Why the sound on Xiaomi phone doesn’t work: a full analysis of the causes and solutions

You pick up your Xiaomi to listen to music, watch a video, or answer a call -- but instead of the expected sound, silence. Or worse, you hear only distorted interference, crackling, and the speakers work every time. Is the situation familiar? Sound problems on Redmi smartphones, POCO or Mi flagships are more common than you think, and if you think that it's just a hardware defect, you're wrong 80 percent of the time.

In this article, we will examine all the possible reasons why the sound was lost on Xiaomi, from the banal volume settings to hidden failures in the MIUI firmware. You will learn how to diagnose the problem yourself, which software and hardware solutions work best, and when exactly to carry the phone to the service. And also unique life hacks for models with dual speakers (for example, Xiaomi 13 Ultra or POCO F5), where the sound can “disappear” due to the specifics of the design.

Don't rush to drop your phone to factory settings or spend money on repairs. 9 out of 10 times, sound is restored in 5 to 15 minutes -- if you know where to dig. Let's start with the simplest and get to the hardest cases.

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

The first thing to do is to eliminate the human factor, and most often, Xiaomi loses its sound due to randomly changed settings or activated modes.

• 🔊 Check the physical volume buttons. Press Volume up, you're going to see a scale with the sound level on the screen. If the scale is gray or crossed out, the sound is switched off.
• 🔔 The “Do Not Disturb” mode» (DND). Swipe down from the top of the screen to open the notification bar. If the bell icon is crossed, tap it to turn off mode.
• 🎵 Sound profile, some firmware MIUI There are separate profiles for Work, Home or Outdoors. Go to Settings → Sound and vibration → Sound profiles and select "Regular».
• 🔇 Turn off the sound for specific applications. Go to Settings → Annexes → App management, select the right one (such as YouTube or Spotify) and check the permission to play the sound.

Pay special attention to the No Sound mode, which can be activated automatically on a schedule, for example, if you once set up a quiet mode for the night and now forgot about it.

1. Open Settings → Sound and vibration → Do not disturb.
2. Check out the “Schedule” section – if there are ticks, remove them.
3. Make sure the switch is “Automatically” off.

If you've had a sound after this manipulation, the problem is solved. If you haven't, we'll move on.

2. Software failures: reboot, cache and reset sound settings

If the basic settings are fine, but the sound on Xiaomi is still not working, the fault of the software failure.

• 🐞 The mediaserver jammed process (responsible for sound reproduction).
• 🗑️ Cache of system applications related to sound.
• 🔄 Conflict after update MIUI or.

Start with the simplest thing, forced reboot, press the power button for 10 to 15 seconds until the phone turns off and turns on again, which helps in 30% of cases when the sound is lost due to a temporary failure.

If the reboot didn’t help, clear the cache of system applications:

1. Go to Settings → Applications → Application Management.
2. In the search, type Media and select Media Storage (or Android Media Provider).
3. Click on “Clear Cache” (not data!).
4. Repeat the same for Bluetooth, Phone and Google Play Music apps (if installed).

For Xiaomi models on MIUI 12-14, there is another effective way to reset the audio settings to the factory, which will not delete your data, but will return all the sound parameters to default:

##36446337## (enter the phone as a number in the appendix)


or


#3644633## (for older versions of MIUI)

Once you enter, you will open a hardware testing menu. Select Audio → Volume and press Restore Default. If you don't, your model doesn't support reset.

3.Discussions with speakers: how to check and clean

If the sound is only missing in the speakers (on headphones or Bluetooth everything works), the problem is probably hardware. But don't rush to bring the phone to the service - first perform the diagnosis:

How to check the speakers on Xiaomi:

1. Connect headphones – if there is sound in them, and there is no speaker, the problem is in the hardware.
2. Call your phone from another device, and if you have sound while you're calling, but you don't have system sounds, that's the settings.
3. Run the hardware test: Enter the code ##4636## in the Phone app. Select Audio Information → Audio Test. Listen to the test sounds for each speaker (top and bottom, if there are two).

If the test shows that the speaker is not working, the reasons may be as follows:

For dual speakers (e.g., Xiaomi 12 Pro, POCO X5 Pro), there is a nuance: often only the top speaker (which is responsible for high frequencies) fails. You can check this by covering the bottom speaker with your finger while playing music — if the sound is gone, the problem is in the bottom. If the sound is deaf, the top speaker is to blame.

Bluetooth and headphone problems: why the sound goes “wrong”

One of the most common causes of sound loss is a conflict with Bluetooth devices, and MIUI sometimes forgets to switch back to speakers after switching off the headphones or speakers. Here's how to fix it:

• 🎧 Forced Bluetooth shutdown. Open the notification panel, hold the Bluetooth icon and press "Disable." Wait 10 seconds and turn it on again.
• 🔄 Reset Bluetooth settings. Go to Settings → Connected devices → Bluetooth, click on the three dots in the upper right corner and select Reset Settings».
• 📱 Clearing the Bluetooth cache. → Annexes → App management find Bluetooth, click “Clear Cache” and “Clear Data».
• 🔗 Turn off automatic connection. In Bluetooth settings, find the problem device, tap on it and turn off the Auto Connection option».

If the audio is still going to the headphones, even though they are turned off, try restarting the media service:

1. Activate Developer Mode (if not activated): Settings → About Phone → MIUI version (shap 7 times).
2. Back to Settings → Additionally. → For developers.
3. Find the option “Disable Bluetooth Absolute Volume” and turn it on.
4. Reboot the phone.

Another trick for the POCO and Redmi models with MIUI 13+ is that if the sound is stuck in Bluetooth, try plugging any wired headphones into a USB-C connector (if it supports audio) and then turning them off, the sound should return to the speakers.

💡

If your Xiaomi doesn’t see the headphones after the MIUI update, try removing them from the list of associated devices, rebooting the phone and reconnecting them, often solving the problem with invisible gadgets.

5.Failures after MIUI Update: Recoil and Recovery

MIUI updates often bring new features, but sometimes break the sound. If a problem occurs immediately after the update, here's what to do:

Method 1: Reverse update (if available)

Some versions of MIUI allow you to return your previous firmware via Settings → About Phone → System Update. Click on the three dots in the upper right corner and select Update Package. If there is a rollback option, use it.

Method 2: Cleaning the System Update application data

1. Go to Settings → Applications → Application Management.
2. Find the System Update (or Updater).
3. Click on Clear Data (not just cache!).
4. Restart the phone and check the sound.

Method 3: Manual flashing through Fastboot (for advanced users)

If the sound is gone after a major upgrade (e.g. from MIUI 13 to MIUI 14), a clean firmware installation may help.

1. Download the official firmware for your model (choose the Fastboot version).
2. Install the Mi Flash Tool on your PC.
3. Connect your phone in Fastboot mode (clamp Volume down + Power when the phone is off).
4. In the Mi Flash Tool, select the downloaded firmware and click "Flash".

⚠️ Attention: Fastboot flashing will delete all data from your phone. pre-backup through Settings → Additionally. → Backup and reset.

💡

If the sound is gone after an update, never reset your phone to factory settings via the Recovery menu, which can make the problem worse if the failure is related to system libraries.

6. Hardware malfunctions: when without service can not do

If all the software methods have been tried, but the sound on Xiaomi still doesn't work, the problem is hardware.

• 🔧 The sound disappears when you press the body (for example, if you press the bottom of the phone) – the speaker plume has detached.
• 💧 The phone fell into the water or was exposed to humidity - contacts oxidized or the audio codec failed.
• 🔥 Before the sound disappeared, the phone overheated - the sound amplifier could burn out.
• 🔊 The speaker emits cracking or hissing even when the sound is turned off - the membrane or audio circuit is damaged.

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

For Xiaomi models with a frameless design (for example, Mi 11, Redmi Note 12), the repair of speakers is more expensive because of the complexity of disassembly. If the phone is warranty, do not open it yourself, otherwise the warranty will burn.

⚠️ Warning: If you're fixing your phone yourself, remember: Xiaomi speakers are often glued to double-sided tape and are attached with fragile latches. If you disassemble the phone carelessly, you can damage the screen plume or battery.

7. Specific problems for different Xiaomi models

Some Xiaomi models have unique sound problems related to their design or firmware.

📱 Redmi Note 10/11 series:

• Problem: After upgrading to MIUI 13, the sound in the speakers disappears, but it works in the headphones.
• Solution: Turn off the function “Smart amplification of sound Settings → Sound and vibration → Sound quality”.

📱 POCO F3/F4/F5:

• Problem: The sound is distorted at high volume (wheezing, crackling).
• Solution: Set the volume limit to 80% or turn off Dolby Atmos in the sound settings.

📱 Xiaomi 12/13 Pro:

• Problem: The upper speaker is not working (responsible for high frequencies).
• Solution: Check the Dolby Atmos settings - sometimes the stereo balance is strayed to "Left" or "Right."

📱 Redmi 9/9A/9C:

• Problem: The sound disappears after you connect to the charger.
• Solution: Clean the USB-C connector of dust (use a wooden toothpick) or replace the cable.

For models with an infrared port (e.g., Redmi Note 8 Pro, Mi 10), sometimes the sound “deafens” due to a conflict with the remote control. If you use the phone as a remote, try turning off the infrared port in Settings → Connected devices → Infrared port.

8. Alternative solutions: if nothing has worked

If you’ve tried everything, but the sound on Xiaomi has never worked, there are some radical or non-obvious methods:

• 🔄 Reset all settings (without deleting data): Go to Settings → Additionally. → Setting reset. Select "Reset all settings" (not "Reset to factory!"). Confirm action.
