Modern Xiaomi TVs are famous for their great picture and smart features, but built-in speakers often can not convey the full depth of modern movies or music. JBL acoustics owners are looking to fix this by connecting an external system through a digital interface. Using an HDMI cable is the most preferred option, since it allows you to transmit sound in high resolution without loss of quality.
The main advantage of this connection is that it supports ARC (Audio Return Channel) technology, or its improved version of eARC. This allows you to control the soundbar volume from the TV remote and automatically switch the audio output when you turn on devices. The correct setup of the Xiaomi TV and JBL Soundbar bundle turns regular TV watching into a full-fledged theatrical experience.
In this guide, we will take a closer look at all the steps of hardware connection, from choosing the right cable to fine-tuning the audio output settings in the Android TV system. You will learn how to avoid typical errors and why sometimes the sound may not appear immediately after you connect.
Required equipment and port preparation
Before starting the procedure, make sure you have all the required components.The basic element is the JBL soundbar itself, compatible with your tasks, and the Xiaomi or Redmi brand TV. It is critical to have a quality HDMI cable that meets modern data transmission standards.
Note the port marking on the back or side of the TV. To work with a return audio channel, you need a connector marked as HDMI (ARC) or HDMI (eARC). Conventional HDMI ports can stream video to the soundbar (if there is an input), but will not allow the TV to send sound back to acoustics without using an additional optical cable.
It is also worth checking the cable version. To transmit uncompressed multi-channel sound or formats like Dolby Atmos via eARC, it is recommended to use an HDMI 2.1 cable or a High Speed HDMI certified cable. Older cables may limit channel bandwidth.
⚠️ Note: Do not use adapters HDMI-DVI or HDMI-VGA to connect the soundbar, as they do not transmit an audio signal and can cause unstable operation of the system.
Make sure both devices are off before the physical connection. Although HDMI supports hot connectivity, in rare cases, this can cause the handshake protocol to crash, after which the TV will stop seeing external acoustics until it is fully restarted.
Physical connection and cable selection
The connection process begins with finding the appropriate connectors. On the JBL soundbar, find a port labeled HDMI OUT (ARC) or HDMI TV (ARC), which is a port designed to communicate with a TV, not to connect game consoles or consoles.
Insert one end of the HDMI cable into the HDMI OUT (ARC) port on the soundbar. then connect the other end of the cable to the HDMI (ARC) port on the Xiaomi TV. If your TV model has multiple ARC-enabled ports, it is usually recommended to use the one that is located closer to other media connectors or marked with a special icon.
After the physical connection, turn on the soundbar and then the TV. Android TV will automatically try to identify the new device. If a notification appears on the screen about the found JBL audio system, this is a good sign that the physical connection layer is working correctly.
- 🔌 Use a cable no longer than 3 meters long to minimize signal loss if possible.
- 🔌 Make sure the cable sits tightly in the connector; backlash can cause sound to disappear.
- 🔌 Avoid overbending the cable in the immediate vicinity of the plug.
Which HDMI cable to choose for JBL and Xiaomi?
Setting up the output of sound in the menu Xiaomi TV
Once the equipment is turned on, switch the output to the external system. Go to the main menu of the TV and go to the Settings section. You are interested in the Settings of the device or System, where the audio menu is located.
Select the Sound section and find the Dynamics or Audio Drive option. The default is "Dynamics TV" or "Automatic" and you have to manually select the option "External Speakers" or "Audio System" (HDMI/ARC), which will force all audio stream through the HDMI port.
Some versions of PatchWall or Google TV may call the settings differently.Look for Digital Exit and make sure the format is set to Auto or Pass-through.This will allow the TV to transmit the original bit stream without any additional processing, which is the responsibility of the JBL soundbar.

The main point or conclusion of this section
💡
The choice of "Pass-through" mode in the TV settings allows the JBL soundbar to decode complex audio formats on its own, ensuring the best sound quality.
If sound is available but only plays stereo, check the settings of the apps. Some streaming services require the inclusion of a high-quality audio option in their internal menus, regardless of the settings of the TV.
Activation of HDMI-CEC and ARC functions
HDMI-CEC (Consumer Electronics Control) technology is key for usability.It allows Xiaomi’s TV remote to control the volume of the JBL soundbar and turn it on simultaneously with the TV. On Xiaomi TVs, this feature is often called HDMI Control or HDMI-CEC.
To activate, go to Settings → Device Settings → Inputs. Find HDMI Control and switch it to On. Without this feature, you will have to use two remotes to control the system, which negates the ease of integration.
JBL soundbars can also have their own CEC settings. If the control from the TV remote is not working, check the acoustics instructions: sometimes you need to switch the login mode to the TV-ARC button on the body or the soundbar console. Some models require the inclusion of Anynet+ or similar in the menu of the acoustics themselves.
- 🎛️ Function CEC Allows you to turn off the soundbar with a single button.
- 🎛️ If you have problems with synchronization, try reconnecting the cable with the devices on.
- 🎛️ Make sure that the soundbar settings do not turn off the standby mode on HDMI.
⚠️ Attention: If, after activation, CEC The TV started to spontaneously turn off or change sources, try to turn off the function on one of the devices and restart the system.
Diagnostics of Sound and Image Problems
The most common problem is the lack of sound after you connect. First, check if the soundbar is the right source. Press the Source button on the JBL remote and select TV or HDMI ARC. The indicator on the body should light up with the appropriate color.
If the image on the TV is missing after connecting the soundbar (when using through-the-songbar video), check the cable. JBL Bar series soundbars often have HDMI input for signal sources. Make sure you don't confuse HDMI IN and HDMI OUT (ARC) ports.
If you have a slurring sound or cod, try changing your digital output settings. Go to Settings → Sound → Digital. Switch from Auto to PCM. This will lower the quality to stereo, but will help determine if the soundbar supports the stated formats or if there is a cable problem.
Resetting audio settings can help if a software failure interferes with the correct operation. In the audio menu, select Reset audio settings. This will return all equalizer and output parameters to factory values, often eliminating program conflicts.

Table of compatibility of ports and formats
Understanding the differences between ports helps avoid confusion, and here is a table describing the functionality of the various connections for Xiaomi TV and JBL bundles.
| Type of connection | Support for ARC | Maximum quality | Control of the TV remote |
|---|---|---|---|
| HDMI (ARC) | Yes. | 5.1 / Dolby Digital Plus | Yes. |
| HDMI (eARC) | Yes (Extended) | 7.1 / Dolby Atmos (Lossless) | Yes. |
| Optical (Toslink) | No. | 5.1 (compressed) | Partially. |
| Bluetooth | No. | Stereo (with compression) | No. |
As you can see from the table, HDMI eARC connectivity provides the best experience. If your Xiaomi TV and JBL soundbar support this standard, use it to get the most immersion in sound.
Optical output should only be considered as a backup if the HDMI port is faulty, it does not support modern object-oriented sound formats and requires separate soundbar volume control.
Optimization of sound quality and final settings
Once connected, fine tuning is a must. JBL soundbars often have their own equalizers and sound modes (Movie, Music, Voice) and switch them from the acoustics remote to find the optimal balance for your room.
In Xiaomi TV settings, turn off built-in audio enhancements like Volume Sound or Crystal Sound if they are activated automatically. Double signal processing (first with the TV, then with the soundbar) can lead to distortions and delays.
💡
Before updating, take a picture of the current settings of the TV on the phone – this will help you quickly restore them after resetting.
Check the synchronization of audio and video. If you notice that the sound is lagging behind the lip movements of the actors, look for the Audio Delay or Lip Sync settings in the soundbar settings. Adjust it until the desynchronization disappears.
⚠️ Warning: Long-term soundbar performance at maximum volume can cause the amplifier to overheat.
Regularly update the soundbar firmware via the JBL One app or via USB. Manufacturers often release updates to improve compatibility with Android TVs and fix HDMI-CEC protocol bugs.
