Previous articleMissing sound on the Xiaomi phone: what to do if the speaker, headphones or microphone does not work

You have your own Xiaomi Redmi Note 12 or POCO X5 Pro to listen to music or to answer a call, and suddenly they found that the sound was gone, no music, no notifications, no voice, and the situation is familiar to many owners of Xiaomi smartphones, and the reasons can be very different, from accidentally pressing a button to a serious break in the speaker. In this article, we’ll look at all possible scenarios for why Xiaomi’s sound might disappear and give step-by-step recovery instructions – from the simplest checks to complex firmware manipulations.

It's important to understand that the sound problem isn't always hardware-related, and according to service center statistics, 60 percent of the time is due to software failures or incorrect settings. MIUI 14 Many users have encountered a bug when the sound in the headphones worked and the speaker didn't. Or the classic situation: you plugged in a Bluetooth headset and then forgot to turn it off in the settings, causing the sound to continue to go to a non-existent device. We will start with the most obvious reasons and gradually move on to more complex solutions.

If you're not sure about your technical skills, don't rush to disassemble your phone or install custom firmware. Many problems can be solved in two clicks. But if the sound is lost after a phone drop or moisture hits, this is an excuse to contact a service center. In this article, we will separately note cases where self-repair can aggravate the breakdown and deprive you of warranties.

1. Check basic settings: volume, Do Not Disturb mode and sound profiles

Start with the obvious -- check if the sound is off at the system level. MIUI There are a few places where you can accidentally turn off the sound or put the phone into silent mode, for example, the volume buttons on the sidebar can be clamped with a bag or a case, and the Do Not Disturb mode is activated on a schedule.

Open the swipe notification bar from top to bottom and notice the icons in the upper right corner:

• 🔔 Call with a sign of prohibition - Do not disturb or Quiet mode is enabled.
• 🎵 Wave speaker – sound is on, but media notifications may be disabled.
• 📳 Phone with waves – check the volume of calls separately from the media.

If there are no icons, go to Settings → Sound and vibration and check:

• 🔊 Slider Media Volume (for music, video, games).
• 📞 Slider Call volume (for calls and notifications).
• 🛑 Do not disturb tab – an automatic rule may be included (e.g. overnight).
• 🎧 Sound quality section – sometimes the equalizer settings are confused, which makes the sound barely audible.

Another common cause is a failure in the sound profile. MIUI There's a feature called Sound Profiles (not available on all models) where you can save different settings for your home, work or street, and if the profile is lost, the sound may disappear for individual applications:

1. Go to Settings → Sound and vibration → Sound profiles.
2. Select an active profile and click Reset.
3. Reboot the phone.

💡

If the sound is missing in only one app (for example, YouTube or Telegram), try clearing its cache in Settings. → Annexes → Application management → [name] → Warehouse → Clear the cache.

2. Problems with connected devices: Bluetooth, headphones, USB-C

One of the most insidious reasons for the loss of sound is the phantom connection of a Bluetooth device, for example, you plugged in Xiaomi AirDots wireless headphones and then turned them off without turning off the pairing in the phone, and the system continues to send sound to the headphones, even though they have long been discharged or out of range, as a result, nothing can be heard through the phone's speakers.

To check it out:

1. Open the notification bar and make sure the Bluetooth icon is not active (or click on it to turn it off).
2. Go to Settings → Connected devices → Bluetooth.
3. If there are connected devices in the list, click on the gear next to them and select Disable or Forget the device.

Another common situation is the pollution of the connector USB-C (Dust, moisture, or oxidation of the contacts can cause the phone to "think" that it has wired headphones connected to it, and turn off the built-in speakers to check this out:

• 🔍 Light a flashlight into the connector - if dirt or corrosion is visible, gently clean it with a toothpick with wool (not metal objects!).
• 🔌 Connect and turn off the headphones several times – sometimes it helps to “reset” recognition.
• 📱 Reboot your phone with connected headphones, then turn them off.

If you use USB-C-headphones or an adapter for 3.5 mm, make sure that:

• 🔌 Original or certified adapter (cheap Chinese adapters are often not recognized).
• 📦 The sound settings are on mode USB-audio (if there is such a point).
• 🔄 You have tried connecting your headphones to another port (for example, via a hub).

3. Software failures: reboot, reset sound settings, safe mode

If the basic settings didn't work, it's probably a software failure, and let's start with the simplest one, forced reset, and sometimes the sound driver freezes, and the usual shutdown/on doesn't help.

1. Press the power button for 10-15 seconds until the phone turns off (even if the screen goes out earlier).
2. Wait 30 seconds and turn it on again.

If the sound doesn't show up, try resetting the sound to the factory.

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

If there's a problem with the application conflict, Safe Mode will help, and it's only system applications that work in this mode, so if there's a sound, it's one of the apps you installed that's to blame.

• Press the power button until the shutdown menu appears.
• Press the button “Switch off” with your finger – a suggestion will appear to go to safe mode.
• Confirm and wait for the reboot.

Make sure the problem isn’t with the headphones.|Check the volume manually|Turn off Bluetooth.|Reboot the phone.|Try the safe mode.-->

If the sound is working in Safe Mode, find the app that is responsible:

1. Get back to normal.
2. Alternately remove newly installed apps (especially those that requested access to the microphone or speakers).
3. Check the sound after each removal.

⚠️ Note: If the sound is lost after the update MIUI, Don't rush to roll back to the old version. First, try clearing the system cache: Settings → Warehouse → Clean the cache. In 30 percent of cases, it solves the problem without losing data.

4. Factory reset: when it is needed and how to save data

If none of the previous methods worked, you may need a complete reset. This is an extreme measure, but it often helps with deep software failures, for example, after a failed update or custom firmware installation.

• 📱 Make a backup of the data through Settings → The phone. → Backup or Mi Cloud backup.
• 🔐 Remember or write down passwords from accounts (they will erase!).
• 📁 Transfer important files to your computer or cloud.

To reset the phone to factory settings:

1. Go to Settings → About the phone → Reset settings.
2. Choose to erase all data.
3. Enter your password (if required) and confirm the reset.
4. Wait until the phone is finished (it will reboot several times).

If the phone doesn’t respond to touch or doesn’t turn on, you can reset through Recovery mode:

1. Turn off the phone.
2. Press the power button + volume button until the Mi logo appears.
3. In the Recovery menu, select Wipe Data (manage volume buttons, confirm – power button).
4. After reset, select Reboot.

⚠️ Note: If you use Xiaomi with an unlocked bootloader or custom firmware (like LineageOS), a reset via Recovery can result in a knock (complete inoperability) of the phone.

5. Hardware malfunctions: how to diagnose and what to do

If the software methods didn't work, there might be a problem with the hardware, and here are the most common malfunctions.

• 🔊 Damage to the speaker - after falling or getting moisture.
• 🔌 Oxidation of contacts on the plume of the speaker or headphone connector.
• 📱 Separation of the plume – often occurs after repair or disassembly of the phone.
• 💧 Short circuit after liquid hit (even if the phone is turned on, the sound may disappear later).

To diagnose a hardware problem:

1. Check the sound in the headphones - if there is one, the problem is in the speaker or plume.
2. Call your phone from another device – if the person can’t hear you, the microphone is faulty.
3. Connect your phone to an external speaker via Bluetooth – if there is sound, the problem is in the phone’s hardware.
4. Shake the phone next to your ear – if you hear rustle or rattle, it may be that the speaker element has broken off inside.

If you suspect a hardware breakdown but are not sure, use the hardware test:

1. Type ##4636## (on some Xiaomi models it works ##6484##).
2. Choose Equipment Testing or Audio.
3. Run the speaker and microphone tests.

💡

If the phone falls or comes into contact with water, don’t try to disassemble it yourself – this can lead to loss of warranty.

If you decide to disassemble the phone yourself (for example, to clean the connector), consider:

• 🛠️ For Xiaomi will need a plastic spatula and suction cup – metal tools will damage the body.
• 🔋 Pre-discharge the battery to 20-30% - this will reduce the risk of short circuit.
• 📸 Take a picture of the location of the plumes before disconnecting - they are easy to confuse when Assembly.

6. Update firmware and rollback to the old version MIUI

Sometimes the sound disappears after the update. MIUI. For example, in MIUI 14 was a bug that made the sound in the calls quieter by 2-3 times, in which case either updating to the latest version or rolling back to the old one helps.

To update the firmware:

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

If the problem has occurred after the update, you can try to roll back.

1. Download the desired version of MIUI for your model from the official Xiaomi website.
2. Move the firmware file (.zip format) to the root folder of the phone.
3. Go to Settings. → The phone. → Updating the system → Three dots in the upper right corner → Select a firmware file.
4. Select the downloaded file and confirm the installation.

If you use custom firmware (e.g. Pixel Experience or LineageOS), the sound may be lost due to incompatibility of the kernel or drivers.

• Check on the forums (for example, 4PDA or XDA Developers, have other users experienced this problem.
• Try to reflash your phone to the official firmware through the Mi Flash Tool.
• Make sure the firmware is right for your model (e.g. Redmi Note 11 Pro and Redmi Note 11 Pro).+ have different sound drivers!).

7.Mic Problems: Why the Speaker Can't Hear You

If there's sound in the speakers, but the microphone doesn't work, the reasons may be different.

• 🎤 Try recording a voice message on Telegram or WhatsApp – if the recording is silent or missing, the microphone is faulty.
• 📱 Check if the microphone hole is covered with a cover or film.
• 🔊 Turn on speakerphone while calling – if the person hears you only in this mode, the problem is in the lower microphone.

Common causes of a broken microphone:

• 💦 Moisture entering the microphone (even a small amount can cause corrosion).
• 🔧 Damage to the plume after disassembling the phone.
• 📱 Software failure (for example, after installing an application requesting access to the microphone).

To fix the software problems with the microphone:

1. Go to Settings. → Annexes → Permits → Microphone and check which apps have access.
2. Disable access for suspicious applications.
3. Clear the cache and data of the Phone application (Settings) → Annexes → Application management → Phone. → Warehouse).

If the microphone doesn’t work in a particular app (like Zoom or Discord), try:

• 🔄 Reinstall the application.
• 📱 Give him permission to access the microphone manually.
• 🔊 In the application settings, select the correct input device (sometimes the default is a Bluetooth headset, although it does not exist).

8.When to contact the service center: signs of serious breakdowns

If you have tried all the methods, but the sound never appeared, you may need professional repairs.

• 💥 The phone fell from a height or was heavily hit.
• 💦 Moisture was getting in (even if the phone turned on, corrosion could damage contacts over time).
• 🔊 The sound is distorted (wheezing, crackling, interruptions) – this is a sign of damage to the speaker or amplifier.
• 📱 The phone doesn’t detect headphones or external speakers, although they are serviceable.
• 🔧 You took your phone apart and could have damaged the plumes.

The cost of repair depends on the model and type of breakdown:

Before the service visit:

• 📱 Backup your data (if the phone is turned on).
• 🔋 Charge your phone to at least 50% – some diagnostics require the device to be turned on.
• 📝 Write down when and how the sound disappears (after a drop, update, etc.) – this will help the wizard to find the cause faster.

⚠️ Note: If your Xiaomi is warranty, do not open it yourself and do not stitch custom firmware.This will void the warranty. Contact the official Xiaomi service center - repair warranty can be free.
