Previous articleMissing sound on Xiaomi phone: why it happened and how to return the sound

Did you play your favorite track, but you can't hear a sound from Xiaomi speakers? Or does the person in the phone complain that they can't hear your voice, POCO Mi is more common than you think, and the causes can be in both trivial settings and serious hardware malfunctions. This article will help you separate software failures from physical failures without going to the service center, saving time and money.

We have analyzed hundreds of cases on forums. 4PDA, Mi Community and service centers to check the most likely causes, from the disabled mode "Do not disturb" to oxidized contacts on the motherboard. MIUI, And if you're not a techie, you don't see it on Android, and you give us diagnostic instructions with hidden engineering menus, and if you're not a techie, don't worry, all of the solutions are detailed, with illustrations and video links.

1. Software failures: when firmware or settings are to blame

In 60 percent of cases, the loss of sound on Xiaomi is due to software errors, not hardware failure. The first thing to do is check the basic settings and restart the device.

• 📱 Updates MIUI (especially beta)
• 🔊 Bluetooth headphone connections (the system forgets to switch back to speakers)
• 🎵 Using applications to change sound (ViPER4Android, Dolby Atmos)
• 🔋 Battery discharge up to 0% (audio driver configuration may be lost)

Start with the simplest:

1. Make sure the volume is not dimmed to zero (press the physical volume button up).
2. Check the Settings. → Sound and vibration → Do not disturb – it is possible that the mode “Quiet” or “Alarms only” is turned on".
3. Turn off Bluetooth in the notification panel – sometimes the system continues to send sound to non-existent headphones.
4. Reboot the phone with a long hold on the power button (10-15 seconds).

If the sound is lost after the update MIUI, Try to revert to the previous version through Settings → The phone. → Updating the system → Three dots (menu) → Select the service pack. To do this, download the stable firmware from the official Xiaomi website in advance (section "Download"). Attention: rollbacks can lead to data loss if you do not backup!

💡

On some models (for example, Redmi Note 10 Pro) after upgrading to the MIUI 14 lost sound in calls. Solution: Enable developer mode (Settings) → The phone. → Version. MIUI — Press 7 times and in the developer menu, turn off the option "Disable audio effects".

2.Resetting the sound settings: when the system "deafens" on its own

Operating system MIUI It is known for its ability to reset user audio settings after updates or reboots:

• 🔇 There is sound in the headphones, but not in the speakers
• 📞 The interviewer cannot hear you during the call (the microphone is not working)
• 🎮 The sounds in games are played, but on YouTube they are not.

The problem is most likely in the lost parameters of the audio system.

You can recover the sound through the hidden engineering menu:

1. Open the Phone app and type in the combination: ##36446337## (for new models) or ##4636## (for older models).
2. Select the Hardware Testing option → Audio.
3. Pass the tests Loud Speaker (speaker), Receiver (speaker), Microphone (microphone).
4. If the tests fail, click Restore Default.

Enter the code ##36446337##

Check all audio tests

Reset the sound settings to factory

Reboot the phone-->

Important: On some models (POCO F3, Xiaomi 11T) The engineering menu may not be available, and a full resetting (but remember to back up!) will help:

1. Go to Settings → About Phone → Backup and Reset → Reset settings.
2. Choose to erase all data.
3. After the reboot, check the sound before recovering data from the backup.

Hardware problems: speakers, connectors and microphones

If the software methods didn't work, it's time to check the hardware.

For self-diagnosis:

1. Check the speakers for physical damage: Hold the phone to your ear and see if there are any wheezing or distortions when playing the test sound (you can use the Speaker Test app).
2. Clean the connectors: Take a toothpick (not metal!) and gently remove dust from 3.5mm or USB-C For wet cleaning, use isopropyl alcohol 90%+ and cotton swab.
3. Check the microphone: record a voice memo or call another phone, and if the sound is intermittent or absent, the microphone or audio track is a problem.

💡

If the sound disappears when vibrating (for example, while walking), this is a sign of detachment of the plume speaker - it is necessary to disassemble and solder in the service center.

On the Redmi Note models 8/9/10 A common problem is that the bottom speaker is falling off because of weak soldering of contacts. If you press the bottom of the body, a sound appears, this confirms the diagnosis.

4. Moisture infestation: how to save the phone, if it "floated"

Even if your Xiaomi has protection by standard IP53 (Like the Redmi Note 11, it doesn't guarantee 100% moisture protection. Water or condensation is one of the main causes of sound loss":

• 💧 The sound appears and disappears when the phone changes position.
• 🔊 In the speakers you can hear gurgling or wheezing.
• 📱 On the screen there is a warning about moisture in the connector (on models with a USB-C)

If your phone is less than 30 minutes old:

1. Turn it off immediately and remove it. SIM-memory-card.
2. Wet with a dry napkin all visible drops (do not rub!).
3. Place your phone in a silica gel container (shoe box bags) on 24-48 Don't use rice, it leaves dust and is not effective!
4. After a day, check the sound, not turning on the phone - connect the charging and listen to whether there is a charging signal.

💡

To accelerate drying, you can use a fan at minimum speed, directed at the phone from a distance of 30 cm The main thing is not to overheat the device!

If more than a day has passed or the phone has already been turned on:

• 🛠️ Take the phone apart (if you have experience) and clean the board, speakers and connectors with alcohol. Pay special attention to the audio codec (chip next to the processor).
• 🔧 Check for contact oxidation -- green plaque on board tracks, and you can remove it with a pinworm or a special contact cleaning fluid.
• 📲 If the sound is partially restored, but there are wheezing – the speaker will have to be replaced.

⚠️ Warning: Do not turn on your phone if the screen displays a moisture warning in the USB-This can lead to a short circuit. Wait for the indicator to disappear (usually) 1-3 hour).

5. Application conflicts: When third-party programs are to blame

Some applications can block sound at the system level, and most often, the fault is:

• 🎵 Applications for uniform sound (ViPER4Android, Dolby Atmos, Equalizer FX)
• 🔒 Antivirus and Optimizers (Clean Master, 360 Security)
• 🎮 Game emulators (PPSSPP, ePSXe)
• 📱 Launchers from third-party developers (Nova Launcher, Apex Launcher)

To identify the "culprit":

1. Load your phone in Safe Mode (hold the power button) → long tap on "Switch off" → "Safe Mode. If sound appears, a problem in one of the installed applications.
2. Remove suspicious programs, starting with the last ones installed.
3. Check the application permissions in Settings → Apps → Permissions → Microphone/Sound.

Pay special attention ViPER4Android — This app often conflicts with audio drivers. MIUI. If you used it:

1. Open up. ViPER4Android And reset all settings to factory.
2. Turn off sound processing in Settings → Effects. → Turn on ViPER4Android.
3. Remove the driver through Settings → Annexes → ViPER4Android → Remove updates.

Another common problem is the blocking of sound advertising SDK If the sound is only lost in a particular app, try it:

• Clear the application cache in Settings → Annexes → [Name of game] → Memory. → Clear the cache.
• Turn off sound effects in the game settings.
• Install the patch through Lucky Patcher (at your own risk!).

6. Problems after firmware or unlocking the bootloader

If you're recent:

• 📲 Install custom firmware (LineageOS, Pixel Experience)
• 🔓 Unlocked the bootloader via Mi Unlock Tool
• 🔄 We've moved back to an older version. MIUI

The problem with sound is almost guaranteed to be due to the absence or incompatibility of audio drivers.

Decisions:

1. For custom firmware: Make sure the firmware supports your model (check on the forum) XDA Install a separate Audio Mod package (e.g. Magisk Module: Audio Compatibility Patch). MIUI via Mi Flash Tool.
2. For unlocked bootloader: Frisk your phone through fastboot with a clean all check the integrity of the firmware file (MD5-The hash must match the official hash).
3. To kick back on the old one. MIUI: Use OrangeFox Recovery or TWRP for a clean installation. /data/vendor/qti before the firmware (through ADB Sideload).

Commands to check audio drivers through ADB:

adb shell dumpsys media.audio_flinger


adb shell ls /vendor/lib/hw/ | grep audio

If the output commands do not have audio.primary.{corresponding chipset}.so files, then the drivers are not installed. The solution is to flash the phone again with the correct version of the firmware.

⚠️ Note: On models with a MediaTek processor (e.g. Redmi) 9A, POCO M3) If you fail to firmware, not only can you lose sound, but you can also lose communication, and then you can only flash it through the back door. SP Flash Tool with an Authorized Account.

7.When to contact the service: signs of serious breakdowns

If you've tried all the methods and the sound never came, it may be a hardware fault that you can't fix yourself.

• 🔊 The speaker emits cracking or hissing even in silent mode.
• 📱 Phone does not identify headphones (no icon appears in the status bar)
• 🔋 The sound is lost when the phone is heated (for example, during a game)
• 🛠️ On the board, traces of oxidation or bloated capacitors are visible.
• 🎛️ Engineering menu reveals Audio error IC Failed

Average repair prices in official Xiaomi services (2026):

Before the service visit:

1. Make a full backup through Mi Cloud or Google Account.
2. Delete your personal data if the phone remains in service.
3. Check whether the workshop uses original spare parts (the official details have the Xiaomi logo and serial number).
