You turned on music on the Xiaomi Redmi Note 12 or POCO X5 Pro, but the sound suddenly disappeared β and in the status bar is the icon of the headphones? Or the smartphone stubbornly switches the audio output to a non-existent headset, even though you have long disabled it? This error occurs on most Xiaomi models, from the budget Redmi 10A to the flagship Mi 13 Ultra, and it is associated with hardware or software failures in the audio system.
The cause may be a contaminated 3.5mm connector (if your model has one), a malfunctioning Bluetooth module, or even a damaged motherboard plume. In 80% of cases, you can solve the problem yourself without visiting a service center. In this article, we will examine all possible ways, from basic (reboot, clean the connector) to advanced (reset settings, diagnose via ADB).
Why does Xiaomiβs phone βseeβ headphones that donβt exist?
Falsely triggering the headphone connection sensor is one of the most common problems on Xiaomi smartphones, and it most often occurs for the following reasons:
- π Pollution or oxidation of the 3.5 mm connector β dust, moisture or corrosion close the contacts, simulating the connection of the headset.
- π± Failure of the audio driver - after the update MIUI or custom firmware installation driver may incorrectly determine the connector state.
- π Sticking Bluetooth contacts β if you previously used wireless headphones, the system could βforgetβ to turn them off.
- π οΈ Damage to the plume or motherboard β after falling or getting moisture, an audio track or connection controller may suffer.
- π€ Settings error MIUI β For example, activated mode "For developers" with enabled debugging USB Sometimes it conflicts with the audio system.
On models without a 3.5 mm connector (such as the Xiaomi 12T or Mi 11 Lite), the problem is almost always related to Bluetooth or software failures. But on devices with a physical connector (such as the Redmi Note 11 or the POCO M4 Pro), it is usually this one who is to blame. To pinpoint the source, try connecting real headphones β if the sound is going well, it is a false alarm of the sensor. If there is no sound with a real headset, the problem is deeper.
Method 1: Basic actions - reboot and check the connector
Start with the simplest steps. Often the error disappears after a banal reboot, especially if it is caused by a temporary system failure.
Turn off and turn on your phone (not a quick reboot!)
Try to connect and disable real headphones 2-3 times
Check the 3.5mm connector for debris (light with a flashlight)
Turn off Bluetooth in the settings (if it was enabled)
-->
If your model has a 3.5mm connector, check it for foreign objects, often getting stuck inside the fibers from clothes, dust, or even pieces of plastic from a case.
- π―οΈ Dental cleaning (carefully, without pressing on contacts!).
- π¨ A cylinder with compressed air (keep at a distance of 5-10 cm).
- π¦ Lantern + Magnifier β to make sure that the contacts are not bent.
β οΈ Warning: Do not use metal objects (needles, paper clips) - they can close contacts and damage the connector. Also avoid wet wipes: getting liquid into the connector will aggravate the problem.
If you have a problem after cleaning, try inserting and removing the headphones 10-15 times in a row. Sometimes this helps to βdevelopβ stuck contacts. On models without a connector (for example, Xiaomi 13 Pro), immediately move on to the next method.
Method 2: Reset Bluetooth and audio settings
If the problem occurred after using wireless headphones (AirDots, Sony WH-1000XM5, etc.), the failure could occur in the Bluetooth module.
- Open Settings β Connected devices β Bluetooth.
- Click on the three dots in the top right corner and select Clear Cache (if there is one).
- Remove all saved devices (click on the gear next to each and select Forget).
- Turn off Bluetooth, restart the phone and turn the module on again.
If this does not help, reset the audio system settings:
- Go to Settings. β Sound and vibration.
- Click More (or more depending on the version of MIUI).
- Select Reset Sound Settings (may be called Reset Default Settings).
π‘
After resetting Bluetooth, check if there are any hidden devices on the list. Sometimes the smartphone saves connections to headphones that have not been used for a long time, and they interfere with the correct audio work.
Method 3: Diagnostics through engineering menu (USSD codes)
Xiaomi smartphones have a hidden engineering menu where you can check the status of audio ports.
- Open the Phone app.
- Enter the combination: ##36446337## (some models may run #4636## β Audio).
- From the Hardware Testing menu, select Audio β Headset Mode.
- Look at the status: if it says Headset Inserted (even without the headset connected), then the connector sensor is working falsely.
Also in the engineering menu, you can run the speaker test:
- Select Audio β Normal Mode β Speaker.
- If the sound is going well, the problem is precisely in the connector or its driver.
- If there is no sound even through the speaker, the audio chip may break.
β οΈ Note: Do not change other settings in the engineering menu unless you are sure of their purpose. Incorrect settings can lead to loss of network or complete failure of the communication module.
Method 4: Cache cleaning and resetting MIUI settings
If the problem occurs after the MIUI update (e.g., before MIUI 14 or HyperOS), the audio driver's cache may be to blame.
- Go to Settings β Applications β Application Management.
- Press three points. β Showing System Processes.
- Find Media Storage (or Audio System) and select Clear Cache.
- Do the same for Bluetooth and Settings.
If cleaning the cache didnβt help, try resetting all settings (without deleting data):
- Settings β About the phone β Resetting settings.
- Choose Network Reset or Reset all settings (not to be confused with a full reset!).
- After the reboot, check if the headphone icon has disappeared.
| Action. | When it helps | Risks. |
|---|---|---|
| Cleaning up Media Storage's cache | After updating MIUI or installing applications | Minimum (replay history may be reset) |
| Resetting Bluetooth settings | If the problem occurred after connecting wireless headphones | You'll have to pair all the devices again. |
| Reset all MIUI settings | In case of system failures (for example, after firmware) | Reset Wi-Fi, brightness, sound profiles |
| Full reset (Hard Reset) | If nothing has helped (extreme measure) | All data except files on the memory card will be deleted |
Method 5: Checking through ADB (for advanced users)
If you're familiar with ADB (Android Debug Bridge), you can diagnose the problem more deeply. Connect your phone to your PC and follow the commands:
adb shell
su
dumpsys audioIn the output, look for lines from the headset or headphone. If it says state=connected, even though the headphones are not connected, then the failure at the level of the audio driver. To reset its state, do:
adb shell cmd media audio_set_parameters routing=0
adb shell cmd media audio_set_parameters force_use=0Then restart your phone. If the commands don't work, try turning off the forced use of your headphones:
adb shell settings put global force_use_headset 0What if the ADB does not recognize the device?
Method 6: Hardware breakdowns - when do you need repairs?
If none of the software methods worked, the problem is probably hardware, and here are the signs that the phone needs to be brought into service:
- π§ 3.5 mm connector physically damaged (bent contacts, traces of oxidation).
- π§ The phone fell into the water or was exposed to severe humidity (even if everything is dry on the outside).
- π The sound completely disappeared through the speaker and through the headphones.
- π The problem only appears when the phone is tilted (symptom of a departing plume).
- π₯ On the motherboard, darkening or swollen capacitors are visible (you need to disassemble the phone).
The cost of repair depends on the model:
- Replacement of the connector 3.5 mm - from 800 to 1,500 rubles (on Redmi cheaper, on Mi 13 more expensive).
- Cleaning / soldering contacts - 1000-2000 rubles.
- Replacement of the audio chip - from 3 000 rubles (requires a microscope and professional equipment).
- Repair after moisture is ingested - from 2,500 rubles (includes cleaning, replacement of plumes).
β οΈ Note: If the phone is warranty, do not open it yourself - this will void warranty obligations. Contact the authorized service center Xiaomi (list is available on the website mi.com).
