at a distance of 10 cm).
  3. If the dirt remains - carefully walk with a cotton swab dipped in isopropyl alcohol.

After cleaning, check the sound through a test call or music playback, and if the problem persists, it may be that the speaker membrane is damaged, in which case only a replacement at the service center will help.

πŸ’‘

If the sound is better after cleaning the speakers, but not perfect, try calibrating them through the engineering menu (section 2).

6.Alternative methods: from Bluetooth codecs to tape recorders

If the standard methods didn’t help, consider workarounds:

  • 🎧 Bluetooth codecs: on models with Android 10+ (Xiaomi 11/12/13, POCO F4/F5) turn on aptX HD or LDAC In Settings β†’ Connected devices β†’ Bluetooth settings β†’ Sound quality. These codecs transmit sound with less loss, which subjectively increases volume.
  • πŸ”Š External amplifier: for headphones you can use portable DAC (for example, Xiaomi USB-C to 3.5mm Adapter with amplifier. It bypasses the limitations of the smartphone and gives a clean signal.
  • πŸ“» FM-transmitter: if there is a quiet sound in the car, connect Xiaomi to the tape recorder via Bluetooth FM Transmitter (e.g. Baseus) FM Transmitter.The sound will be broadcasted through the radio frequency without loss.

For owners of POCO F3 GT or Black Shark (game smartphones Xiaomi) there is an additional feature: Game Turbo mode amplifies the sound in games by 15-20%.

If you often listen to music through Bluetooth speakers, check the codec settings on the device itself. For example, the Xiaomi Mi Portable Speaker has Outdoor Mode, which increases volume by 30% due to compression.

7. Root methods: modifying system files

For advanced users who are ready to get root rights, there are radical ways:

  • πŸ› οΈ Editing mixer_paths.xml: This file contains volume limits for all audio devices, and it can be modified using Root Explorer or Magisk Module.
  • πŸ”§ Custom core installation: some cores (e.g. FrancoKernel) remove sound restrictions.Risk: unstable system performance.
  • πŸŽ›οΈ Magisk modules: Audio Modification Library allows you to fine-tune volume levels without manually editing files.

Editing instruction mixer_paths.xml:

  1. Get root rights (via Magisk or TWRP).
  2. Download Root Explorer and go along the way: /system/vendor/etc/mixer_paths.xml.
  3. Find the lines with the parameters: <path name="speaker"> <ctl name="RX1 Digital Volume" value="84" /> <ctl name="RX2 Digital Volume" value="84" /> Change the value to 92 (maximum 96, but risk of distortion).
  4. Save the file, set the rights to 644, and restart the phone.

⚠️ Attention: Incorrect editing mixer_paths.xml It can cause loss of sound completely or looping of the boot!

πŸ’‘

Root methods maximize volume, but they are not warranty-free and can disrupt system stability, and only use them if other methods have not worked.

FAQ: Frequent questions about Xiaomi sound

πŸ”Š Why After Updating MIUI sound became quiet?
Xiaomi often introduces new volume limits in fresher versions of MIUI, especially for European firmware (due to EU Volume Limit norms).Solutions: Reverse to the previous version of MIUI (section 4). Install global firmware instead of European (via Fastboot). Use a sound booster (section 3).
🎧 How to increase the volume in Bluetooth headphones?
For Bluetooth headphones: Turn on aptX HD or LDAC in Bluetooth settings. In the headphone app itself (e.g. Xiaomi Earbuds), activate Enhanced Bass mode. Use ViPER4Android with a Bluetooth profile. If the sound is quiet in only one ear, clear the mesh headphone mesh or reset them.
πŸ“ž Why the person can’t hear me when I call?
The problem may be: Microphone: check it for blockage (section 5). Networks: switch from 4G on 3G In Settings β†’ SIM-maps and mobile networks β†’ Preferred network type. Sound settings: In the engineering menu, increase the Sph level to 120. POCO X3 Pro and Redmi Note 10 have a microphone bug when VoLTE is active.Solution: disable Improved Calls in Settings SIM-map.
πŸ”Š Can the alarm clock be increased?
The alarm clock in MIUI has a separate regulator: Open the Watch app β†’ Alarm clock. Slip on the bell icon next to the time β†’ move the slider to maximum. Activate the option to gradually increase volume (the alarm will start quiet and build up). If the sound is still quiet, install a third-party application (for example, Sleep as Android) and select your audio file for the signal.
🎡 Why does music get distorted at maximum volume?
Distortions (wheezing, crackling) are caused by: Clipping: the signal exceeds the speaker's capabilities. Solution: reduce the volume by 10-15% Or use an equalizer to lower the low frequencies: MP3-bitrate 192 kbps are distorted when amplified. Resave tracks to 320 Kbps. Hardware restrictions: on Redmi 9A and POCO C31 They're cheap speakers that can't handle high loads. Solution: use headphones.
