What to do if there is no sound on Xiaomi phone: from simple checks to complex repairs

Sound problems on Xiaomi smartphones are one of the most common problems faced by users of Redmi Note 12, POCO X5, Mi 11 and other lines. Symptom can manifest itself in various ways, from the complete absence of sound in the speakers to distortions when playing music or talking. The reasons range from trivial (accidentally pressed button) to serious (hardware board failure).

In this article, we'll look at all possible scenarios, from software failures to physical damage, and we'll give you quick checklists. If you're not a techie, don't worry: most solutions don't require disassembling your phone. For advanced users, we've prepared instructions using ADB and service codes.

⚠️ Warning: If the sound is gone after a phone drop or moisture, turn off the device immediately and do not turn it on until you visit the service center.

Basic checks: what to do first

Before you commit a breakdown, make sure that the problem is not the obvious, and 40 percent of the time, the sound is lost because of mechanical switches or system settings.

Start with the simplest:

• 🔊 Check the physical sound switch (if you have one on your model) on some Xiaomi (like Redmi). K50 Gaming) has a hardware slider for switching the "Call/Vibration/No Sound" modes".
• 🎧 Disconnect your headphones or Bluetooth devices. Sometimes the phone forgets to switch back to speakers. Try plugging and turning the headphones off several times.
• 🔄 Reboot your phone. The banal rebuke solves up to 20 percent of software failures associated with sound. Press the power button for 10 seconds if the phone doesn't respond.
• 📱 Check the volume level. Press the volume buttons up/down, the scale should appear on the screen. If it's not there, there may be a failure in the system interface.

If you don't get the sound after that, move on to the next section, and pay particular attention to the headphone item, because many users spend months looking for a solution, noticing that the phone simply doesn't recognize the 3.5mm jack being turned off.

System settings: Where to look for a problem

Software failures are the second most common cause of lack of sound. Xiaomi with the MIUI shell has several pitfalls that users are often unaware of.

Open the Settings → Sound and vibration and check:

• 🔇 "Don't disturb. Make sure the mode is turned off or set up correctly (e.g., don't check "No sound").
• 🎵 "Media and Calls. Move the volume sliders for each type of sound separately.
• 🔄 "Adaptive sound. Turn off this feature -- it sometimes misaligns volume depending on the ambient noise.
• 🎧 "Sound through speakers when you connect your headphones. If the option is on, the phone can confuse the output routes.

Also, look at Settings → Special Features → Hearing. This can activate features like Mono Audio or Sound Amplification that distort playback. If you don't use these options, turn them off.

3. Software glitches: resetting settings and updates

If the basic settings didn’t work, the problem could be a system failure, which on Xiaomi often happens after MIUI updates or installing third-party apps that conflict with the sound driver.

Remedies:

• 🔄 Reset the sound settings. Go to Settings. → System and device → Resetting settings → Reset the audio settings. It'll bring all the parameters back to factory without losing data.
• 📱 Clear the app cache. Go to Settings. → Annexes → Application management, find Media and Phone, then click Storage → Clear the cache.
• 🔧 Update MIUI. Check for updates in Settings → The phone. → System update. Sometimes the sound goes missing because of bugs in a particular firmware version.
• 🛠️ Retrace to factory settings. Extreme method: Settings → The phone. → Setting reset. Warning: this will delete all data from the phone!

If the problem occurs after installing a specific application (such as a player or messenger), try to remove it. Some programs (such as VLC or PowerAmp) may conflict with the Xiaomi sound stack.

⚠️ Warning: Before resetting to factory settings, save a backup through Settings → The phone. → Backup: Data recovery after reset is not always smooth, especially if the problem is partition damage. /data.

💡

If the sound is gone after the MIUI update, try to roll back to the previous version via Fastboot.Instructions for your model, look for the XDA Developers or 4PDA forum.

Hardware problems: speakers, connectors, microphones

If the software methods didn't work, it's probably the hardware.

• 🔊 Speaker (especially the lower one, which is used for music and calls).
• 🎧 3.5mm connector (if you have one on your model).
• 📞 Microphone (problems appear when calling: the interlocutor does not hear you).
• 🔌 The plumes connecting the motherboard with the speakers.

For diagnosis, follow the following steps:

To check the microphone, call another phone and record a voice message. If your voice is not being recorded or is being recorded with noise, the microphone is the problem. The speakers can be checked by turning on the recorder at maximum volume - if the sound is distorted or absent, repair is required.

5. Problems with Bluetooth and wireless devices

If the sound is only lost when connected to Bluetooth headphones, speakers or car radio, the problem lies in the wireless module. At Xiaomi, this is often due to:

• 🔄 Blutch in Bluetooth profile (for example, after updating) MIUI).
• 📱 Device-specific conflict (e.g. AirDots headphones are not compatible with your phone model).
• 🔋 Energy savings that shuts off Bluetooth module.

How to fix it:

1. Remove the problem device from the list of conjugates: Settings → Bluetooth, click on the gear next to the device and select Remove.
2. Turn off the power saving mode: Settings → Battery and performance → Energy saving mode.
3. Reset Bluetooth settings: Settings → System and device → Reset settings → Reset Bluetooth settings.
4. Update the firmware of the Bluetooth module (if available for your model).

If the problem persists, try connecting the headphones to another phone. If they work, it's your Xiaomi. If not, it's the headphones themselves.

💡

On Xiaomi models with Qualcomm Snapdragon chipset (such as POCO F5), Bluetooth crashes are often solved by flashing the module through Fastboot.

Advanced Diagnostics: Service Codes and ADB

For experienced users, there are diagnostic methods that do not require disassembling the phone, but give detailed information about the state of the hardware.

Service codes for sound verification:

• #4636## → Phone information → Check the status of the audio.
• #36446337## – Test of hardware components (not working on all models)
• ##0673## or #0289## is a test of microphone and speakers.

For a deeper diagnosis, use ADB (Android Debug Bridge) and connect your phone to your PC and follow the commands:

adb shell


su




dumpsys media.audio_flinger

This command will output the audio stack state. Look for error lines (ERROR or FAILED).

If you are not familiar with ADB, it is best to skip this section – the wrong commands can make the problem worse.

⚠️ Note: Service codes may vary depending on model and version MIUI. Some codes (for example, for a speaker test) trigger loud signals – be prepared to turn the volume down quickly.

7. When to contact the service center

If none of these methods worked, it's probably a hardware problem.

• 🔊 The speaker does not make any sounds, even after resetting the settings.
• 💦 The phone fell into the water or was subjected to a strong vibration.
• 🔥 On the motherboard, traces of oxidation or burning are visible (when disassembling).
• 📱 The problem appeared after an unofficial firmware or "overclocking" of the processor.

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

• Dynamic replacement: 1500–3000 ₽.
• Microphone Replacement: 1000–2500 ₽.
• Repair of plumes: 2000–5000 ₽.
• Replacement of audio codec (in case of chip damage): 5000–10,000 ₽.

Xiaomi’s official service centers offer a warranty for repairs, but prices are higher than in unofficial workshops. Before visiting, check if there are spare parts for your model – some components (for example, for the Redmi Note 8 Pro) may be in short supply.

💡

Before visiting the service, back up your data via Mi Cloud or Google Account. After repair, you may need to reset your phone.
