Xiaomi Sound Disappears: How to Return It in 10 Minutes (Instruction 2026)

You've played a video on the Xiaomi Redmi Note 12 or POCO X5 Pro, but instead of music, silence? Or do the calls come and you hear only vibration? Sound problems on Xiaomi smartphones are more common than you think: according to service centers, 12% of calls are related to audio. The good news is that 80% of the time, you can fix the malfunction yourself without resorting to expensive repairs.

In this article, we’ll look at all the possible causes, from the banal “Do Not Disturb” mode to damage to the audio codec, and give step-by-step instructions for restoring sound. Particular attention will be paid to models with Harman Kardon speakers (such as Xiaomi 13 Ultra), where problems are often associated with software conflicts. If after reading the sound does not return, you will at least know for sure whether the “firmware” is to blame or it’s time to bring the phone to the service.

So let's start with the simplest one: checking the physical elements, and you'll be surprised to learn that 30 percent of the time, the problem is solved by cleaning the speaker from dust or restarting the device.

1. Checking physical elements: speakers, connectors, buttons

Before you dig into the settings, make sure the problem isn't mechanical. Start by looking at the speakers and connectors.

• 🔍 Visual inspection: Light a flashlight into the speaker grille (usually at the bottom of the case). Do you see foreign objects, dust or moisture? On Xiaomi models 12T And newer speakers are often clogged with fibers from pockets.
• 🎧 Headphone test: Connect wired or wireless headphones, if there's sound in them, the problem is the smartphone speakers. If not, the malfunction could be in the audio track or firmware.
• 🔊 Microphone check: Record with voice memo. If the recording is silent or distorted, the problem may be in the microphone (relevant to the sound of the microphone). POCO F4 GT, where the microphone is located next to the speaker).

Pay special attention to the Type-C connector (or 3.5 mm if you have one), oxidizing contacts or getting moisture often leads to loss of sound in the headphones, wipe the connector with a cotton swab soaked in alcohol, and let it dry for 10 minutes.

💡

If you don't have a sound after cleaning the connector, try connecting the headphones to another device, and if they work, it's a problem with the smartphone, if not with the cable or the headphones themselves.

On models with stereo speakers (such as the Xiaomi 13 Pro), check both speakers separately. Hold your finger on one of them and play the sound – if it switches to the second, then the first speaker is faulty.

Programmatic diagnostics: sound settings and modes

If you're physically okay, we'll move on to the software part.

1. Volume level: Press the volume button up. A slider will appear on the screen to make sure it's not at zero. Some firmware (e.g. MIUI 14) have separate regulators for media, calls and alarms.
2. Do Not Disturb Mode: Swipe down from the top of the screen and check if the cross-over bell icon is activated. Also go to Settings → Sound and Vibration → Do not disturb and turn off the mode if it is on.
3. Sound Profile: In the same audio settings, select the General profile instead of Quiet or Meeting.

On models with MIUI 13 and older, there is a hidden mono-audio feature that can be activated by accident to turn it off:

1. Go to Settings → Special Opportunities → Hearing.
2. Find the Monoaudio item and turn it off.
3. Reset the device.

If the sound is gone after the firmware update, try resetting the sound settings to the factory.

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

3. Resetting settings and firmware update

If the basic methods didn't work, we'll take a more radical approach, starting with resetting all the settings (without deleting the data):

• 📱 Go to Settings. → The phone. → Resetting settings.
• 🔄 Select "Reset all settings" (not "Delete all data"!).
• ✅ Confirm and wait for the reboot.

This method helps in 40% of cases when the sound is lost after installing an application or changing system parameters.

To update the firmware:

1. Go to Settings → About the phone → System update.
2. Click "Check Updates."
3. If a new version is available, download it and install it.

💡

If the sound doesn't appear after the update, try installing the firmware manually via Recovery or Fastboot.Instructions for your model, look for the XDA Developers forum or 4PDA.

For models with MIUI 14 and later, there is an alternative way to upgrade through the Update app (an icon with an arrow in a circle), sometimes offering more recent builds than the standard settings.

4.Diagnostics through engineering menu and test codes

If the sound never comes, it’s time to use hidden diagnostic tools. All Xiaomi smartphones have an engineering menu that allows you to test speakers, microphone and audio track.

To get into the engineering menu:

1. Open the phone app.
2. Enter the code ##4636##.
3. Select "Phone Information" (or "Testing" on some models).
4. Scroll down to the Audio or Sound section.

In this menu you will see a few tests:

• 🔈 Speaker Test: Checking the top and bottom speakers.
• 🎤 Microphone Test: Microphone Test (talk to the microphone – signal level should be displayed).
• 🎧 Headset Test: Checking the sound in headphones.

If you have sound in the engineering menu and you don't have it in the system, it's the firmware or the settings, and if you don't have sound here, it's probably the audio codec that's in the wrong place.

For the Xiaomi 13/14 series and POCO F5 models, there is an additional test code: ##36446337##. It opens an extended diagnostic menu where you can check speaker impedance (resistance). Normal values are 32 Ohms ± 10%. If the performance is very different, the speaker is faulty.

5. Problems with Bluetooth and wireless headphones

If the sound is only lost when you connect to Bluetooth, the problem may be in the connection protocol or codecs.

• 🔗 Reconnect Device: Remove the headphones from the list of associated devices (Settings) → Bluetooth and reconnect.
• 🎵 Change the codec: In Bluetooth settings (near the headphone name) select the codec SBC instead AAC Or aptX. The latter is often glitched at MIUI 14.
• 🔄 Reset Bluetooth settings: Go to Settings → System and device → Resetting settings → Resetting Bluetooth settings.

On the Xiaomi 12S Ultra and POCO F4 GT models, there is a bug with a stuttering sound in wireless headphones.

1. Activate Developer Mode (7 times click on the MIUI version in your phone settings).
2. Go to Settings. → Additionally. → For developers.
3. Find the option “Disable Bluetooth absolute volume” and activate it.
4. Reboot the phone.

💡

If the sound is quieter after changing the codec, go back to AAC. This codec is better optimized for the balance of quality and volume on Xiaomi devices.

If the problem persists, try connecting the headphones to another device. If there is sound, it's the smartphone. If not, it's the headphones. On models with Qualcomm Snapdragon 8 Gen 2 (such as the Xiaomi 13 Pro), sometimes rolling back the Bluetooth driver via Fastboot helps.

6. Hardware malfunctions: when without service can not do

If all the software methods have been tried and there's still no sound, it's probably a hardware breakdown.

• 🔧 Damage to audio codec: Qualcomm chip WCD9385 (It's installed in most flagships, and it fails when it overheats or falls, and it's not sounding in the speakers or the headphones.
• 💧 Contact corrosion: Ingestion of moisture oxidizes the walkways on the motherboard, often found after "bathing" the phone or using in humid climates.
• 🔊 Dynamics break: On models with JBL-dynamics (e.g., dynamics, POCO F3 GT) Often departs contact drop dynamics from the fee.

It is not recommended to repair such breakdowns yourself - without a soldering station and experience, you can damage the fee, but there are a couple of checks you can do before you go to the service:

1. Speaker vertebrae: With the multimeter, check the resistance of the speakers (should be 8-32 ohms). If the device shows 0 or ∞, the speaker is faulty.
2. Visual inspection of the board: Carefully remove the back cover (on removable-covered models, such as the Redmi 9A) and inspect the board for burnt-out elements or traces of corrosion.

The cost of repair depends on the model:

Important: If the phone was in water, DO NOT turn it on and DO NOT plug it into charging! SIM-card and battery (if possible) and take to the service. Power wet device leads to short circuit and irreversible damage to the board.

7. Alternative solutions: if sound is needed urgently

While the phone is being repaired or you are waiting for parts, you can use the workarounds:

• 🎧 Bluetooth Column: Connect the external speaker via Bluetooth. Even if the main speakers don't work, the Bluetooth module often remains in good working order.
• 🔌 Type-C headphones: On Type-C models (e.g. Xiaomi 11 Lite), sound can be transmitted through the connector even if the audio codec is damaged.
• 📱 Outside USB-C DAC: Connect an external sound card (e.g. Xiaomi) USB-C Audio Adapter – It takes over the sound processing.

You can use the following for calls:

• 📞 Loud Communication: Turn it on when you call with a button in the call interface.
• 💬 Messengers: Call WhatsApp, Telegram or Viber – they use a separate audio channel.

If you need to listen to an audio file, upload it to the cloud (like Google Drive) and open it on another device. For models with MIUI 14, there is another lifehack:

1. Connect your phone to a Smart TV via Miracast (Settings → Connection and Sharing → Transfer to the Screen).
2. The sound will be transmitted to the TV wirelessly.

💡

External DACs and Bluetooth devices are a temporary solution, and if the audio codec is the problem, the sound will be through them, but the quality may deteriorate due to additional signal processing.
