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

Are you tired of putting your phone to your ear to hear someone while you're on the phone? The low volume problem of the Xiaomi Redmi speaker is one of the most common problems with users. The reasons can range from factory constraints to dust clogging the speaker, but the good news is that you can turn up the volume yourself in 90% of cases without having to use a service center.

In this article, we'll look at 7 proven ways, from basic Android settings to engineering menus and customized applications. Importantly, not all methods are equally safe. For example, changing the parameters in the engineering menu can damage the speaker when used at maximum volume for long periods of time, so we'll explain the risks of each option in detail and give recommendations on how to minimize them.

Before you start setting up, make sure that the problem is not hardware. Do a simple test: turn on speaker while you're calling. If the sound is clear and loud through the main speaker, and if the sound is quiet or distorted through the conversational speaker, then it's the software limitations. If the sound is bad in both modes, it may be physically damaged (for example, after a fall or moisture).

1. Checking basic sound settings

Start with the obvious -- check to see if the volume level is down in the system settings. Xiaomi Redmi has separate regulators for media, alarm clock and calls. Often users accidentally turn down the volume of a speaker without noticing it.

How to check:

• 🔊 Open the Settings. → Sound and vibration.
• 📞 Go to Loudness and make sure the Call Slider (or Speaker) is set to maximum.
• 🔄 Check if Do Not Disturb or Quiet mode is activated in the notification curtain.

If the slider is already at its maximum, but the sound is still quiet, try resetting the sound settings to the factory.

1. Go to Settings → System and device → Resetting.
2. Select Resetting Sound Settings (not to be confused with a full reset!).
3. Confirm the action and restart the smartphone.

⚠️ Note: Some Redmi models (e.g. Redmi Note 10 Pro or Redmi 12) after the update MIUI Reset the individual volume settings for each profile (regular, meetings, on the street!

2. Cleaning dynamics from dust and debris

Often the reason for the quiet sound is trivial — clogging speaker. On Xiaomi Redmi, the speaker is located at the top of the screen (near the front camera), there is easy to get dust, villi from your pocket or cosmetics residue, you can clean it without disassembling the phone.

Cleaning methods:

• 🧹 Use a soft brush (like makeup) or a toothpick with cotton wool. Carefully run the speaker on the grille without pressing hard.
• 💨 Compressed air canister (sold in electronics stores) Hold the cylinder vertically so as not to damage the speaker with condensate.
• 🎵 Turn on the speaker test through the service menu (we will talk about it below) and check if the sound has improved after cleaning.

Do not use sharp objects (needles, knives) - they can damage the speaker membrane. Also avoid wet wipes: liquid can leak in and cause corrosion.

3.Use of the Engineering Menu (MTK/Qualcomm)

The engineering menu is a hidden settings section where you can manually change the audio settings, including the volume of the speaker.The method works on most Xiaomi Redmi models, but requires caution: improper settings can lead to distortion of the sound or damage to the speaker.

How to open the engineering menu:

• 📱 For Qualcomm processors (most Redmi): Enter the Phone code ##4636##, then select Audio information → Audio HW Info.
• 📱 For MediaTek processors (e.g., Redmi) 9A, Redmi 10A): Enter #36446337##.

In the Audio menu, find the Normal Mode or Headset Mode (for a conversational speaker) section, and you can change the settings here:

• Sph Max Vol - Maximum microphone volume (does not affect the speaker)
• Speech RX Vol – Volume of the speaker (increase gradually, in increments of +1).
• Speech TX Vol is the volume of the microphone for the interlocutor.

Do not increase the value by more than 5 units at a time.

Check the sound after each change.

Do not save settings if distortions are heard

Reboot your phone after the changes-->

⚠️ Attention: On models with MIUI 14+ You can block access to the engineering menu, and in this case, try using apps like this. MTK Engineering Mode (for MediaTek) or Shortcut Master to find hidden menus.

4.Applicants for sound amplification

If you don't want to go through the settings, you can use third-party apps that are equalizers that amplify certain frequencies, or directly increase the volume of system sound, and it's important to choose proven programs so that you don't run into viruses.

5. Update MIUI and reset settings

Sometimes the quiet sound problem is solved by a banal firmware update. Xiaomi regularly releases patches that fix sound bugs. For example, MIUI 13 had a bug that caused the volume of the speaker to reset after the reboot. MIUI 14 fixed this bug.

6. Checking for hardware malfunctions

If none of the software methods helped, perhaps the problem is in the hardware.The most common faults of the talk speaker on Xiaomi Redmi:

• 🔊 Membrane damage – the sound is quiet and distorted, even at maximum.
• 💧 Corrosion of contacts – after moisture hits (even if the phone does not sink, moisture can penetrate through microslits).

How to diagnose:

1. Call your phone and put it on speakerphone, and if the sound is normal through the main speaker and the sound is quiet through the conversational speaker, the problem is that speaker.
2. Shake the phone near your ear when you ring. If you hear any noises (crackling, wheezing), it's likely that dust or moisture has entered the room.
3. If the sound is clear and the speaker is not, it's the hardware.

1. Go to Settings. → SIM-maps and mobile networks.
2. Choose yours. SIM-Map and activate VoLTE and Improved Call Quality.
3. Reboot the phone.
