How to check the speaker on Xiaomi phone: a complete guide with tests and tips

The speakers in Xiaomi smartphones are one of the most vulnerable components that can eventually fail due to moisture, mechanical damage or factory defect. Sound problems manifest themselves in different ways, from complete lack of sound to distortion, wheezing or uneven volume. If you notice that your Redmi, POCO or Mi has become worse at playing music, voice in calls or system notifications, this is a reason to conduct a diagnosis.

In this article, we’ll break down all the available ways to check speakers on Xiaomi phones, including standard tests, hidden engineering menus, and third-party apps. You will learn how to distinguish between a software failure and a hardware breakdown, what tools to use for accurate diagnosis, and what to do if the speaker really does not fault. POCO F5), where each speaker requires a separate approach.

Before you take your phone to the service center, try to identify the problem yourself, because in 60 percent of cases, you can fix the malfunction without repair by resetting the settings or cleaning the connectors, and start with the simplest methods and gradually move to advanced ones.

1. Quickly checking the speakers through standard functions

So, starting with basic tests that don't require any additional software, these methods can help you identify obvious problems with sound, such as no signal or distortion at all.

The first thing you need to do is check the volume and modes of sound in the settings. Sometimes users accidentally activate No Sound mode or reduce the volume to a minimum through the side buttons.

• 🔊 Volume slider in Settings → Sound and vibration are set to maximum.
• 📵 Do Not Disturb Mode is disabled (check in the notification curtain or Settings) → Notifications).
• 🎧 The phone does not have headphones inserted – some Xiaomi models automatically redirect the sound to the headphones, even if they are connected incorrectly.

If the settings are all right, proceed to testing the speakers:

1. Call another phone and check if the voice of the interlocutor is heard through the upper (talk) speaker.
2. Turn on music or videos on YouTube – the sound should come from the bottom speaker. On models with stereo sound (e.g. Xiaomi 12T), check both speakers.
3. Record a voice message and listen to it – this will help to identify distortions in the microphone and dynamics at the same time.

If the sound is missing or distorted, move on to the next section. If the speakers are working normally but the sound is too quiet, the problem may lie in the equalizer settings or a clogged headphone jack (even if the headphones are not connected, the contacts may have oxidized).

2.Using the built-in speaker test in MIUI

Xiaomi has provided a hidden test of hardware components, including speakers, which is available without installing third-party applications, this method works on most models with a shell MIUI 12 and newer (for example, Redmi Note 11, POCO X4 Pro, Xiaomi 13 Lite).

To run the test:

1. Open the phone app and dial the combination: ##6484##
2. The Manual Test menu will appear on the screen.
3. Select Loud Speaker to check the bottom speaker or Receiver for the top speaker.
4. Press Start Test – the phone will play the test sound.

If the sound is missing or interrupted, the system will show a FAIL error.

• 🔧 Try repeating the test after restarting your phone.
• 📱 Check if the sound is blocked by a cover or protective film (especially important for models with speakers on the end, like the Xiaomi Mix 4).
• 🔊 Make sure there is no dust or moisture in the speaker - gently blow the hole (do not use sharp objects!).

If the test shows PASS, but the sound is still bad, the problem may be the firmware or the settings of the sound processor, in which case resetting the audio settings (see section 5).

3. Verification through the engineering menu (for experienced users)

The Engineering Menu is a hidden settings section that allows you to test hardware components at a low level.It is available on all Xiaomi phones, but requires caution: wrong actions can lead to malfunctions of the device.

To open the engineering menu:

1. Open the phone app and type in: ##4636###
2. Select the Testing (Testing) item.
3. Go to the Audio section (Sound).
4. In the test list, find the Loud Speaker (bottom speaker) and the Earphone (top speaker/tube).
5. Click on each item and the phone will play back the test signal.

In the engineering menu you can also check:

• 🎛️ Signal Level – If the volume slider on the menu doesn’t match the actual sound, it indicates a software failure.
• 🔄 Balance of speakers – on models with stereo sound (for example, Xiaomi) 12S Ultra) make sure that both speakers are equally loud.
• 📊 Frequency Characterization – if the sound “buzzes” or “squeaks”, one of the frequency ranges may be damaged.

If the speakers pass the test in the engineering menu, but there is no sound in real conditions, the problem may lie in:

• Application conflict (for example, third-party players or messengers block sound).
• Damage to system files after MIUI update.
• Faulty sound chip (requires diagnosis in the service center).

4. Diagnostics with the help of third-party applications

If standard methods have not helped to identify the problem, use specialized applications for testing speakers, which allow you to check the sound at different frequencies, measure the level of distortion and compare the performance of the left / right speakers (for stereo models).

Top.-3 Apps to check speakers on Xiaomi:

How to use Phone Check and Test:

1. Install the application and open it.
2. Go to the Speaker section (Dynamics).
3. Press Start Test – the application will play sounds of different tones.
4. If the sound is interrupted or absent, the app will show an error.

For models with stereo speakers (such as the Xiaomi 13 Pro or POCO F4 GT), use the Speaker Test:

• 🔊 Select Stereo Test Mode.
• 🎵 The app will alternately play the sound through the left and right speakers.
• 📊 Compare volume and sound quality – a difference of more than 30% indicates a malfunction of one of the speakers.

💡

If the app shows a speaker error but the sound in phone calls is working normally, the problem may be the system limitations of MIUI. Try temporarily disabling the Adaptive Sound function in the settings (Settings → Sound → Adaptive Sound).

5. Check for physical damage and pollution

Mechanical damage or contamination are common causes of speaker failure, and even a little dust or moisture can cause sound distortion or complete failure.

• 🕳️ Hole clogging – use a flashlight to peer into the speaker grille. If dust is visible, carefully remove it with a soft brush (do not use toothpicks or needles!).
• 💧 Oxidation traces - if the phone falls into water, the speakers' contacts may show green or white spots.
• 🔧 Membrane detachments – if the sound “bursts” or wheezing appears, it is possible that the membrane speaker is damaged.

For waterproof models (such as Xiaomi 13 or Redmi Note 12 Pro+) check:

• 🛡️ The state of the sealing rubber bands around the speakers (they could dry or shift).
• 🚨 Moisture indicator - on some models it is located next to the SIM-If the light went red, the phone came into contact with the water.

💡

If the speaker wheezes or the sound is interrupted when pressing the phone body, it indicates mechanical damage (detachment of contacts or a crack in the membrane), in which case repair in the service center is inevitable.

For the prevention of pollution:

• 🧹 Regularly clean the speakers holes with compressed air (a canister for cleaning equipment).
• 🚫 Avoid using your phone in dusty or wet conditions (such as construction or bathroom).
• 📱 Do not put the phone down on soft surfaces (dust and pile can clog the grille).

6. Resetting sound and firmware settings

If hardware tests show no problems, but the sound is still not working correctly, the cause may be software failures, in which case a reset of the audio settings or a complete flashing of the phone will help.

Resetting sound settings (does not delete data):

1. Go to Settings → System → Resetting settings.
2. Select Resetting of sound settings (on some models this item may be called Resetting of media settings).
3. Confirm the action and restart the phone.

Reset to factory settings (deletes all data, make a backup!):

1. Go to Settings → About the phone → Reset settings.
2. Choose to erase all data.
3. Wait until the process is completed (the phone will restart).

If the reset doesn’t work, try reflashing your phone through the Mi Flash Tool:

• 📥 Download the official firmware for your model from the Xiaomi website.
• 🔧 Install the Mi Flash Tool on your PC and connect your phone in Fastboot mode (clip Volume Down). + Power with the phone turned off).
• 🖥️ Follow the instructions of the program for installing firmware.

7. When to contact the service center

If all of the above methods didn’t work, the problem is likely hardware.

• 🔇 The speaker does not reproduce sound at all (even after firmware).
• 🔊 The sound is distorted or interrupted regardless of the settings.
• 💥 The phone fell or came into contact with water.
• 🔧 In the engineering menu, the dynamics test shows FAIL.

The cost of repairing speakers in Xiaomi depends on the model:

Before the service visit:

• 📋 Write it down. IMEI phone number (dial *#06#).
• 🔄 Make a backup copy of the data.
• 📄 Take a check or a warranty card (if the phone is guaranteed).

💡

If the phone is warranty, don't open it yourself, it will void the warranty. Even to clean the speakers, it is better to contact the service center.

In some cases, service centers offer free diagnostics (e.g., Xiaomi’s branded services or partner workshops), check this by phone before visiting.
