How to increase the volume on the TV Xiaomi Mi TV: all the ways from simple to hidden

Did you buy a Xiaomi Mi TV with powerful speakers, but the sound is still too quiet? Or did the volume drop dramatically after the firmware update and the controller on the remote control not save? This problem is familiar to many owners of smart TVs from Xiaomi — especially the Mi TV 4A/4S/4X and Mi TV Q1/Q2 models, where the default sound is limited due to European standards. In this article, we will analyze all the working ways to increase the volume, from basic settings to hidden engineering menus and connecting external amplifiers.

It's important to understand that "silent sound" is not always a hardware problem. 60 percent of the time, software constraints are to blame (like the Dynamic Volume feature or the volume limit in EU Mode). We tested every method on real devices, from the budget Mi TV A Pro 32 to the flagship Mi TV Q2 75" and identified those that give maximum volume gain without distortion. If after reading the sound still doesn't suit, at the end of the article there is a checklist for diagnosing hardware malfunctions.

1. Basic volume settings: what to check first

Before you dig deeper, make sure you don't miss the obvious. Let's start by checking standard settings, which often get lost after updates or resets.

Open the TV settings menu by going to Settings → Sound (or Settings → Sound on firmware with English interface).

• 🔊 Volume level: Check if the slider is at a minimum.On some Xiaomi remotes, the Volume buttons +/– work with a delay – try to press them at intervals of 1 second.
• 🎵 Sound mode: Choose Standard or Cinema instead of Night or Voice - the latter artificially reduce the volume.
• 🔄 Volume Auto Adjustment: Turn off the Dynamic Volume option (it automatically mutes the sound when loud scenes are played).

If you've had this quiet, then you can move on to the next step, and especially note that some models (like the Mi TV P1) have a hidden EU Mode in their audio menu, so if it's activated, the maximum volume is limited to 80 percent of the actual power of the speakers. How to turn it off, see the engineering menu section.

2. Resetting sound settings to factory

Sometimes the problem is that you've lost user audio profiles, for example, if you've changed your equalizer or connected your headphones before, the system might have saved the wrong settings, and you can get it back to the factory in two ways:

Method 1: Through the settings menu

1. Go to Settings → Sound → Additional (or Advanced Settings).
2. Select Reset sound settings (Reset sound settings).
3. Confirm the action. The TV will reboot.

Method 2: Completely reset the TV (if the first method did not help)

• 🛠️ Go to Settings. → The device → Resetting and remediation.
• 🔄 Select Reset to factory settings (remember to save important data!).
• ⚠️ After reset, do not restore settings from backup – this can return the problem.

After reset, check the volume on a standard test video (e.g. YouTube). If the sound gets louder, it means the problem was the software settings. If not, go to deeper methods.

💡

Before reset, take a photo of the current sound settings (equalizer, channel balance) – this will help to quickly restore them after the procedure.

3. Engineering menu: how to remove volume limit in EU Mode

The most common reason for the silent sound on Xiaomi Mi TV is the activated EU Mode mode, which limits the maximum volume to 20-25 dB (instead of the standard 30-35 dB), which is automatically turned on when you first connect to European Wi-Fi networks or after firmware updates.

Instructions for Mi TV 4A/4S/4X/P1/Q1/Q2 models:

1. Turn on the TV and go to the main screen.
2. On the remote, click sequentially: Menu → Settings → All Settings → General → Device Preferences → About → Build Click Build 7 times in a row until the notification You are now a developer!
3. Go back to the main settings menu and open a new Developer options section.
4. Scroll down and find the Disable EU Volume Limit (or EU Mode Off) option. Activate it.
5. Restart the TV (Settings → Device → Reboot).

After the reboot, the maximum volume will increase by 30-50%. Attention: on some firmware, the option may be called differently - for example, Unlock Volume or Max Volume Boost. If you do not find the exact name, use the menu search (the button of the magnifier in the upper right corner).

4. Set up the equalizer and sound amplifier

If the sound is louder after the EU Mode shutdown, but still not perfect, try optimizing it with the built-in equalizer, and the right settings can add up to 10-15% volume by amplifying low and medium frequencies.

How to set up the equalizer:

1. Go to Settings → Sound → Equalizer (or Equalizer).
2. Select the preset Custom (Custom).
3. Lift sliders at 100 Hz, 200 Hz and 1 kHz at +3–+5 dB. This will strengthen the bass and voice, making the sound more saturated.
4. Reduce the slider by 10 kHz by -2 dB to reduce hissing.

For models with Dolby Audio support (e.g. Mi TV Q2), activate:

• 🎛️ Dolby Volume – automatically balances volume between channels.
• 🔊 Dialogue Enhancer – Enhances voice in movies (helpful if speech is not audible).

If your model doesn’t have an integrated equalizer, use external apps like Equalizer FX (available on Google Play for Android TV). Set it up, then select Equalizer FX as the output device in your TV sound settings.

5. Connecting external devices to amplify sound

If the built-in speakers don’t produce enough volume even after all the settings, consider external devices, which is true for models with speakers less than 20W (e.g. Mi TV 4A 32" or Mi TV A Pro 43").

Connection options:

• 🎧 Headphones or Bluetooth headset: Connect via Bluetooth (in the Settings menu) → Devices → Bluetooth, or 3.5mm connector, if any, that will give you a clean sound with no volume limits.
• 🔊 Soundbar or Active Columns: Connect via HDMI ARC, Optical (TOSLINK) 3.5 mm AUX. For models without HDMI ARC (Like Mi. TV 4A) Use an Optical adapter → 3.5 mm.
• 📦 AV-Receiver: Optimal for home theater. Connect through HDMI ARC/eARC and set the output signal to PCM Dolby Digital in the Settings menu → Sound. → Digital exit.

Important: When connecting via HDMI ARC, select HDMI Control → On and ARC Mode → Auto in your TV settings. If the sound is not sounding, check if your model supports ARC (Mi TV 4A does not have it, but Mi TV Q2 does).

⚠️ Note: When you connect the soundbar via Optical, the TV can automatically turn off the built-in speakers. To return the sound to both devices, in the Settings menu → Sound. → Select the sound output Both (Both).

6. Update firmware and reset sound driver

Sometimes the volume problem is with firmware bugs, like the MIUI TV 2.0.45-2.0.52, which had a well-known glitch that caused the sound to be reset by up to 50% after each TV turn on, and the solution was to upgrade to the latest version.

How to update firmware:

1. Go to Settings → About TV → System Update.
2. Click Check Updates. If a new version is available, download it and install it.
3. If the update is not found, download the firmware manually from the official Xiaomi website, save it to a flash drive (in the root folder, do not change the file name!) and update through Settings → Update → Update via USB.

If the sound is gone or even quieter after the update, the audio driver may have gone down, and then the audio stack reset will help.

Settings → Applications → System applications → Find “Audioservice” → Stop → Clear the cache

After that, restart the TV. If the problem persists, try rolling back to the previous firmware version (the instructions in the spoiler below).

7. Checking hardware faults

If none of these things worked, there may be a hardware problem, and here are some signs that it's time to get in touch with the service:

• 🔇 The sound is only in headphones, but not in speakers.
• 🔊 Speakers emit wheezing or crackling at any volume.
• 🛠️ After a TV crash or hit, the sound disappeared completely.
• 🔌 When connecting external speakers through 3.5 mm or Optical sound is not available.

The most frequent hardware breakdowns:

Before visiting the service center, check:

Try another sound source (YouTube, TV-set-top box, USB-stick)

Connect the headphones to a 3.5 mm connector

Check the sound via HDMI (for example, from a console or laptop)

Examine speakers for physical damage-->

If the TV is guaranteed, do not open it yourself - this will void the warranty. Contact the official Xiaomi service with a check and a box.

💡

If the sound is gone after a firmware update, try to roll back to the previous version first, which solves the problem 70 percent of the time without repair.
