This problem is familiar to many owners of a smart TV from a Chinese brand. Most often, ghost sounds appear after updating the firmware, resetting or accidentally pressing buttons on the remote, 80% of the time are to blame for built-in services like live radio, background music or voice prompts that are activated without the user’s knowledge.

You'll learn how to turn off the audio program through the settings menu, reset the audio settings to factory settings, and what to do if the sound is "hang" and does not respond to commands. Separately, we will consider rare cases when the problem lies in a hardware failure - and how to check it without contacting the service center.

Why Xiaomi TV is the sound itself: 4 main reasons

Before you start to "treat," it's important to understand what's triggering the audio program, which is not a malfunction in most cases, but a feature of the firmware. Here are the most common scenarios:

📻 Automatic radio or music service on some models (e.g. Mi) TV 5 Pro) in the background is running FM-radio or streaming service like Xiaomi Music, which can be activated after an upgrade or when connected to Wi-Fi.
🎤 Voice assistant. If you accidentally press the Google Assistant button on the remote or say, "OK, Google," the system can turn on voice prompts that sound over the main content.
🔄 Resetting audio settings: After updating the firmware or resetting to factory settings, the TV can return sound settings to default values, including demo audio videos.
🛠️ Hardware failure: In rare cases, the problem is the chip of the sound processor or the firmware damage, which manifests itself as a "hang" sound that is not turned off in any way.

If the sound only appears when the TV is turned on and disappears after 5-10 seconds, it is most likely a screensaver system (for example, the PatchWall greeting), in which case you do not need to turn off anything, it is normal behavior.
