Headphone icon on the screen Xiaomi Redmi: why speakers do not work and how to fix it

You plugged your headphones into the Xiaomi Redmi and then disconnected them β€” but the phone still thinks they're connected? There's a headphone icon on the notification panel, no sound in the speakers, and all attempts to reboot the device don't help? This problem is familiar to many owners of Redmi Note 10/11/12, Redmi 9/10 and other models of the brand, most often due to an audio jack malfunction, contact contamination or software conflict.

In 80 percent of cases, you can fix the problem yourself without visiting a service center, and in this article, we will look at all possible causes, from the common (contaminated connector) to the complex (damage to the audio codec), and give step-by-step instructions with illustrations and videos, and pay special attention to Redmi models with a Type-C connector, which often have problems due to the design features.

If you're in a hurry, use the quick fix at the end of the article, and for the rest of us, we've prepared a detailed analysis of the table of symptoms, tests, and hidden MIUI settings that even experienced users don't know about.

Why the phone thinks the headphones are connected (even when they aren't)

The headphone icon on the Xiaomi Redmi screen is not just a visual bug, it signals that the system physically or programmatically identifies the connected audio device, and the reasons can be divided into three groups:

  • πŸ”Œ Hardware problems: damaged connector, oxidized contacts, got moisture or debris.
  • πŸ“± Software failures: error in the work of the audio driver, application conflict, flight settings MIUI.
  • 🎧 External factors: Faulty headphones, adapters or cables that β€œcheat” the system.

The most common cause is contamination of the connector, and dust, pocket pile, or moisture can close the contacts, mimicking the connection of headphones, and second place is failure after the MIUI update, especially if you use custom firmware or beta.

Before you start repairing, you need to understand what exactly you are dealing with.

⚠️ Warning: Never use metal objects (needles, knives) - they can damage the connector contacts. If after cleaning the problem remains, the internal paths of the board may have oxidized.

Critical information: On Redmi Note 10 Pro and later, the Type-C connector often suffers from a β€œfalse connection effect” due to a design defect. If cleaning didn’t help, try turning off the OTG function in the developer settings.

Software solutions: resetting settings, software update

If the hardware is fine, but the headphone icon is still on, the problem is the software part.

  1. MIUI Update: Sometimes the bug is fixed in new firmware versions. Check for updates in Settings β†’ About Phone β†’ System Update.
