The lack of sound on Xiaomi devices is one of the most common problems faced by users of both smartphones and TVs of the brand. the reasons can range from a trivial error in settings to hardware malfunctions. In this article, we will discuss all possible ways to restore sound, from the simplest checks to complex technical solutions.
It's important to understand that the algorithm depends on the type of device: for smartphones (Redmi, POCO, Mi) and TVs (Mi TV, Redmi TV), the instructions will differ. We'll look at both cases, and we'll give you recommendations for diagnosing the problem. If the sound is lost after updating the firmware, dropping the device or connecting external accessories, here you will find a solution.
Before you start taking action, make sure that the problem is not due to external factors: check the connected headphones, speakers or sound bar. Sometimes the sound is simply redirected to another output device and the user does not notice it.
Basic check: sound and volume settings
The first thing you need to do is make sure that the sound isn't software-enabled, and on Xiaomi smartphones, you can check this in a number of ways:
- 🔊 Volume buttons: Press the physical volume/volume buttons on the sidebar. A slider will appear on the screen — if it's at zero, move it to the right.
- 📱 Notification panel: swipe down from top to bottom to open the curtain. Find the speaker icon and make sure it's not crossed out.
- 🔧 Sound settings: go to Settings → Sound and vibration. Check if no sound or vibration is activated.
On Mi TVs, the algorithm is similar:
- Press the Menu button on the remote.
- Select Settings → Sound.
- Make sure the volume slider is not at a minimum and the Mute mode is deactivated.
⚠️ Note: Some Xiaomi models (such as the Mi 11 or Redmi Note 10) have a Do Not Disturb feature that can automatically turn off notification sounds. → Notifications → Don't disturb.
If you don't have a sound after this manipulation, move on to the next section, and maybe there's a deeper problem.
2. Check connected devices and Bluetooth
Often, the sound disappears because the system automatically redirects it to a connected headphone, speaker, or other device, which is true for both Xiaomi smartphones and TVs.
On a smartphone:
- 🎧 Turn off all wired headphones (including Type-C adapters).
- 📶 Go to Settings. → Connected devices → Bluetooth and disable all associated gadgets.
- 🔄 Restart your phone – sometimes the system “forgets” to return the sound to the speakers after turning off the headphones.
On TV:
- 🔌 Check the ports. HDMI ARC, Optical or 3.5mm – possibly connected to sound system.
- 📺 Settings menu → Sound. → Output Sound Select Built-in speakers.
- 🔄 If you use a Bluetooth column, turn it off in Settings. → Bluetooth.
| The device | Problem. | Decision |
|---|---|---|
| Smartphone | The sound goes into the headphones, although they are turned off. | Clean the dust connector, reboot the phone |
| Television | No sound when connected via HDMI | Select the right sound source in Settings → Sound → Sound output |
| Laptop | Sound disappears after sleep | Update your audio drivers via Mi PC Suite |
⚠️ Note: On Xiaomi TVs with HDMI ARC So the sound can be automatically redirected to the sound bar or the receiver, and if the panel is turned off, the TV is silent, too.
3. Resetting the sound settings to factory
If the basic methods didn't work, the next step is to reset the audio settings, which doesn't affect personal data, but it will return all the sound parameters to the default state.
For smartphones:
- Open Settings → System and device → Additional → Resetting.
- Select Reset audio settings (on some models, the item may be called Reset media settings).
- Confirm the action and restart the device.
For TVs:
- Go to Settings → System → Reset and Update.
- Select Reset sound settings.
- Confirm and wait for the reboot.
On Xiaomi TVs, after resetting the audio settings, you may need to reset the equalizer and channel balance. That's okay - just return the preferred settings manually.
Make sure the sound is not physically switched off.
Turn off all Bluetooth devices
Close applications that use sound (YouTube, music)

4. Update of firmware and drivers
The lack of sound can be due to software bugs that are patched in new firmware versions, especially after major MIUI or Android TV updates.
For smartphones:
- 📱 Go to Settings. → The phone. → Updating the system.
- 🔍 Click Check Updates and install available patches.
- 🔄 After the update, restart the device.
For TVs:
- 📺 Open the Settings. → On TV. → Updating the system.
- 🔍 Select Check Updates and wait for the process to complete.
- ⚠️ If the update is interrupted, the TV may stop turning on – don’t turn it off during the process!
If the sound is gone after the update, try rolling back to the previous firmware version (if backup is available) or wait for the next patch. Xiaomi forums often post temporary solutions for such bugs.

5. Diagnostics of hardware malfunctions
If the software methods didn't work, the problem could be the hardware, like a damaged speaker, a broken plume, or a faulty audio chip.
For smartphones:
- 🔊 Speaker test: call the phone from another device, if the person you're talking to can hear you and you're not, the problem is the top speaker, if you can't hear anything, the bottom speaker or audio chip is faulty.
- 🎵 Connect headphones: if there is sound in them, but there is no speaker – the problem is in the speakers.
- 🛠️ Visual inspection: check whether the battery is swelling (can press the speaker plume), whether there are traces of oxidation on the connectors.
For TVs:
- 🔊 Speaker check: hold your ear to the back of the TV when the sound is on. If you hear a quiet crackle or noise, the speakers are working, but the sound is weak (maybe the problem is in the amplifier).
- 🔌 Test HDMI-port: connect the TV to another signal source (e.g., a set-top box) if there is sound, a problem with the previous device.
- 🛠️ Train check: if the TV fell, the plume connecting the motherboard to the audio module could move away.
⚠️ Warning: If you suspect a hardware malfunction, don't try to disassemble the device yourself - this could lead to a loss of warranty. Contact Xiaomi Service Center with a check to buy.
💡
Before visiting the service center, back up your data via Settings → Additional → Backup. This will save your photos, contacts and settings, even if the device has to be reset.
6. Alternative methods of sound recovery
If the standard methods didn’t work, try these non-obvious solutions:
- 🔄 Resetting to factory settings: a radical method that will delete all data but often solve software problems!
- 🔧 Disable Dolby Atmos: on some Xiaomi models (e.g. Mi 10 or Redmi) K40) The sound may be lost due to conflict with Dolby Atmos technology. → Sound. → Sound quality.
- 📱 Safe Mode: Load your smartphone in Safe Mode (hold the off button) → Safe Mode. If sound appears, a problem in one of the installed applications.
- 🔊 Outside USB-Sound adapter: for TVs Mi TV can be used USB-sound card (connected to the port) USB-A). This is a temporary solution if the built-in speakers don't work.
On TVs, you should also check the Digital Sound settings (SPDIF):
- Go to Settings → Sound → additionally.
- Find SPDIF format and select PCM over Auto or Dolby Digital.
- Save the settings and check the sound.
💡
If the sound is only missing from a particular app (like Netflix or YouTube), the problem is most likely in the app itself.
7. Frequent User Errors and How to Avoid Them
Many of the problems with sound are caused by the unobvious actions of users, and here are the most common mistakes:
- 🔕 Activation of In-Air mode: This mode shuts down all wireless modules, including Bluetooth, which can affect the sound.
- 🎧 Forgotten headphones in the connector: Even if the headphones are not connected, debris or moisture in the connector can create a false alarm of the sensor!).
- 🔊 Disabled system sounds: in Settings → Sound. → Additionally, the slider System sounds or Media can be disabled.
- 📱 Energy-saving mode: on some models (POCO X3, Redmi 9: Aggressive power saving settings can turn off sound to save charge.
A common mistake on Xiaomi TVs is choosing the wrong sound source, for example, if you watch IPTV through an app and the sound is set to output via HDMI ARC, it won't happen. Always check if the sound source matches the video source.
