How to check the speaker on the Xiaomi smartphone: full instructions with tests and tips

Sound problems are one of the most common smartphone malfunctions, but they're not always hardware-related. 60 percent of the time, software failures, incorrect settings, or clogging of the speaker are to blame. Before you carry the phone to the service center, you should check the Xiaomi speaker yourself, which will save time and money.

In this article you will find 7 Proven diagnostic methods, including hidden tests, check through the engineering menu and even methods for detecting physical damage, we will examine how to distinguish software failure from hardware failure, which Xiaomi models are more likely to suffer from sound problems (spoiler: Redmi Note) 8/9 and POCO X3 In the risk zone, what to do if the speaker is working, but the sound is distorted, and also a unique test to test the stereo speakers on Xiaomi flagships. 12/13/14 A series that is not in the standard instructions.

1. Quick check: exclude obvious causes

Before you dig deeper, make sure that the problem is not the trivial stuff. About 30% of service calls about a broken speaker are solved in 2 minutes.

• 🔈 Check the volume level: press the volume button up or open the Quick Settings panel. It's possible that the sound is just off or set to a minimum.
• 🎧 Turn off the headphones./Bluetooth-Devices: sometimes the smartphone forgets to switch back to the speaker after connecting accessories.Reboot the phone if the sound is not restored.
• 🛠️ Make sure there are no physical obstacles: inspect the speaker grille for dust, dirt or moisture. 11T/12 Pro speakers are located at the bottom and easily clogged.
• 🔕 Check the "Do Not Disturb" mode: go to Settings → Sound. → Do not disturb and make sure that the mode is turned off or configured correctly.

If you don't have the sound after you do this, you go to the next step, and if the speaker is working, but the sound is distorted (wheezing, crackling), the problem may be membrane damage or contact corrosion (relevant for phones that have been in the water).

⚠️ Note: On Xiaomi models with dual speakers (e.g. Redmi) K40/50, POCO F4) Check both speakers separately. Sometimes only one fails and the user thinks there's no sound at all.

2. Built-in sound tests: how to run a diagnostics on Xiaomi

All Xiaomi smartphones (starting with MIUI 10) have a hidden diagnostic menu where you can test speakers without third-party applications, which works even if there is no sound in the system – the test uses low-level access to hardware components.

To run the test:

1. Open the Phone app.
2. Enter the combination: ##4636### (on some models it may not work – see the alternative below).
3. Select Hardware Testing (or Hardware Testing).
4. Find the Audio or Speaker section and run the test.

If the combination does not work, try an alternative method:

Settings → About Phone → MIUI version (shap 7 times in a row until the message “You became a developer” appears)


Next: Settings → Additional → Developers → Diagnostics → Equipment Test

During the test, the speaker has to produce sounds of different frequencies, and if the sound is not heard or distorted, it's a hardware problem, and if the test is successful but there's no sound in the system, it's the software's fault.

3. Check through the engineering menu (for advanced users)

The Engineering Mode provides access to advanced tests of hardware components, including speakers, which is suitable for models running Qualcomm processors (most Xiaomi/Redmi/POCO).

Instructions:

1. Open the Phone app.
2. Enter the code ##36446337## (or #4636### on some models).
3. Choose Hardware Testing → Audio.
4. In the Speaker Test section, select the test type: Normal Mode – standard test; Loopback Mode – test with feedback (to check the microphone and speaker at the same time); Receiver Test – check the top (conversational) speaker.

In the engineering menu, you can also check the impedance speaker (resistance). Normal values for Xiaomi:

• 📱 Main speaker: 8-32 ohms;
• 🗣️ Speaking speaker: 16-100 ohms.

If the impedance is 0 ohms, the circuit break, if ∞, the short circuit, both cases need repair.

💡

On models with MediaTek (e.g. Redmi 9A/10A), the engineering menu opens with ##54298###.

4. Testing through third-party apps: top-3 utility for Xiaomi

If standard tests don't give a definitive answer, use specialized applications that allow you to check the dynamics in more detail, including distortion tests, frequency analysis and stereobalance comparison.

The best diagnostic applications:

• 🔊 Speaker Test (from Keuwlsoft) - tests speakers at different frequencies (20 Hz - 20 kHz), detects distortion.
• 🎛️ Audio Test – checks stereobalance, plays test signals (sinusoids, noise) Suitable for Xiaomi diagnostics with two speakers.
• 📊 Phone Check and Test – a comprehensive test of all components, including speakers, microphone and audio jack.

How to use:

1. Install the application and open it.
2. Choose a speaker test (Speaker Test or similar).
3. Follow the instructions on the screen. You usually need to confirm if you hear the sound.
4. Pay attention to the frequency response graph – dips at certain frequencies indicate damage to the speaker.

If the app shows that the speaker is working, but there is no sound in the system, the problem is in the audio driver or firmware. Try resetting the audio settings or reinstalling MIUI.

5. Physical Injury Check: What Can Be Done at Home

If the software tests didn't show any problems, but the sound is still missing or distorted, it's possible that the speaker is physically damaged.

• 🔍 Visual inspection: Take a flashlight and look at the speaker grille, and the presence of corrosion, dents, or ruptures in the membrane (seemingly as a dark spot) suggests that replacement is necessary.
• 💨 Pull: gently blow the speaker (you can use a can of compressed air). If the sound improved after that, the problem was the blockage.
• 🔊 Vibration test: Turn the music on at maximum volume and put your finger on the speaker grille. If there's vibration but no sound, the membrane is torn off the coil.
• 💧 Moisture test: if the phone fell into the water, even after drying, the contacts of the speaker could oxidize.

On Xiaomi models with dual speakers (e.g. Xiaomi 11T Pro, Redmi K50) check both speakers separately:

1. Turn on the music and alternately cover each speaker with your finger.
2. If the sound is lost when one of them is closed, the second speaker does not work.

⚠️ Attention: Don't try to disassemble the phone yourself if you don't have experience! On Xiaomi, speakers are often soldered to the motherboard, and careless handling can damage other components. The service charges from 800 to 2,500 rubles for replacing the speaker (depending on the model).

6.Diagnostics through ADB: for power users

If you are familiar with ADB (Android Debug Bridge), you can check the speaker at a low level bypassing the MIUI interface. This method is useful if the sound is missing due to a firmware failure.

Instructions:

1. Install ADB Tools on your PC.
2. Enable USB Debugging on your phone (Settings → About Phone → MIUI version (7 taps) → For developers → USB debugging).
3. Connect the phone to the PC and type in the command line:

adb shell


su




tinyplay /system/media/audio/alarms/Alarm_Classic.ogg

If the sound is played, it's a problem in MIUI (e.g., audio access rights are lost), and if it's not, the speaker or audio chip is faulty.

To check the conversational speaker, use the command:

tinyplay /system/media/audio/notifications/Piano_Trill.ogg --device 2

Where --device 2 It indicates a conversational speaker (some models may differ).

💡

If the tinyplay command returns the Unable to open device error, it means that the audio driver is not responding, and 90% of the time, flashing or resetting to factory settings helps.

7.Special cases: specifics of Xiaomi models

Some Xiaomi models have unique sound problems.

• 📱 Xiaomi Mi A1/A2/A3 (Android One: often lose sound after updates. The solution is a rollback to the previous version of the firmware.
• 🎵 Redmi Note 8/9 Pro: There are known cases of contact drops due to vibration.
• 🔊 POCO F1/F2/F3: Sound problems can be related to overheating of the processor. CPU Monitor.
• 💎 Xiaomi 12/13/14 Series: use Dolby Atmos technology, which sometimes resets settings. → Sound. → Sound quality and select the Profile Speaker.

For Xiaomi 13 Ultra and 14 Ultra with four speakers (two top and two bottom) use a special test:

adb shell am start -a android.intent.action.MAIN -n com.android.settings/.DeviceSoundSettings

This will open a hidden stereo audio setting menu where you can check each speaker separately.
