How to connect the soundbar to the Xiaomi TV: all ways with step-by-step instructions

Modern Xiaomi TVs (Mi TV 4S/5/5X/Q1/Q2/A Pro series) are equipped with powerful speakers, but for real movie-philes or music lovers, their capabilities are often not enough. Soundbar solves this problem by providing surround sound with bass and clear high frequencies. However, connecting external acoustics to Xiaomi Smart TV has nuances - from choosing the right cable to adjusting the sound output in the TV menu.

In this article, we will analyze all the current ways to connect the soundbar (including HDMI ARC, Bluetooth, optical output and AUX), compare them on sound quality and complexity of setting, and give recommendations for eliminating typical problems — from lack of sound to audio delay. If you are just planning to buy a soundbar, at the end of the article there is an FAQ with tips for choosing a model for specific tasks.

1.Preparation: What to Know Before Connecting

Before you combine the soundbar with the Xiaomi TV, check out three key points:

• 🔌 There are connectors on TV and soundbar. For example, the Mi TV Q2 75" has HDMI ARC, optical output and Bluetooth 5.0, and budget models like Mi TV 4A can only cost AUX 3.5 mm.
• 🔊 The audio format that supports your TV. In the Settings menu → Sound → Digital audio output should be selected PCM (for base sound) or Dolby Digital (for surround sound).
• ⚡ Power: Some soundbars (e.g., Xiaomi Mi Soundbar) require a separate power supply, others are powered by a USB- TV port.

A critical novice error: connecting the soundbar via HDMI to a normal port (not ARC) will result in no sound. The HDMI ARC port is usually signed on the back of the TV or highlighted in a different color. If it is not, use optics or Bluetooth.

2. Method 1: Connect via HDMI ARC (best quality)

HDMI ARC (Audio Return Channel) provides the highest sound quality (including Dolby Atmos and DTS:X) and allows you to control the soundbar volume from the TV remote. This method is recommended for Xiaomi Mi TV Q1/Q2, Redmi Smart TV X and other flagships.

Step-by-step:

1. Connect one end of the HDMI cable to the HDMI ARC port on your TV, the other to the HDMI ARC (or HDMI OUT) port on the soundbar.
2. Turn on the soundbar and put it into HDMI mode (usually with the Source or Input button).
3. On the TV, go to Settings → Sound → Sound Output and select HDMI ARC.
4. Activate the HDMI Management (CEC) option in the Settings menu → System → Connection devices to sync remotes.

If the sound doesn't come up,

• 🔄 Reboot the TV and soundbar (unplug for 30 seconds).
• 🔧 Check that the soundbar settings have ARC enabled (some models do this by holding the Source button).
• 📺 Update the TV firmware: Settings → On TV. → Updating the system.

⚠️ Warning: On Xiaomi’s 2019–2020 TVs (e.g., Mi TV 4S 55) you may need to manually activate HDMI ARC via the service menu.

1. Open the Settings. → On TV.
2. 5 times click on the Mi logo at the top of the screen.
3. Enter the password 12345 (or 00000 for new models).
4. Go to Service → HDMI Settings and turn on ARC Support.

3 Method 2: Optical Connection (TOSLINK)

Optical cable (TOSLINK) transmits digital audio without loss, but does not support formats higher than Dolby Digital 5.1. This method is suitable if the TV does not have an HDMI ARC (for example, Mi TV 4A or Redmi TV 70).

How to connect:

1. Connect the Optical Out port on TV to the Optical In port on the soundbar using the TOSLINK cable.
2. On the TV, select Settings → Sound → Digital Audio Output → Optical.
3. Set the PCM sound format (for stereo) or Dolby Digital (for 5.1).
4. On the soundbar, activate Optical mode (Source button).

Typical problems and solutions:

💡

If the optical port on the TV is closed with a plug, don't remove it, it protects the connector from dust. Just insert the cable with force, the plug will move automatically.

4. Method 3: Connecting over Bluetooth

Wireless Bluetooth connectivity is convenient for temporary use (for example, listening to music from a phone) or if the soundbar does not support wired interfaces. However, the latency (latency) can reach 100-200 ms, which is critical for movies.

Instructions for Xiaomi TV:

1. Turn on the soundbar pairing mode (usually by holding the Bluetooth or Pair button until the indicator blinks).
2. On the TV, open Settings → Connection devices → Bluetooth.
3. Select the soundbar from the list of available devices.
4. Confirm the conjugation (if necessary, enter the PIN-code, usually 0000 or 1234).

How to reduce the latency of sound:

• 🎵 Use the aptX Low Latency codec (if supported by soundbar and TV).
• 📶 Reduce the distance between devices (optimally up to 3 meters).
• 🔋 Disable other Bluetooth devices (earphones, keyboards) that may cause interference.

⚠️ Warning: Xiaomi TVs based on Android TV 9 and older can automatically turn off Bluetooth audio when switching to HDMI- input. To avoid this, select Bluetooth as a priority source from the Settings → Sound → Output menu.

Method 4: Connecting via AUX (3.5 mm)

The analog output of 3.5 mm (AUX) is even on Xiaomi’s budget models, but the sound quality will be worse than that of digital interfaces, a method suitable for older soundbars or portable speakers.

Step-by-step:

1. Connect the AUX Out port on your TV to the AUX In port on the soundbar using a 3.5mm jack cable.
2. On the TV, select Settings → Sound → Sound Output → Analog (AUX).
3. Adjust the volume on the soundbar (on some Xiaomi models, the volume through AUX is fixed at 70%).

Frequent errors:

• 🔌 Use cable with damaged contacts (check for cod when the wire is moving).
• 🔊 Connect to the AUX In port on a TV (it is designed for external sources, such as tape recorders).
• 🎛 Volume discrepancy: If the TV is at its maximum and the soundbar is at its minimum, the sound will be distorted.

💡

Analog connection (AUX) doesn't transmit multichannel audio, just stereo. For surround sound movies, use HDMI ARC or optics.

6. Method 5: Connect via USB (only for some models)

Some soundbars (e.g., Xiaomi Mi Soundbar or Redmi Soundbar) can be connected to the TV via the USB- port, but this only works for power, not for audio transmission. Except for TV models with support for USB Audio (e.g., Mi TV Q1 75" 2022).

How to check compatibility:

1. Connect the soundbar to the USB- TV port.
2. Open Settings → Connection Devices → USB- Devices.
3. If you have the option to use as an audio device, select it.

If you do not have an option, the USB- port can only be used to charge the soundbar (the sound will have to be transmitted via Bluetooth or AUX).

7. Sound adjustment after connection

After the physical connection of the soundbar, you need to optimize the sound parameters on the Xiaomi TV:

• 🎚 Sound balance: From the Settings menu → Sound → Equalizer, select Preset Movie (for movie) or Music (for listening to tracks).
• 🔊 Volume: Turn off Volume Auto and Night Mode to avoid surges of sound.
• 🎤 Microphone: If the soundbar has a built-in microphone (e.g., Xiaomi Mi Soundbar Pro), activate it in the voice control settings.

To check the sound quality, use the YouTube test videos (search for "Dolby Atmos test" or "5.1 surround sound test"). If the sound comes only from front speakers, check the output settings on the TV - Dolby Digital or DTS should be selected.

💡

To avoid echoes when connecting over Bluetooth, turn off the 3D- effect on the TV from the Settings → Sound → Effects menu.

8 Problem Solving: No sound or delay

If the soundbar does not work after connecting, use this instruction:

To diagnose latency (sound delay) when connecting via Bluetooth:

1. Open on TV Settings → System → About TV → Software version.
2. If the Android TV version is below 10, update the firmware – Bluetooth sync is improved in the new versions.
3. In the soundbar menu, activate Game Mode or Low Latency (if any).

⚠️ Warning: Xiaomi TVs with an Amlogic T962 processor (e.g., Mi TV 4S 55" 2020 year) may experience audio delay through HDMI ARC when viewing content at a resolution 4K @60Hz Solution - lower the resolution to 4K @30Hz or 1080p in the settings HDMI.
