The situation when the smartphone displays connected headphones Xiaomi, but the sound continues to be broadcast through the speaker of the phone, is puzzling. the user sees the icon of the headset in the notification curtain, but the music or voice of the interlocutor is not heard. This is a common software glitch in the shell of MIUI or HyperOS, which is often solved without contacting the service center.
The reason may be the incorrect distribution of audio streams in the Android system, the phone “thinks” that the device is active, but does not redirect media content to it, sometimes it is the fault of the Bluetooth module freeze or conflict of connection profiles.
In this article, we will discuss step-by-step methods for fixing the bug: you will learn how to force switch audio output, clear the Bluetooth cache and perform a complete reset of the headset. Follow the instructions carefully to return full-fledged accessory work.
Diagnostics of current connection status
The first thing you need to know is how deeply the system has captured the device. It often happens that the headphones are only connected as a headset for calls, not as a media device. Check your Bluetooth settings by pressing and holding the gear icon next to the name of your Redmi Buds or Mi True Wireless model.
In the menu that opens, look at Profiles, where the audio and multimedia switches must be activated, and if one of them is turned off, the system will ignore the headset when you start YouTube or a player, a common mistake after updating the firmware.
- 🎧 Check if the battery level is displayed in the Bluetooth widget.
- 📱 Make sure that the output to the external device is selected in the sound settings.
- 🔊 Play the test track and look at the volume indicator.
It's also worth checking if the Monoaudio mode is activated or the balance isn't completely tilted to one side, which can create the illusion of a non-working device.
⚠️ Warning: If the Bluetooth listing labels the device as "Connected" but the sound is not coming, don't rush to remove it from your phone's memory. First, try just turning off and turning on Bluetooth in the curtain.
Sometimes it helps to just switch the audio output source through the notification curtain. Start the music, open the control panel and click on the speaker icon. In the list that appears, choose your headphones forcefully.
Basic actions for reloading modules
The most effective way to reset temporary communication errors is to completely reboot the wireless module. Don't just turn off Bluetooth. Go to Settings → Bluetooth and turn off the function completely.
Then put the headphones in the case and close the lid. Wait 10-15 seconds for the device to go into standby mode. Then activate Bluetooth again on the smartphone and pair, which helps in 60% of the cases of glitches.
If the problem persists, try restarting the smartphone itself. While the phone is turned off, the system clears RAM and closes background processes that could block the audio stream. After turning on the phone, take your time, give the system 2-3 minutes to load all services.
☑️ Quick reboot algorithm
There is also a hidden way to restart the Bluetooth service through the engineering menu, but it requires caution. For the average user, a standard system reboot is enough, which updates the driver configuration files.
Device removal and Bluetooth cache cleaning
If simple methods didn’t help, delete the saved profile of the device. Go to the list of paired gadgets, click on the gear icon or arrow next to the headphone name and select “Cancel pairing” or “Forget device”.
After that, it is critical to clear the Bluetooth cache on Android. Accumulated cache errors can prevent the connection from being properly initialized. Go to Settings → Applications → All Apps.
In the list, find the system process “Bluetooth” (sometimes called “Bluetooth MIDI” or “Bluetooth Sharing”). Click on it, select “Memory” and click “Clear.” Don’t worry, your personal files won’t be affected.
| Action. | Where to find out. | The result |
|---|---|---|
| Forget the device | Bluetooth settings | Removal of the communication profile |
| Clearing the cache | Annexes → Bluetooth | Resetting the module settings |
| Resetting network settings | Advanced settings | Complete reset of Wi-Fi and BT |
Once the cache is cleaned, search for the devices and pair them again, and now the connection will be established from scratch, without the old conflicting parameters.
What if the “Bluetooth” item is not in the list of applications?
Reset Xiaomi headphones to factory settings
When the software methods on the phone are exhausted, you need to reset the headphones themselves. Xiaomi and Redmi models have a different procedure. TWS-The models (True Wireless Stereo) need to place both headphones in the case.
An open case with headphones inside requires a functional button to be pressed (usually between compartments or on the back wall) and hold it for 10-15 seconds until the indicator lights up in orange or white (depending on the model).
- 🔴 The indicator flashes red - the process of resetting is underway.
- 🟢 The indicator caught fire white - reset successfully.
- 🔵 Indicator flashes blue - the pairing mode is activated.
For models with touch-controlled without a button on the case (for example, some versions of Mi AirDots), the procedure is more complicated: you need to pull out the headphones, then quickly press the touch areas of both earphones 5 times at the same time until they sound the reset signal.
⚠️ Attention: After reset, the headphones may stop synchronizing with each other (working in stereo). TWS-interface described in the instructions for a particular model.
Once reset, remove the device from the Bluetooth list on your phone and search again, which is guaranteed to eliminate the errors of the internal logic of the headset.
💡
When resetting headphones, make sure that the case is charged at least 30%. interruption of the reset process due to battery discharge can lead to the "bricking" of one of the headphones.
Set up audio codecs and developer
In rare cases, the problem is that the audio codecs are incompatible, the system may try to transmit sound in a format that the current connection does not support, and you can use the developer menu to diagnose it.
To activate the menu, go to Settings → About Phone and quickly click on MIUI 7 times. Then go back to the main settings menu, select “Additional” → “Developers.” Find the Bluetooth Audio section.
Try changing the codec from AAC or aptX to SBC. It's the basic codec that all devices support, and if you have sound after switching, then the problem was with the high-quality drivers.
Path to setup:
Settings → Additional → For Developers →
Bluetooth Audio Codec (Bluetooth Audio Codec)And there's also the option on this menu, "Disable absolute volume." Try to switch it, which will disconnect the volume control of the phone and the headphones, which sometimes solves the silence problem.
💡
Switching to the SBC base codec often returns sound if the problem is caused by a software conflict while transmitting high-resolution data.
Hardware malfunctions and maintenance
If none of the software methods worked, there is a high probability of hardware failure, which could be a failure of the Bluetooth module in the phone or damage to the antenna in the headphones themselves after falling or getting moisture.
Check the headphones with another smartphone (iPhone, Samsung or other Android) if another device has a recurring problem, it's the headset's fault. If it works, it's the Xiaomi module.
- 💧 Moisture entering the dynamic driver.
- 🔋 Battery degradation that does not give the desired voltage.
- 📡 Physical damage to the antenna inside the housing.
In case of detection of hardware fault self-repair TWS-Headphones are often inappropriate due to their monolithic design. it is recommended to contact an authorized service center for diagnosis.
