How to turn on the sound on the Xiaomi TV: from basic settings to reset the system

Xiaomi TVs are some of the most popular on the market due to the combination of price, picture quality and functionality. But even with such a technique, users face a typical problem: the sound suddenly disappears, becomes quieter or distorted. The reasons can be different from the accidental press of a button on the remote control to a firmware failure. In this article, we will discuss all possible ways to turn on the sound on Xiaomi Mi TVs, Redmi Smart TVs and other models, including hardware and software methods.

So it's important to understand that the algorithm of action is very specific, for example, if the sound is lost after the system update, it takes one approach, and if the problem occurs after the external devices are connected, it's a completely different approach, and we structured the material so that you can quickly find a solution for your case, start with the simplest ways, and gradually move on to more complex ones.

1. Checking basic settings: remote and volume

Before you dig into the TV settings, make sure that the problem is not related to basic things. Most often, users accidentally turn off the sound with a button on the remote control or turn the volume down to zero.

• 🔊 Press the Mute button (represented as a speaker icon with a crossed circle) on the remote.
• 📛 Check the volume slider: press the Volume buttons + Volume (usually located to the right of the Mute button).
• 🔋 Make sure that the remote has working batteries in it, and if the monitor on the remote does not burn when you press the buttons, replace the batteries.
• 🎯 Try using the remote from close range (1-2 meters) – sometimes the signal does not reach due to obstacles or a weak IR emitter.

If you don't have a sound after this manipulation, then you can move on to the next step, and it's also worth checking if you've activated night mode or Silent mode, which automatically lowers the volume at certain times of the day, and these settings are usually in the Sound → Additional settings section.

⚠️ Note: Some Xiaomi models (e.g. Mi) TV 4S or Redmi X50) The Mute button can be delayed. Press it twice at intervals of 1-2 seconds.

2. Checking connected devices and signal sources

If the sound is only lost when viewed via HDMI, USB or external speakers, the problem may lie in the signal source settings. Xiaomi TVs sometimes automatically switch audio output to the wrong device, especially after connecting new gadgets.

Here's how to check and fix it:

1. Press the Input (or Source) button on the remote and select the desired signal source (e.g. HDMI 1, TV, USB).
2. If you use external speakers or soundbars, make sure they are on and connected to your TV properly (via HDMI ARC, Optical or 3.5mm jack).
3. Go to Settings → Sound → Sound Output and select Embedded speakers (if you want to hear audio through TV) or the appropriate external source.

Pay special attention to the HDMI CEC settings (multi-device control function over one remote). Sometimes it conflicts with audio settings. To turn it off, go to Settings → Devices and Accessories → HDMI CEC and deactivate the option.

💡

If you connect the soundbar via HDMI ARC, make sure the cable supports this feature (there should be an ARC label on the connector).

3. Adjust the sound in the TV menu

If the basic methods didn't work, it's time to look at the system settings. Xiaomi TVs have flexible sound settings that sometimes get lost after updates or crashes. Here's a step-by-step recovery manual:

Go to Settings → Sound |

Make sure the volume slider is not at zero |

Select the correct sound output (embedded speakers or external device)|

Turn off Night Mode and Volume Alignment |

Check the sound format (should be PCM for most cases)

-->

Let's take a closer look at each item:

• 🔈 Volume: In the Sound menu, check that the main volume slider is not reset to a minimum. There may also be a separate balance regulator (left/right speaker) - make sure it is in the middle.
• 🎧 Output: If external devices are connected, the TV can automatically redirect sound to them. Choose Embedded speakers if you want to hear sound through TV.
• 🌙 Night mode: This feature lowers the volume of explosions and enhances dialogue, but sometimes it malfunctions.
• 🎚️ Equalizer: In the Additional Sound settings section, reset the equalizer settings to Default. Custom presets can suppress certain frequencies.

If you don't have the sound after this manipulation, try resetting the sound to the factory settings, and then in the Sound menu, find the Reset option (usually at the bottom of the list), which will return all the settings to the out-of-the-box values, but will not affect other settings on the TV.

⚠️ Note: Some Xiaomi models (e.g. Mi) TV Q1) The audio menu has a digital output option, and if it's activated, the sound may disappear when you connect through the audio. HDMI. Turn it off if you are not using an external receiver.

4. Firmware update and system reset

If the sound is gone after a TV update or the problem is systemic, it may be the firmware that is to blame. Xiaomi regularly releases updates to fix the bugs with the sound, but sometimes the updates themselves cause crashes. Here's what to do:

Method 1: Update via the Internet

1. Go to Settings → About TV → System Update.
2. Click Check Updates. If a new version is available, install it.
3. After the update, restart the TV (unplug for 30 seconds).

Method 2: Manual installation of firmware

If automatic updates do not help or the TV is not connected to the Internet, you can install the firmware manually:

1. Download the latest firmware version for your model from the official Xiaomi website (support section).
2. Copy the file (usually with the.zip extension) onto a flash drive formatted in FAT32.
3. Put the flash drive in. USB-TV port and go to Settings → On TV. → Update through USB.
4. Select the downloaded file and wait for the process to complete (don’t turn off the power!).

Method 3: Resetting to factory settings

If the sound problem is not solved, the last option is a complete reset of the TV, which will delete all user data, including installed applications and network settings, but often helps with system failures.

To reset the TV:

1. Go to Settings → About TV → Reset settings.
2. Select Reset all settings (may require input) PIN-code, by default 0000 or 1234).
3. Confirm the action and wait for the reboot (it will take 2-5 minutes).

💡

Resetting to factory settings is a last resort. Before you try to update the firmware and check the sound through external devices (earphones, speakers).

5. Hardware problems: speakers, connectors, boards

If the software methods didn't work, it could be a hardware malfunction, and here are the most common problems and their signs:

• 🔊 Faulty speakers: The sound is missing completely, but when you plug in your headphones or external speakers, it works.
• 🔌 Connector problems: The sound disappears when the cable moves into the HDMI Or 3.5 mm port, which indicates that the connector is damaged.
• 📱 Audio chip failure: The sound is distorted, wheezing or crackling often associated with overheating or power surges.
• 🔋 Faulty power supply: TV turns on but no sound and image flashes.Perhaps need replacement unit.

What you can do on your own:

1. Check the speakers for physical damage (cracks, dents). If they are external, press the membrane carefully - if you hear a crunch, the speaker is faulty.
2. Connect your headphones or speakers to a 3.5mm or HDMI ARC connector. If there's sound, the problem is with the TV speakers.
3. Try connecting the TV to another power source (for example, through another extension cord) and power surges can disable audio components.

If you don't have experience in electronics repair, you should contact a service center. Self-disassembly of a Xiaomi TV can lead to loss of warranty or exacerbate the problem. The average cost of repairing speakers is from 1,500 to 4000 rubles, depending on the model.

⚠️ Note: On Xiaomi TVs with Dolby Audio (e.g. Mi) TV Q1E) Sound problems may be due to incompatibility with some external devices. Try the audio menu to turn off Dolby Digital and select PCM.
