You've played videos, played music, or tried to hear someone on the phone, but the Xiaomi Redmi speaker is silent? Sound problems on smartphones in this line are more common than you think. The reasons can be in both trivial settings and serious hardware failures. In this article, we'll look at all possible scenarios, from software bugs to physical breakdowns, and give step-by-step instructions for each situation.
It's important to understand that the diagnostic algorithm depends on which sound is missing, whether it's the lack of sound in the speaker during a conversation, the silence when playing media files, the problems with Bluetooth audio, or the complete absence of all the audio signals, and we structured the material so that you can quickly find a solution to your specific problem without unnecessary action and unnecessary manipulation.
If you are not sure about your technical skills, some methods (such as working with ADB or disassembling the case) are better left to the specialists. However, most of the reasons are eliminated in 5-10 minutes on their own - just follow our recommendations.
1. Checking basic sound settings
Before you sin on hardware malfunctions, make sure that the problem is not in the elementary settings. On Xiaomi Redmi, the sound can "disappear" due to randomly activated modes or lost parameters.
Start with a check:
- 🔊 Volume level: press the physical volume button up/down. A slider will appear on the screen to make sure it's not at zero. Sometimes users accidentally pinch the button in their pocket.
- 🔔 Do Not Disturb Mode: Swipe down from the top edge of the screen and check if the cross-out bell icon is active. Also go to Settings → Sound → Do Not Disturb and turn off the mode if it is on.
- 🎧 Connected devices: If you have Bluetooth headphones or a speaker connected to your smartphone, the sound can be automatically redirected to them. Open the notification panel and turn off all audio devices.
Pay special attention to the sound profiles. Redmi has separate settings for media, alarms and notifications. Go to Settings → Sound → Volume and check the sliders for each type of sound. If one of them is at zero, you just won't hear the corresponding signals.
⚠️ Warning: Some Redmi models (e.g. Redmi Note 10 Pro or Redmi 9T) have a bug that resets the volume settings for notifications after the MIUI update. If the sound is gone immediately after the update, hand back the sliders.
2. Reboot and reset sound settings
If the basic settings are fine but the sound is still not working, the next step is a software reboot, which helps in 30% of cases, especially if the problem is caused by a temporary system failure.
Follow the following steps:
- Press the power button for 10-15 seconds until the screen goes out and the phone starts to reboot.
- After you turn on, check the sound.
- If it does not help, perform a forced reboot: press the power button + increase the volume for 20 seconds (on some models, the combination may differ).
If the reboot didn't work, try resetting the sound to the factory.
- Go to Settings → System and device → Resetting.
- Select Resetting of sound settings (on some firmware, the item may be called Resetting of media settings).
- Confirm the action and restart the phone.
⚠️ Warning: On Redmi with custom firmware (e.g. Pixel Experience or LineageOS), resetting audio settings may result in loss of user uniforms in the player.
☑️ Diagnosis before reset
Problems with speakers: diagnosis and cleaning
If the sound is only missing from the external speaker (while talking or playing music), the problem can be mechanical. On Xiaomi Redmi, the speakers often get clogged with dust or fail after falls.
Perform a visual inspection:
- 🔍 Put a flashlight on the speaker grille (usually located on the bottom end of the phone) and if you see dust, dirt or foreign objects, you need to clean.
- 💧 Check if it's moisture, and even a small amount of water can cause the contacts to corrosion.
- 🔊 Try to play the sound at maximum volume. If you hear wheezing or distortion, the speaker is damaged.
To clean the speaker:
- Use a soft brush (for example, for drawing) or a toothpick wrapped in microfiber.
- Carefully remove visible dust without pressing the grille hard.
- To remove moisture, place the phone in a silica gel bag (out of a shoe box) for 12 to 24 hours.
If the speaker is physically damaged (for example, after a fall), it will cost 800-2000 rubles depending on the model. On the Redmi Note 12 Pro+ or Redmi K50, a dual speaker is used - when one module fails, the sound becomes quieter, but does not disappear completely.
| Model Redmi | Type of speaker | Cost of replacement (₽) | Frequent cause of breakdown |
|---|---|---|---|
| Redmi 10/10A | Single | 800–1200 | Dust, moisture |
| Redmi Note 11 Pro | Double (JBL) | 1500–2000 | Falls, mechanical damage |
| Redmi 9T/9A | Single | 700–1100 | Factory marriage (in early installments) |
| Redmi K60 | Double (Dolby Atmos) | 1800–2500 | Overheating, power booster failure |

4.Failures after the MIUI update: how to bring back sound
One of the most common reasons for loss of sound on Xiaomi Redmi is a bug in the MIUI updates, especially for MIUI 13/14 firmware, where sound drivers sometimes conflict with the core of the system.
If the sound is gone immediately after the update, try the following methods:
- 🔄 Reverse to the previous version MIUI: Download the old firmware from Xiaomi's official website (choose the version for your model!). Rename the file to update.zip and place it at the root of the phone's memory. Go to Settings → About Phone → System Update, click on three dots in the top right corner and select Select the firmware file.
Cleaning the cache of sound services
- Go to Settings → Applications → Application Management.
- Find Media Storage and Bluetooth, clear the cache and data.
- Reboot the phone.
Resetting all settings
Settings → System and device → Additional → Resetting settings → Resetting all settingsOn Redmi models with a Snapdragon 8 Gen 1/2 processor (such as the Redmi K50 Gaming) after upgrading to MIUI 14, sound may disappear from games due to a conflict with Dolby Atmos technology. Solution: disable Dolby in the audio settings or install a patch through Magisk (requires root rights).
1 Activate Developer Mode (7 once click on "MIUI Version" in "About Phone").
2. Go to Settings → Additional → For developers.
3. Find the item Turn off absolute volume and activate it.-->
5. Problems with Bluetooth and wireless sound
If the sound is absent only when connected to Bluetooth devices (earphones, speakers, car radio), the problem may lie in the connection protocols or codecs.
Diagnostics and solutions:
- 🔗 Check codec compatibility: Go to Settings → Connections and Sharing → Bluetooth. Click on the gear icon next to the connected device. Select the Audio Codec and try changing it from SBC to AAC or aptX (if supported).
Reset your Bluetooth settings
- Disable all associated devices.
- Go to Settings → System and Device → Resetting → Resetting Bluetooth settings.
- Reboot your phone and reconnect the device.
Update the firmware of the Bluetooth module
On some models (Redmi Note 11T Pro, Redmi K40) helps the firmware module through the Fastboot.
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot rebootThe NON-HLOS.bin file can be found in the archive with full firmware for your model.
If the problem persists, check if a third-party app (such as Bluetooth Auto Connect or SoundAssistant) is blocking the sound. Go to Settings → Applications and temporarily disable all programs related to the sound.
6. Hardware malfunctions: when without service can not do
If none of the software methods worked, it's probably a hardware problem, and here are the most common audio-related crashes on the Xiaomi Redmi:
| Symptoms. | Probable cause | Method of diagnosis | Decision |
|---|---|---|---|
| The sound is only in the headphones. | The audio chip connector or speaker plume is damaged | Call the contacts with a multimeter | Replacement of a plume or chip (2000–4000 ₽) |
| The sound is distorted, wheezing. | Dynamic membrane damaged. | Visual inspection, test sound | Replacement of speaker (800–2000 ₽) |
| The sound disappears when the phone is heated. | The tip of the contacts of the amplifier | Heating with a hairdryer (in service) | Chip soldering (3000–5000 ₽) |
| There is no sound in conversation, but there is in dynamics. | The upper speaker (conversational) is defective | Test call | Replacement of microphone+dynamics (1500–2500 ₽) |
On Redmi models with IP53 (such as the Redmi Note 12 Pro+), sound problems often arise from contact corrosion after moisture hits. Even if the phone hasn't sunk, high humidity can cause oxidation, requiring professional cleaning of the board in an ultrasonic bath.
⚠️ Warning: If you notice that the sound is gone after a phone drop or a heavy hit, don't try to disassemble it yourself. On an aluminum-bodyed Redmi (e.g., Redmi K60), there is a high risk of damage to the plumes when unprofessional disassembling.
💡
If the sound is lost periodically (i.e., not), the problem is likely to be poor contact of the speaker plume or amplifier, and in 80% of cases, soldering or replacing the plume helps.
7. Sound recovery via ADB (for advanced)
If you're sure the problem is software-based, but standard methods don't help, try resetting audio settings via ADB (Android Debug Bridge), which works on all Redmi models but requires a computer connection.
Instructions:
- Install ADB and Fastboot Tools on PC.
- Activate USB debugging on your phone: Settings → About Phone → MIUI Version (click 7 times) Settings → Additional → For Developers → Debugging on USB
- Connect the phone to a PC and execute the commands: adb shell su settings put global volume_music 15 settings put global volume_alarm 15 settings put global volume_notification 15 settings put global volume_system 15 settings put global volume_voice 15 reboot
If the sound does not appear after the commands are executed, try resetting the audio_policy settings:
adb shell
su
rm /data/vendor/audio_policy/*
rebootThese commands reset all sound policies to factory ones. Attention: some commands require root rights that may take away your warranty.
8. Alternative solutions: if nothing has worked
If you’ve tried all the techniques, but the sound on Xiaomi Redmi still doesn’t work, consider alternatives:
- 🔧 Use an external USB-C audio adapter (e.g. Xiaomi Type-C to 3.5mm). It bypasses the internal audio track and outputs the sound through an external DAC. Cost - from 500 rubles.
- 📱 Install custom firmware (e.g. Pixel Experience or LineageOS). XDA Developers has firmware with corrected sound drivers for most Redmi models.
- 🔄 Return your phone under warranty. If the device is warranty (usually 12 to 24 months) and the hardware problem is, contact the service center. Statistically, 60 percent of the sound faults on Redmi are warranty.
For Dolby Atmos-enabled Redmi models (like the Redmi K50 Pro), it sometimes helps to install the Dolby Digital Plus module via Magisk. Instructions can be found on thematic forums, but remember: this requires unlocking the bootloader and can lead to data loss.
1. Connect the phone to the tape recorder via USB.
2. Swipe down the notification panel.
3. Select USB Audio Transfer (USB Audio).
This bypasses the internal sound pathways and outputs the signal directly.-->
