How to increase the volume of the speaker on Xiaomi Redmi: from settings to engineering menu

Have you noticed that the volume of the speaker on your Xiaomi Redmi leaves much to be desired? Music sounds quiet, and in a noisy room it is difficult to hear the interlocutor? The problem is not always in the hardware β€” it can often be solved software. In this article, we will discuss 8 working ways to increase the volume, from basic settings to hidden functions of the engineering menu.

It’s important to understand that Redmi models with a single speaker (like Redmi 9A or Redmi 10A) have stronger physical volume limits than flagships with a stereo system (Redmi Note 11 Pro+ or POCO X5 Pro). However, even on budget devices, you can achieve improvements of 20-40% without risk to technology.

Before you start setting up, check the obvious: is the speaker covered with a cover or a protective film, is not lattice clogged with dust. If that's not the problem, read on. We'll start with the safest methods and gradually move on to more advanced ones.

1. Optimization of system sound settings

The first step is to check the basic parameters that many users miss. Go to Settings β†’ Sound and vibration and pay attention to the following points:

  • πŸ”Š Media volume: users often confuse it with the volume of the call.
  • 🎡 equalizer MIUI: Activate it and select the preset "Bas" or "Rock" - they amplify the low frequencies, which subjectively makes the sound louder.
  • πŸ”„ Adaptive sound: Turn off this feature if it is active – it automatically lowers volume in quiet rooms.
  • πŸ“± Do Not Disturb: Check if it is activated in the schedule (can block notifications and sounds).

Some Redmi models (like the Redmi Note 12 Pro+) have a separate "Amptimize Sound" option β€” turn it on. If you don't, try updating MIUI to the latest version: new firmware often adds additional audio settings.

πŸ“Š What kind of Redmi model do you have?
Redmi 9/10 series
Redmi Note 11/12
POCO X3/X4
Redmi 13C/14
Another model

So remember to set up individual apps, for example, YouTube or Spotify might have a volume control that limits the maximum level, and go to the player's settings and check:

⚠️ Warning: If the sound starts to distort after the settings change (wheezing, crackling), return the equalizer parameters to their original state.

2. Use of third-party sound amplifiers

If the system settings didn’t work, try specialized applications that work at the software level of sound processing and can increase volume by 15-30%.

  • πŸ”Š Volume Booster GOODEV: A simple booster with presets for music, video and games.
  • πŸŽ›οΈ Equalizer FX: Advanced equalizer with bass amplification and high frequencies.
  • πŸ“± Precise Volume: allows you to adjust the volume more accurately (up to 100 gradations instead of the standard 15.
  • 🎧 ViPER4Android: It's a powerful audio processor, but it requires Magisk and manual tuning.

Install one of the applications (for example, Volume Booster) and follow the instructions:

Open the app and give access to media

Select the profile "Music" or "Video"

Move the gain slider 20-25% (not the maximum!)

Activate the Auto Start option for automatic amplification-->

Important: Don't set the amplification to 100%, which will distort the sound and can damage the speakers. Optimal range is 20-35%. Also turn off the amplifier when listening through the headphones so that you don't damage your hearing.

AnnexStrengthening (max.)Root is required.Suitable for
Volume Booster GOODEV+30%No.Music, video, games.
Equalizer FX+25%No.Players, YouTube
Precise Volume+15%No.Thin volume setting
ViPER4Android+40%Yes (Magisk)Advanced sound processing

Before installing the sound amplifier, back up the sound settings in MIUI (Settings β†’ Sound β†’ Three Dots β†’ Export settings).

3. Activate hidden functions through the engineering menu

Xiaomi Redmi smartphones have a hidden engineering menu where you can change the settings of speakers. This method does not require root rights, but be careful: the wrong settings can damage the speaker.

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 menu, you will see the options "Max Vol" and "Type" and the following values are relevant for most Redmi models:

  • πŸ”’ Max Vol: Increase the value from 150 to 160-170 (no higher than the value!).
  • 🎡 Type: If you have stereo speakers, select "Dual Speakers".
What to do if the engineering menu does not open?
On some MIUI firmware, code ##36446337## may not work. Alternatives: 1. Try code ##4636## β†’ "Audio" β†’ "Loudspeaker." 2. Install the MTK Engineering Mode app (for MediaTek-based devices). 3. If nothing helps, your model may be blocking access to the engineering menu at the software level (relevant to the new Redmi on Snapdragon 8 Gen 2).

When you change the settings, restart your smartphone. If the sound gets worse (wheezing), return the values to the original state. Also note the "Impedance" parameter: if it is below 8 Ohms, do not increase the Max Vol above 160.

⚠️ Note: On Redmi models with Qualcomm Snapdragon processor (e.g. Redmi Note 12 Pro)+) The menu may contain other parameters, but don't change the values in the Receiver or Headset sections, which will cause problems with the sound in the headphones.

4. Update of firmware and sound drivers

Often low volume is associated with outdated audio drivers or firmware bugs. Xiaomi regularly releases updates to fix sound problems.

  1. Go to Settings β†’ About the phone β†’ System update.
  2. Click on "Check Updates" and install the latest version of MIUI.
  3. After the update, reset the sound settings: Settings β†’ Sound β†’ Three points β†’ Reset settings.

If the official update didn’t work, you can try custom firmware (like Pixel Experience or LineageOS), which often has better audio optimization, but this requires unlocking the bootloader and installing it via TWRP, which voids the warranty.

πŸ’‘

On Redmi models with MediaTek Helio G (such as Redmi 10 or POCO M4 Pro) after upgrading to MIUI 14, many users noted a 10-15% improvement in volume due to driver optimization.

Also check if the system audio services are disabled.

  1. Go to Settings β†’ Applications β†’ Application Management.
  2. Press three points. β†’ "Show system-based".
  3. Find MIUI Audio Service and make sure it's not turned off.

5. Cleaning speakers and checking hardware problems

If the software didn't work, the problem could be the physical contamination of the speakers, the dust, the hair, the moisture, eventually accumulate in the grille, making the sound worse.

  • 🧹 Use a soft brush (for example, for makeup) or compressed air (a balloon!
  • πŸ’§ If the speaker is wet, dry it with silica gel (put the phone in a bag with balls for 12-24 hours).
  • πŸ”Š To check the speaker, use the test: enter the code ##0*## in the phone number and select Speaker".

If the sound has not improved after cleaning, hardware malfunctions are possible:

  • πŸ”§ The contact speaker has detached (relevant after falls).
  • πŸ”‹ Problems with the audio amplifier on the motherboard.
  • πŸ”Š Wear of the speaker (characteristic for devices older than 3 years).

For a diagnosis, contact the service center. The average cost of replacing a speaker with a Redmi is 800-1,500 rubles (depending on the model). On the Redmi Note 11 Pro and later, stereo speakers are often installed, and replacing one will cost less than both.

⚠️ Warning: If the speaker starts wheezing or stops working after cleaning, you may have damaged the membrane.

6.Alternative methods: from Bluetooth speakers to Magisk modules

If none of these methods worked, consider alternative solutions:

  • 🎧 Bluetooth speaker or headphones: connect an external device to play back sound. Redmi supports aptX codecs and AAC, Provides good quality.
  • πŸ”Š USB-C/Type-C Dynamics: some models (e.g. Redmi Note) 12 Pro+) Support sound output through the connector USB-C. Connect an active column or adapter.
  • πŸ› οΈ Magisk modules: For rooted devices, there are modules like the Audio Modification Library that deeply optimize sound.
  • πŸ”„ Factory reset: in rare cases, the problem is a conflict of system files. Back up and reset to Settings β†’ The phone. β†’ Resetting settings.

For owners of a POCO F5 or Redmi K60, there's another option, which is to use Dolby Atmos, which improves spatial sound, which subjectively makes it louder, to activate:

  1. Install Dolby Atmos from Google Play (if it is not in the firmware).
  2. Select the "Music" or "Cinema" profile.
  3. Activate the option β€œAdaptive Sound” (despite the name, it works differently in this context than in MIUI).

If you decide to root, consider that this is:

  • 🚫 Deprives you of security.
  • πŸ”“ Requires unlocking the bootloader (on the new Redmi, it takes up to 7 days to wait for confirmation from Xiaomi).
  • ⚠️ It may lead to a β€œbrick” (breakdown) with incorrect actions.

7. Volume comparison on different Redmi models

The volume of the speakers depends on the Xiaomi Redmi model, and in the table below is a comparison of popular devices by sound level (in decibels, dB) and the presence of a stereo system:

ModelLoudness (dB)StereodynamicsFeatures
Redmi 9A / 10A78–80No.One speaker, weak bass.
Redmi Note 11 / 11S82–84Yes.Good stereo, but medium high frequencies
POCO X4 Pro85–87Yes.Best sound in its segment
Redmi Note 12 Pro+88–90Yes (JBL)The loudest sound among Redmi
Redmi 13C80–82No.Improved speaker compared to 9A

As you can see from the table, the Redmi Note 12 Pro+ with JBL speakers delivers the loudest sound. If that's critical for you, look for models with JBL or Dolby Atmos certification when choosing a new smartphone.

On budget models (e.g. Redmi 10A), it is physically impossible to achieve the volume of flagships due to the small size of the speaker and the absence of a second module, in which case the best solution is to use external speakers.

FAQ: Frequent questions about volume on Xiaomi Redmi

Why is the sound so quieter after the MIUI update?
This is a common problem, especially when switching to MIUI 14, because of the new maximum volume limits for security purposes. Try: Reset the audio settings to Settings β†’ Sound β†’ Three Dots β†’ Reset. Reverse to the previous firmware version (if you know how). Use a sound amplifier (like Volume Booster). If nothing helps, write in support of Xiaomi through the Feedback app β€” sometimes they release patches for such bugs.
Can I increase the volume of the speaker (not the main one)?
Yes, but it's more complicated. The speaker (for calls) is configured via the engineering menu: Open the engineering menu (code ##36446337##.) Go to Audio β†’ Normal Mode β†’ Receiver. Increase Max Vol to 140-150 (no higher than the one above!). ⚠️ Warning: Incorrect settings can cause the person you're talking to to be hard to hear, not yours. Test changes during the call.
Why is the sound distorted at maximum volume?
It's because of this: πŸ”Š Overloading speaker – he is physically unable to reproduce sound of such power. 🎡 Incorrect equalizer settings (too much bass or high frequencies). πŸ› οΈ Speaker membrane damage (e.g. after falling) Solution: Turn down volume by 10 to 15 percent. Reset the equalizer settings. Check the speaker for damage.
How to check if the second speaker on Redmi is working with stereo sound?
On dual-speaker models (like the Redmi Note 11 Pro), the second module often only works in landscape mode or when playing media. To check: Turn on YouTube videos and flip the phone horizontally. Close the top speaker with your finger - the sound should be quieter. Repeat the same with the bottom speaker. If one of the speakers does not work, try: Clean it of dust. Reset the audio settings. Contact the service (possibly the plume has gone).
Is it safe to use sound amplifiers all the time?
Long-term use of amplifiers (especially at maximum) can be: πŸ”‹ Reduce the service life of the speaker due to overheating. 🎧 Damage hearing when listening to headphones. πŸ› οΈ Induce distortions at high volume. Recommendations: Do not exceed the amplification by more than 25%. Take breaks every 30-40 minutes of listening. Use amplifiers only when necessary (for example, outside).
