How to increase the volume of the Xiaomi speaker when talking: from settings to engineering menu

Are you tired of asking your partner to speak louder when you're calling Xiaomi? Bad hearing is one of the most common problems for smartphone owners of this brand, especially low-end and mid-range models. The reasons can range from factory volume limits to a clogging speaker or software failures. But the good news is that 90% of the time, you can solve the problem yourself without going to the service center.

In this article, we will discuss 7 proven ways to increase the volume of the speaker on Xiaomi, starting with basic settings and ending with advanced methods through the engineering menu. You will learn what parameters can be changed without risk to the phone and where caution is required. We will also tell you how to diagnose hardware malfunctions if the software methods do not help. All instructions are relevant for Redmi models, POCO and flagship Xiaomi series 11/12/13/14 based on MIUI 12/13/14.

Before you start settings, make sure that the problem is not due to external factors:

• 🔊 Check if the speaker is covered with a cover or finger during a conversation.
• 📶 Make sure the network signal is stable (with a weak signal, the voice may be interrupted).
• 🎧 Turn off Bluetooth headphones if they are connected.
• 🔄 Reboot your phone – sometimes it solves temporary sound failures.

If after these actions the problem remains, go to the methods below.

1. Volume settings through standard MIUI parameters

Start with the simplest one, checking the basic sound settings, and MIUI has separate regulators for media, alarm clocks, and calls that are often confused, and here's how to set the volume correctly for a speaker speaker.

Open the Settings app and go to the Sound and Vibration section, and here you're interested in two things:

• 📞 Loudness of calls – responsible for the volume of the incoming call (not to be confused with spoken volume!).
• 🗣️ Volume in conversation – this slider regulates the sound of the interlocutor during the call.

Move the speaker to the maximum, if it's already at its maximum, but still quiet, move on to the next step.

Also in this section, check out:

• 🔇 Is the Do Not Disturb mode disabled or the Quiet mode.
• 🎵 Is the audio amplification option enabled (if available in your version) MIUI).
• 🔄 In some models (for example, POCO X3 Pro) has a separate switch Adaptive sound - try turning it on/off.

⚠️ Warning: If the sound becomes distorted or wheezing after changing the settings, return the slider to its previous position.

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

If the standard settings didn't work, the next thing to try is the engineering menu.This is a hidden section where you can fine-tune audio settings, including microphone amplification and speaker. Xiaomi uses chipsets from MediaTek (MTK) and Qualcomm, and for each type of processor, the input to the engineering menu is different.

For MediaTek (Redmi 9, 10, Note 10, POCO M3, etc.):

1. Open the Phone app.
2. Enter the code: ##36446337## (or #4636## on some firmware).
3. Select Hardware Testing → Audio → Normal Mode.
4. Find the Sph (microphone) and Sph2 (dynamics) settings – increase the values by 10-20 units.

For Qualcomm (Xiaomi 11/12, POCO F3, Redmi K40, etc.):

1. Enter the code: ##4636###.
2. Go to Information → Audio.
3. Find Volume or Speaker Gain strings – increase the values gradually (no more than +5 dB at a time).

After the changes, restart the phone and check the sound. If the speaker starts wheezing or the sound becomes a robotic effect, put the values back in place.

Do not increase the volume by more than 20% of the standard value

Record the initial parameters before changing

Check the sound after each change.

Do not change the microphone settings (may impair the quality of voice transmission)-->

3. Installation of third-party applications to amplify sound

If you don't want to dig into the engineering menu, you can use specialized applications. They work like amplifiers, but it's important to choose proven programs to avoid damaging the phone. Here are 3 best options for Xiaomi:

How to use:

• 📥 Install one of the applications (for example, Volume Booster).
• 🔊 Start and turn on the call amplification mode.
• 🎛️ Adjust the slider to a comfortable level (not maximum!).
• 📞 Check the sound during the test call.

⚠️ Note: Amplifiers can reduce speaker life with prolonged use at maximum volume.

💡

Before installing third-party apps, check reviews - some programs contain ads or require unnecessary permissions.Optimum choice: apps rated 4.5+ and over 1 million downloads.

4. Cleaning dynamics from dust and debris

Often, the silent sound is caused by a physical clogging of the speaker, the dust, the fibers from the clothes or the cover, the moisture, all of these can block the sound waves, and you can clean it yourself, but you can do it carefully so you don't damage the membrane.

You'll need:

• 🧹 Soft brush (for example, for makeup).
• 💨 Compressed air container (optional).
• 🔦 Lighting lamp.
• 🧴 Alcohol wipes (do not use liquid alcohol!).

Step-by-step:

1. Turn off the phone.
2. Point the flashlight at the speaker - you will see a grid with holes.
3. Carefully walk the brush on the grid, removing visible debris.
4. If there is a can, short presses (no more than 1 second!) blow the speaker.
5. Wipe the area around the speaker with an alcohol napkin.

Never use toothpicks, needles or cotton cotton, which can damage the speaker membrane or push the debris deeper. If the sound has not improved after cleaning, the problem may be a hardware malfunction (for example, a departed contact or a damaged membrane).

5. Checking for hardware malfunctions

If all software methods have been tried, but the sound is still quiet or distorted, it could be a problem with the hardware.

• 🔌 Discarded contact – the speaker can work intermittently or quieter than usual.
• 🔊 Damaged membrane – the sound wheezes or is completely absent.
• 📱 Motherboard problems – sound disappears after a fall or impact.
• 🔋 Failure of the sound controller is rare, but occurs after unsuccessful firmware.

How to diagnose:

1. Connect headphones - if they sound normal, the problem is dynamics.
2. Call another phone and check if the person you are listening to hear you (if not, the microphone may be the problem).
3. Write down a voice memo – if the recording is quiet, but the sound is normal in the headphones, the speaker is to blame.

If you suspect a hardware malfunction, you should contact a service center: the average cost of replacing a speaker on Xiaomi is from 800 to 2000 rubles (depending on the model), self-repair without experience can damage plumes or boards.

💡

If you have a quiet sound after a phone falls, hits you, or gets moisture, you're 90 percent likely to have a hardware breakdown. Software won't help.

6. Update firmware and reset settings

Sometimes software bugs are the cause of quiet sound, especially after MIUI updates. Xiaomi regularly releases patches that fix sound problems, so first of all check the relevance of the firmware:

Go to Settings → About Phone → System Update. If a new version is available, install it.

• 🔄 Reboot the phone.
• 🔊 Check the volume in the conversation.
• 📱 If the problem persists, reset your settings (but back up first!).

How to reset the sound settings:

1. Open Settings → System and device → Resetting settings.
2. Select Reset all settings (does not delete files, only settings).
3. After restarting, reset the sound.

If the reset didn’t help, try retracing back to the previous version of MIUI (if the problem occurred after the update).

1. Download the old firmware from the official Xiaomi website.
2. Go to Settings → About Phone → MIUI version and tap 10 times on the MIUI logo to enable Additional settings.
3. Select Select a firmware file and specify the downloaded file.

⚠️ Attention: Firmware rollbacks may cause data loss or bootloader lock on some models!

7. Alternative solutions: headphones, Bluetooth, VoIP

If you can not increase the volume of the speaker, consider alternative ways of communicating:

• 🎧 Use wired headphones with a microphone – the sound will be clear, and the interlocutor will hear you better.
• 📶 Bluetooth headset – modern models (for example, Xiaomi Buds 4) support noise reduction.
• 💬 VoIP messengers (WhatsApp, Telegram, Viber) – Internet calls often sound louder than cellular communications.
• 📱 Turn on speakerphone (but note that others will hear the conversation).

For owners. POCO or redmi with IR-port has another life hack: connect wireless headphones through IR-Adapter (e.g. Xiaomi Bluetooth Audio Transmitter) This will allow you to listen to the interlocutor through headphones, even if the Bluetooth on the phone is broken.

If you make frequent calls in noisy places, consider buying an external microphone (such as a Boya BY-M1 or Rode VideoMic) that connects via a USB-C or 3.5mm connector and significantly improves voice quality.

💡

Speaker and Bluetooth headsets are the best temporary solutions if the speaker repair is delayed, but remember, long-term use of headphones at maximum volume is bad for hearing!
