Connecting a soundbar to a Xiaomi TV via Bluetooth: The Complete Guide 2026

Connecting a soundbar to a Xiaomi TV via Bluetooth is one of the most convenient ways to improve sound without unnecessary wires. However, many users face problems: devices “can’t see” each other, sound is interrupted, there are delays. In this article, we will discuss all the nuances of wireless connection of the soundbar to Mi TV, Redmi Smart TV and other Xiaomi models, including hidden settings and solving typical errors.

It’s important to understand that the process can vary depending on the MIUI TV firmware version and soundbar model. We’ll look at the universal steps that work on most devices, and also pay attention to specific cases – for example, when the TV does not support A2DP (protocol for high-quality audio) or the soundbar requires a special connection sequence.

If you've tried to connect devices before, but you've failed, don't give up. 80 percent of the time, it's done by setting up codecs, resetting a Bluetooth module, or updating software. Next, you'll find a step-by-step instruction with illustrations (interface descriptions), a compatibility table, and answers to frequent questions.

1.Preparation: check of compatibility and requirements

Before you start connecting, make sure your Xiaomi TV and soundbar meet the minimum requirements:

• 📺 Television: Any model with MIUI TV version 3.0 and above (Mi TV 4/4A/4S/5, Redmi Smart TV X/L, etc.) Older versions (e.g. Mi TV 3) may not have Bluetooth.
• 🔊 Soundbar: must support the A2DP (for music streaming) and AVRCP (for playback control) profiles. Most modern models (e.g. Xiaomi Mi Soundbar, Sony HT-S40R, JBL Bar 5.1) are compatible.
• 📶 Distance: The device must be no more than 10 meters (no obstruction) and walls, furniture and other Bluetooth devices (e.g. wireless headphones) can interfere.

To check the version of MIUI TV, go to Settings → About TV → MIUI version. If your firmware is outdated, update it through Settings → Software Update. This can solve connection problems.

Focus on Bluetooth codecs. Xiaomi TVs usually support SBC (basic codec) and AAC (for better quality). Some soundbars (such as Soundcore Infini Pro) work with aptX or LDAC, but MIUI TV doesn't support them. If the sound is "hacking" or interrupted, the problem may be the codec.

2. Step-by-step instructions: how to connect the soundbar to Xiaomi TV via Bluetooth

Follow this instruction to connect devices. If a step doesn't work, don't skip it, but check for alternative methods (they're listed below).

1. Put the soundbar in pairing mode. Usually, you need to press and hold the Bluetooth or Pair button on the remote or the device body, and the indicator should start flashing blue or white.
2. Activate Bluetooth on your TV. Go to Settings → Devices → Bluetooth (some models may have different paths: Settings → Network & Connections → Bluetooth).
3. Start searching for devices. Turn on the Bluetooth slider and wait for your soundbar name to appear on the list (e.g. Mi Soundbar or SB-XX123).
4. Connect to the soundbar. Select it from the list and confirm the pairing. If you need a PIN- code, try the standard options: 0000, 1234 or look in the soundbar instructions.

After successful connection, the sound from the TV should be automatically transmitted to the soundbar. If this does not happen, check the audio output settings:

1. Go to Settings → Sound → Sound output.
2. Choose Bluetooth audio or the name of your soundbar.
3. Make sure the volume control on the TV and soundbar is set to a comfortable level.

If the sound is late (especially in movies), try turning off the sound processing in the soundbar settings or switch the TV to Game mode (Settings → Picture → Image Mode).

3. Typical problems and their solutions

Even with the right connection, there can be problems, and here are the most common ways to fix them:

💡

If the soundbar has previously been connected to another device (such as a smartphone), reset it to factory settings, usually by pressing and holding the Power and Bluetooth buttons simultaneously for 10 seconds.

If none of these methods worked, try resetting your Bluetooth settings on your TV:

1. Go to Settings → Devices → Bluetooth.
2. Select Device Management (or Device List).
3. Find your soundbar, click on it and select Forget the device.
4. Restart the TV and reconnect.

4.Alternative ways to connect the soundbar to Xiaomi TV

If Bluetooth isn't stable, consider other connectivity options. Everyone has their pros and cons:

• 🔌 HDMI ARC/eARC: better sound quality (including Dolby Atmos), but requires compatible cable and port on the TV. Suitable for Mi TV Q2, Redmi MAX 98 and other models with HDMI 2.1.
• 🎧 Optical cable (TOSLINK): It transmits multi-channel audio without delay, but does not support some formats (e.g. DTS:X).
• 🔴 Analog AUX (3.5 mm): versatile, but the sound quality is worse than that of digital interfaces. Suitable for older soundbar models.
• 📶 Wi-Fi (for smart soundbars): Some devices (such as the Xiaomi Mi Soundbar Pro) support local area network connectivity.

To choose the best way, answer the questions:

• Do you need surround sound (for example, for movies)? → HDMI ARC or optics
• Is it important to have no wires? → Bluetooth or Wi-Fi
• Does the soundbar have a microphone input (for karaoke)? → AUX or Bluetooth with HFP support.

If you choose to use an optical cable, pay attention to the type of cable. To transmit sound in Dolby Digital Plus format, you need a cable with a bandwidth of at least 12 Mbps. Cheap cables can cut high frequencies.

5. Sound adjustment after connection

After successful pairing, it is recommended to optimize the sound settings, which is especially important if you use the soundbar to watch movies, games or listen to music.

The following settings are available on Xiaomi TV:

• 🎚️ Equator: in Settings → Sound → Equalizer you can adjust the frequency response (amplify bass or tops).
• 🔊 Sound modes: Standard, Movie, Music, News. Movies, Movie, it activates virtual surround.
• 🎤 Microphone (if supported): Some soundbars (e.g. Xiaomi Mi Soundbar) allow karaoke microphones to be connected, activated in Bluetooth device settings.

On the soundbar itself, there can also be useful options:

• 🔄 Night Mode: smooths out loud sounds (good for watching at night).
• 🎵 3D Sound: It creates surround sound even without the rear speakers.
• 📱 Mobile App: Many soundbars (e.g. from JBL or Sony) have their own apps for fine-tuning.

💡

For better sound, turn off the TV's built-in speakers. You can do this in Settings → Sound → TV speakers → Off.

If you use a PlayStation (Xbox) soundbar, connect the console directly to the soundbar via HDMI or optical cable, which will reduce the latency that is critical in games.

6. Update firmware and reset settings

If connectivity or sound problems persist, it may be the legacy firmware that is to blame.

For Xiaomi TV:

1. Go to Settings → About TV → Software Update.
2. Click Check for updates.
3. If a new version is available, download it and install it. Don't turn off the TV while you upgrade!

For the soundbar:

• Use the official manufacturer’s app (e.g. Mi Home for Xiaomi soundbars).
• Connect the soundbar to the Wi-Fi network and check for updates in the Firmwer section.

If the update doesn’t work, reset your Bluetooth settings on your TV:

1. Go to Settings → Devices → Bluetooth.
2. Select Additional (or ⋮ in the upper right corner).
3. Press Reset Bluetooth Settings.
4. Confirm the action and restart the TV.

💡

After resetting Bluetooth, all the associated devices (earphones, gamepads, etc.) will be removed. Write down their names in advance so that you can quickly reconnect them.

If the soundbar still doesn't work, try resetting it to factory settings. This is usually done with a long press of the Reset button (see device instruction).

7.Comparison of Bluetooth with other ways of connecting

To understand whether you should use Bluetooth or choose a different interface, compare the key parameters:

Bluetooth is easy to watch and music, but not good for moviegoers because of the delay. If you care about quality, choose HDMI ARC or optical cable. AUX may be good for retro games or karaoke.
