Why the headphone jack on the Xiaomi phone does not work: 12 reasons and how to fix

You plugged your headphones into Xiaomi, but the sound keeps going through the speakers and the device doesn't recognize the headset? Or the jack doesn't respond at all? The audio jack problem is one of the most common malfunctions in the brand's smartphones, and the causes can be both software failures and physical damage. In this article, we'll look at all the possible scenarios for why the headphone jack on Xiaomi stopped working, from banal contamination to hardware failures of the motherboard.

Feature of Xiaomi smartphones (especially Redmi Note models) 8/9/10, POCO X3 mi 10/11) — Using Type-C plugs that simultaneously transmit sound and charge the device, which complicates diagnosis because the fault can disguise itself as charging problems. We will help you clearly identify the source of the problem and tell you when you can do your own repair, and when it is time to carry your phone to the service center.

It is important: if your Xiaomi is a model without 3.5-mm connector (for example, Xiaomi) 12/13 or 4), The problem may be in the Type-C adapter. → 3.5 mm or in firmware settings MIUI. About this - in a separate section of the article.

1. Connector pollution: dust, moisture and contact oxidation

The most common cause of a broken socket is the accumulation of debris inside the socket, and dust, pile from pockets, skin particles, and even fine sand can block contacts, which makes the phone unable to recognize the connected headphones, especially for models with a 3.5 mm socket that is not protected from external influences (unlike the Type-C).

How to check:

• 🔦 Light a flashlight inside the connector - if you see debris, it must be carefully removed.
• 💧 If the phone came into contact with moisture (rain, sweat, condensate), the contacts could oxidize – this is manifested by a green or white coating.
• 🧲 When you plug in the headphones, the jack should be easy to snap. If the plug is hanging, the contacts are bent.

What to do:

1. Clean the connector with a toothpick with cotton wool dipped in alcohol (at least 90%).
2. To remove moisture, place the phone in a silica gel bag for 12 to 24 hours.
3. If the contacts are oxidized, try to clean them with a lasticide (soft, without abrasive).

⚠️ Warning: Never blow into the connector with your mouth - moisture from the breath will aggravate corrosion. Also avoid compressed air (canisters), as it can drive the garbage deeper.

💡

If the connector doesn't work after cleaning, try connecting the headphones to another device, and if they work, it's a problem with the phone, and if it doesn't, it's a problem with the headset.

2. Software failures: errors MIUI Application conflicts

Sometimes the headphone jack on Xiaomi stops working due to firmware failures or conflicts with installed applications.

• The phone doesn't switch to headphones, the sound goes through the speakers.
• The status bar displays the icon of headphones, but there is no sound.
• The connector works "once in", it recognizes the headset, then it does not.

Most often, the problem arises after:

• 📱 Updates MIUI (especially in beta versions).
• 🎵 Installations of third-party audio players or equals of sound (for example, ViPER4Android).
• 🔄 Resetting settings or restoring from backup.

How to fix it:

Check the sound settings in Settings → Sound and vibration → Audio effects

Turn off all sound equalizers (such as Dolby Atmos or Hi-Fi)

Restart your phone in Safe Mode (hold the power button) → "Restarting in Safe Mode")

Reset the sound settings to factory (Settings → System → Resetting → Resetting the sound settings)

Update MIUI to the latest stable version

-->

If the problem occurs after the update MIUI, Try to roll back to the previous version via Fastboot or Recovery. For instructions for a particular model, look at the forum 4PDA or XDA Developers.

⚠️ Note: On some Xiaomi models (for example, Redmi Note 10 Pro) after resetting the audio settings, the sound in the speakers may disappear.

Physical injuries: bent contacts and plume shafts

If the headphone jack on your Xiaomi stopped working after a fall, hit or careless connection of the headset, most likely, the contacts inside the socket or the plume connecting the connector to the motherboard are damaged.

Signs of physical breakdown:

• 🔌 The connector staggers or falls out of the body.
• 🔊 The sound appears only at a certain position of the plug (for example, if you press the headphones sideways).
• 💥 The phone is rebooted or turned off when the headset is connected.
• 🔋 Simultaneously with the connector problem, the charging stopped working (relevant for Type-C).

What to do:

1. Visually inspect the connector for bent contacts (use a magnifying glass).
2. If the contacts are bent, they can be gently straightened with a plastic toothpick (not metal!).
3. If the connector is wobbling, it's a sign of soldered mounting. You can't fix it yourself, you need soldering.
4. If the charging does not work with the connector, the problem is in the plume or power controller (diagnosis is required in the service).

On Xiaomi models with a 3.5 mm connector (for example, Redmi). 9A or POCO M3) The plume often departs due to frequent connections / disconnection of headphones. The average cost of replacing the plume in the service is 800-1500 rubles.

4.Type-C adapter problems → 3.5 mm (for models without connector)

If you don't have Xiaomi 3.5-mm connector (for example, Xiaomi) 12/13, Mix 4 Or Black Shark, you use an adapter to connect wired headphones, and that's often the problem:

• 🎧 The headphones are working, but the sound is interrupted or distorted.
• 🔋 Adapter warms up or phone doesn’t charge when connected.
• 🔊 The sound only goes through one earpiece.

Causes of adapter malfunction:

Note: Cheap adapters (especially no-name adapters) are often incompatible with the same adapters. MIUI lack of support USB Audio Class 2.0. We recommend using original adapters Xiaomi or proven brands like UGREEN or Baseus.

5. Conflict with Bluetooth and other wireless devices

Sometimes the headphone jack on Xiaomi doesn't work because of a conflict with Bluetooth devices, for example, if you've previously connected wireless headphones (AirDots, Sony) WH-1000XM4), And then you try to use wired phones, and the phone can hang on to the previous connection.

How it manifests itself:

• 🔗 Bluetooth icon in status bar burns, although headphones are disabled.
• 🎧 Sound goes through the speakers, but the settings show the connected device.
• 🔄 Rebooting the phone temporarily fixes the problem, but it comes back.

Decision:

1. Open the Settings. → Connected devices → Bluetooth and forget all the saved headsets.
2. Turn off Bluetooth completely and restart your phone.
3. If the problem persists, reset your network settings: Settings → System system → Resetting settings → Reset your Wi-Fi, mobile network and Bluetooth settings.

On some Xiaomi models (for example, Redmi Note 11 Pro)+) bug in MIUI 13, which causes the phone to "forget" to switch from Bluetooth to wired headphones. MIUI 14 or rollback MIUI 12.5.

6. Damage to the motherboard or audio codec

If all previous methods did not help, the problem may lie in a hardware malfunction:

• 🔧 The audio codec (the microchip responsible for sound processing) is damaged).
• 🔥 The controller burned out USB/Type-C (It is important when using non-original charging).
• 💻 Damaged motherboard (for example, after falling or getting moisture).

How to diagnose:

• 🔊 Check if the microphone is working (if not, the audio codec problem is a problem).
• 🔋 See if the phone is charging (if not, the power controller problem).
• 📱 Connect the headphones to another device through OTG-cable (if not working - the problem is the phone connector).

What to do:

In this case, self-repair is not possible - you need a diagnosis in the service center.

• Replacement of audio codec: 2000-4000 rubles.
• Repair/replacement of the Type-C controller: 1500–3,000 rubles.
• The interpling of the connector: 1000-2000 rubles.

⚠️ Warning: If the phone has been in water, don't turn it on and don't charge! Immediately take it to the service - corrosion on the board can worsen in a few hours.

7. Alternative ways to connect headphones

If the headphone jack on Xiaomi does not work, and repair is postponed, you can use alternative methods:

• 🎧 Bluetooth headphones (e.g. Xiaomi AirDots or Redmi Buds).
• 🔌 USB-C headphones (without adapter, connect directly to the connector).
• 📶 Wireless transmitter (for example, Bluetooth transmitter for old headphones).
• 💻 OTG-cable + external sound card (for audiophiles).

For models without a 3.5 mm connector (for example, Xiaomi 13) the best option — USB-C They provide better sound quality than adapters and don't require any additional adapters:

• Xiaomi Type-C Earphones (budget version)
• 1MORE Piston Fit (Balanced Sound).
• Sony MDR-EX450APC (premium quality).

If you use Bluetooth headphones, pay attention to the codecs:

• AAC — Balance of quality and stability (suitable for the MIUI).
• AptX is the best quality, but requires support with headphones.
• LDAC — High resolution, but can slow down on budget models.

To change the codec, go to Settings. → Connected devices → Bluetooth settings → Sound quality.
