How to increase the sound on the Xiaomi Redmi phone: from standard settings to hidden features

Are you missing out on the big talk because of the quiet sound on Xiaomi Redmi? The music in your headphones sounds like whispers and notifications have to be solved by vibration? The problem of low volume is familiar to many smartphone owners of this line β€” especially on budget models like the Redmi 9A or Redmi Note 10, where the manufacturer has saved on speakers. But don't be quick to blame the device: in 80% of cases, the sound can be amplified without repair.

In this article, we'll look at all the ways you can do it, from basic MIUI settings to hidden menu options and third-party utilities, how to raise the volume of calls, media, alarm clocks, and even the microphone (if you're not hearing well), and for advanced users, instructions for editing system files and calibrating speakers.

Important: The methods vary in complexity and risk: Start with safe (sections 1-3), and if you don’t get results, move to advanced (sections 4-6), and some methods will require root rights or a computer.

1. Standard volume settings in MIUI

The first thing to check is if the sound levels are lowered, and MIUI has separate regulators for different types of audio, and often users accidentally hit them.

Open the notification bar and tap the volume icon (or hold the volume button on the sidebar). A menu with three sliders will appear:

  • πŸ”” Call – Volume of incoming calls and notifications;
  • 🎡 Multimedia - music, video, games;
  • πŸ””β° Alarm clock – the sound of the alarm clock.

Make sure all sliders are shifted to the right until the end. If the sound is still quiet after that, go to Settings β†’ Sound and vibration β†’ Additional settings and check:

  • πŸ”Š Amplify the sound in headphones (turn on if you use wired headphones);
  • 🎧 Audio effects – Turn off the equalizer, it can turn down the volume;
  • πŸ“ž Loud Communication – Turn on to amplify the sound during calls.

πŸ’‘

If the sound is gone after the headphones are plugged in, clean the 3.5mm (or Type-C) jack of dust with a toothpick. Often the contacts become oxidized and the phone doesn't see the headset.

2. Equalizer and audio effects setup

MIUI has a system equalizer built in, which can by default suppress high or low frequencies, making the sound seem quieter, to calibrate it:

  1. Go to Settings β†’ Sound and vibration β†’ Audio effects.
  2. Select the user profile.
  3. Lift sliders 3-6 dB for 100Hz, 1 kHz and 10 kHz frequencies.
  4. Save the settings as a new preset (e.g., "Maximum").

If your Redmi model doesn’t have a built-in equalizer (like the Redmi 8A), install a third-party app like Equalizer FX or Wavelet from Google Play.

  • πŸŽ›οΈ Set up frequencies separately for speakers and headphones;
  • πŸ”Š Enable virtual subwoofer (enhances low frequencies);
  • 🎧 Use presets for different genres of music.

3. Checking physical speakers and connectors

If the sound is quiet in only one speaker or when you connect the headphones, the problem may be hardware.

  1. Speaker test: Call your phone from another device and check if the top and bottom speakers are working (on stereo models, such as the Redmi Note 11 Pro).
  2. Headphone check: connect them to another phone, if the sound is quiet and there is a problem in the headset.
  3. Clean connectors: Use a flashlight to inspect 3.5mm or Type-C for debris. Blow in compressed air if necessary.

If the speaker wheezes or the sound is interrupted, it may indicate:

  • πŸ’§ Moisture ingestion (even if the phone is not sinking, condensation from temperature drops can oxidize contacts);
  • πŸ”Š Damage to the speaker membrane (often after falls);
  • πŸ”Œ Problems with the plume (requires disassembly of the phone).
What to do if the speaker is not working at all?
If the speaker doesn't make any sounds, try resetting your phone to factory settings (Settings β†’ Phone β†’ Settings β†’ Reset). If that doesn't work, contact the service center - you'll probably need to change the speaker or audio chip.

4. Engineering menu: hidden sound settings

Xiaomi Redmi has an engineering menu that allows you to manually increase the volume above the system constraints, which works on 90% of models, but requires caution – incorrect settings can lead to distortion of the sound or damage to the speakers.

To open the engineering menu:

  1. Open the phone app.
  2. Enter the code ##36446337##
  3. Select Hardware Testing β†’ Audio β†’ LoudSpeaker Mode.

In this section you will see the parameters for different scenarios:

ParameterDefault valueRecommended valueDescription
Ring140–160180–200Loudness of the call
Media128–140160–180Loudness of music/video
Sip120–130150–160Volume of VoIP calls (WhatsApp, Telegram)
Mic200–220230–250Microphone sensitivity

Type in new values and press "Set." After that, restart the phone. If the sound becomes distorted (wheezing, crackling), go back to the engineering menu and reduce the values by 10 to 20 units.

Record the current parameters |Do not raise the volume by more than 30% of the standard values |Check the sound after each change |Reboot the phone after settings-->

5. Sound amplification applications

If standard methods don't work, try specialized utilities. They work on two principles:

  1. Software amplification – increase the volume due to algorithms (may lead to distortions);
  2. Driver correction – change system parameters (requires root).

Top.-5 Applications for Xiaomi Redmi:

  • πŸ”Š Volume Booster GOODEV β€” Simple booster with presets for different scenarios;
  • 🎧 Precise Volume – allows you to set the volume to within 1%;
  • πŸ› οΈ ViPER4Android β€” Advanced audio processor (root needed);
  • πŸ“± SoundAssistant – separate regulators for each application;
  • πŸ”‡ Equalizer & Bass Booster – Equalizer and Amplifier combo.

To install ViPER4Android (the most powerful tool) follow the instructions:

  1. Download APK from the official website (vipersaudio.com).
  2. Install Magisk and the ViPER4Android FX module.
  3. In the application settings, select the "Legacy Mode" driver.
  4. Activate Master Limiter and raise Volume Boost to +6 dB.

πŸ’‘

ViPER4Android can conflict with MIUI system audio drivers. If the sound is completely lost after installation, turn off the module in Magisk and restart the phone.

6. editing system files (for advanced)

If you're willing to take risks, you can manually change the audio configuration files in the system, which is a method that maximizes amplification, but requires root rights and backup.

Instructions for Xiaomi Redmi:

  1. Install Root Explorer or any file manager with superuser rights.
  2. Go to /system/vendor/etc/
  3. Find the file. mixer_paths.xml (or mixer_paths_tasha.xml new-model).
  4. Open the file in the text editor and find the lines with the parameters: <path name="speaker"> <ctl name="RX1 Digital Volume" value="84" /> <ctl name="RX2 Digital Volume" value="84" />
  5. Increase your value to 90-95 (not higher!).
  6. Save the file and restart the phone.

After that, the loudspeaker will increase by 20 to 30 percent, and warning: if you set the readings above 95, the sound will be distorted and the speakers may fail.

πŸ’‘

Before editing system files, backup your phone via TWRP or Titanium Backup, which will allow you to restore your phone if something goes wrong.

7. Hardware modifications (at your own risk)

If the software methods fail, there's still a physical rework, and these methods require disassembling the phone and can be insecure, but sometimes they're the only solution for older models like the Redmi 4X or Redmi 5A.

Modification options:

  • πŸ”§ Replacement speaker – AliExpress sells more powerful speakers (look for the phone model);
  • πŸ”Š Installation of an external amplifier, such as a chip TPA3110 headphone-connected;
  • πŸ”‹ Salting of an additional resistor - increases the voltage on the speaker (requires knowledge of electronics).

To replace the speaker, you will need:

  • πŸ› οΈ Setting screwdrivers (T2, T3, T4);
  • πŸ”₯ Hair dryer;
  • 🧲 Screen suction cup;
  • πŸ” Loop for contact checks.
Where can I buy spare parts for Redmi?
On AliExpress, search for "Redmi [model] speaker replacement." The average speaker price is $3-7. Pay attention to reviews: often Chinese sellers send unoriginal, low-quality parts.

Frequent Questions (FAQ)

Why is the sound so quieter after the MIUI update?
In the new MIUI 13/14 versions, Xiaomi has tightened volume limits due to European regulations (EU Directive 2019/771). To return to the previous level, roll back to MIUI 12.5 or use the methods from Section 4 (Engineering Menu).
Can I increase the volume of the microphone for calls?
Yes. In the engineering menu (#36446337##), find the Mic parameter and increase it to 230-250, and check if the microphone hole is covered with a cover or film.
Why is the sound quiet in headphones, but normal in dynamics?
This can be caused by: Headphone malfunction (check on another device); Contact oxidation in the 3.5 mm connector; Restriction in MIUI settings (turn off "Safe Mode for Headphones" in Settings β†’ Sound).
How to reset the sound settings to the factory?
Go to Settings β†’ System β†’ Reset β†’ Reset all settings. This will return the standard volume values, but will not delete your files. To completely reset, select "Erase all data".
Is it safe to use amplifiers?
Most Google Play apps (like Volume Booster) are safe, but they can distort the sound at high volume; some require root, which cancels the warranty; If used at maximum volume, speakers can burn out for long periods of time; we recommend testing such applications for no longer than 10-15 minutes in a row.

If none of the methods worked, the problem may lie in a hardware malfunction – contact the Xiaomi service center or a proven wizard. Remember: the older the Redmi model, the higher the probability of wear of the speakers (average life is 3-4 years).
