How to bring sound back to Xiaomi: from simple settings to complex solutions

You have played a video on Xiaomi Redmi Note 12 or run music on Mi TV Q2, Or is the speaker starting to wheez and the headphones are jamming? Sound problems on Xiaomi devices are more common than you think — and the reasons can be very different, from accidentally turned off the "Do not disturb" mode to a physical breakdown of the speaker. In this article, we will analyze all possible scenarios why the sound disappears, and give step-by-step instructions for its recovery - from basic checks to deep technical settings.

It's important to understand that the algorithm of actions depends on the type of device (smartphone, TV, headphones) and the nature of the problem. For example, if the sound is lost only in a particular application (say, YouTube or TikTok), the solution will be one. If the speaker does not work at all, it will be completely different. We structured the material so that you can quickly find your case and not waste time on unnecessary manipulations.

Before you go to drastic measures (like resetting or disassembling the device), make sure that the problem is not the trivial things. According to service centers, 60% of the time, Xiaomi’s sound is lost due to software failures that the user can fix on their own in 5-10 minutes.

1. Checking basic sound settings

The first thing you need to do is eliminate the human factor, and often the sound is turned off by accidentally pressing buttons or changing the settings, and this is what we check first.

• 🔊 Multimedia Volume: Press the physical volume button on the side panel of your smartphone. A slider will appear on the screen - make sure it's not at zero. On Xiaomi TVs, volume is regulated by buttons on the remote or via the Settings menu → Sound.
• 🔔 Do Not Disturb Mode: Swipe down from the top of the screen (on your smartphone) and check if the crossover bell icon is activated. On TV, this mode may be called Quiet Hour (Settings) → System system → Quiet hour).
• 🎧 Connected devices: If you have Bluetooth headphones or speakers connected to your smartphone, the sound can automatically switch to them. Open the notification panel and turn off unnecessary devices.
• 🔕 Silent mode: on some models (for example, POCO X5) There's a separate silent switch on the sidebar. Make sure it's not activated.

• 🔄 Sound mode: Some firmwares have separate profiles (e.g., "Night Mode" or "Cinema") that can turn down the volume. → Sound. → Sound mode → Standard.

⚠️ Note: If you use Xiaomi with custom firmware (like LineageOS or Pixel Experience), some audio settings may be in other menu sections. → System system → Additionally. → Sound.

2. Diagnostics of hardware problems

If the basic settings are fine but still no sound, it's time to check the hardware.

1. Damage to the speaker (rupture of the membrane, ingress of moisture, mechanical damage).
2. Connector problems (oxidation of contacts in 3.5 mm audio jack or USB-C).
3. A malfunction of the sound chip (occurs less frequently, usually after falls or overheating).

Preliminary diagnosis can be carried out independently:

To check the speaker on the smartphone:

1. Connect the headphones – if there is sound in them, the problem is in the phone’s dynamics.
2. Call your phone from another device – if the sound of the call is there and the media is not, the problem is in the settings or firmware.
3. Record a voice message and listen to it – if the recording is played, but there is no sound from the speaker, the plume may be damaged.

⚠️ Note: If your Xiaomi fell into the water or was subjected to a strong vibration (for example, in a backpack while cycling), do not try to disassemble it yourself. moisture could get on the board, and when turned on, this can cause a short circuit.

💡

On Xiaomi smartphones with an infrared port (such as the Redmi Note 10 Pro), you can check the speaker using the remote control from the TV. Point the IR port at the speaker and press any button — if you hear a high-frequency squeak, the speaker is working.

3. Program failures and their elimination

If no hardware problems are detected, the sound may have been lost due to firmware failure, application conflict, or incorrect settings.
