If you've tried to flip sliders on the menu before, but the result didn't work, don't be too quick to blame the speakers. Most often, the problem lies in the wrong sound mode, the conflict of settings. HDMI Or even in the settings of a particular app (like YouTube or Netflix), we'll show you how to diagnose and fix each of these situations.

Basic sound setting: volume, mode and balance

Start by checking the obvious. Even if you think you've tried these settings before, reset them to the factory and reset them, and users often miss key points.

To open the sound menu:

1. Press the Settings button on the remote.
2. Go to Settings. → Sound (Sound in English version).
3. Select Volume and check the current level.

Factory equalizer presets rarely satisfy users. luckily, Xiaomi TV There's a manual setup that allows you to dot the sound with the frequencies:

Go to Settings. → Sound. → Equalizer: Here you'll see 5-7 sliders that correspond to different frequency bands:

• 🎵 60Hz and 120Hz are low frequencies (bass) and increase them for "saturated" sound in action movies or electronic music.
• 🗣️ 500 Hz to 1 kHz are the average frequencies that are responsible for voice. Raise them if you can't hear the dialogue.

Critical error: don't lift all sliders at once! This will cause distortion. You'd better pick 1-2 bands to amplify and slightly reduce the rest. For example, for movies, the best combination is the best combination: +3 dB per 120 Hz (bass) and +2 dB by 1 kHz (voice).

On models with Dolby Audio (for example, Mi). TV Q2 75′′ will be a separate Dolby Mode switch in the equalizer. Turn it on for surround sound, but note that in this mode, the manual equalizer setting will be blocked.

3. Connecting external acoustics: speakers, soundbar, headphones

Built-in speakers, even in top Xiaomi models, are losing out to external acoustics. If you want to get a theatrical sound, consider connecting:

• 🔊 Soundbar or sound panel (via HDMI ARC, optical output).
• 🎧 Headphones (by Bluetooth or through a 3.5 mm connector if it is in the model).
• 🎛️ AV-Receiver (for 5.1 or 7.1 multichannel sound).

For streaming services (Netflix, YouTube, Kinopoisk):

• 🎬 In the app settings (e.g. Netflix), check whether the volume limit for the "night mode" is worth it".
• 🔊 On YouTube, the sound may be quieter due to normalized volume. Turn it off in Google profile settings (on your computer).
• 📶 If the sound is interrupted, check the Internet speed: Dolby Digital requires at least 15 Mbps.

💡
