Connection method guide
Below are the main ways to connect your TV to your sound system: HDMI ARC/eARC, optical cable, Bluetooth, and analog connections. Correct port alignment is important to ensure good sound quality.
HDMI ARC/eARC connection
HDMI ARC (Audio Return Channel) and eARC (Enhanced Audio Return Channel) allow you to send audio from your TV to your sound system using the same HDMI cable. First, find the HDMI ARC port on your TV, which is usually labeled "HDMI ARC" or "HDMI 1 (ARC)." On your sound system, look for the port labeled "HDMI OUT (TV ARC)."
Connect a high-quality HDMI cable between both devices. If you are using eARC, it is recommended to choose an HDMI 2.1 standard cable for the best results. After connecting, turn on the TV, go to the audio settings and activate the ARC function (it may be called “HDMI ARC”, “Audio Return Channel” or “eARC”). On the sound system, select HDMI ARC as the audio source. If everything is connected correctly, the sound will come through the external system and the TV speakers will be turned off.
Optical cable connection ( TOSLINK )
An optical cable transmits sound using pulses of light, which reduces signal loss [2] . First, remove the protective caps from the ends of the cable. On your TV, find the port labeled "Optical Out" or "Digital Audio Out," and on your sound system, find the port labeled "Optical In" or "Digital In."
Connect the ends of the cable to the appropriate ports, just make sure they are inserted correctly. If your sound system has multiple digital inputs, remember which one you are using (e.g. AV1, AV4). In your TV settings, select "Optical Out" or "Digital Audio Out" as the output option, and in some cases you may need to disable the internal speakers. Finally, select the correct input on your sound system.
Wireless Bluetooth connection
Bluetooth connectivity allows you to stream audio without cables, which is extremely convenient. Turn on the “Bluetooth” or “Wireless Devices” function in the TV settings. At the same time, activate pairing mode on the audio system - this is usually done by long-pressing the “Bluetooth” button or via the menu.
Once your TV has detected your sound system, select it from the list and wait for the devices to connect. Although Bluetooth is fast, it is important to keep the devices within about 10 meters of each other to ensure a stable connection [1] . If you are having trouble, check for obstructions such as walls or other electronic devices.
Analog connections (AUX, RCA)
Analog connections such as AUX and RCA are suitable for older devices, providing simple stereo audio transmission.
- AUX connection: Connect a 3.5mm cable between the TV's headphone or Audio Out port and the AUX In or Line In port on your audio system.
- RCA connections: Use a red and white RCA cable. Connect to the Audio Out ports (red for right, white for left) on your TV and to the corresponding Audio In ports on your sound system.
After connecting, select external audio output in the TV settings and turn off the internal speakers. Select the correct input on the sound system and adjust the volume to achieve the desired result.
Comparison of connection methods
Each method of connecting your sound system has its strengths and weaknesses. The right choice depends on the equipment you have, the features of your TV, and your personal needs.
Advantages and disadvantages
Let's review the main aspects of each method.
HDMI ARC/eARC provides high-quality, lossless audio transmission. It supports up to 8 channels of compressed audio, such as Dolby Digital or DTS , and up to 32 channels of uncompressed PCM audio [3] . eARC extends the capabilities even further, allowing for advanced formats such as Dolby Atmos or DTS:X . However, not all TVs and sound systems, especially older models, support this technology.
Optical cable is an excellent choice when immunity to electromagnetic interference is required. The signal is transmitted in pulses of light, so the sound is clear and distortion-free. [3] [4] [5] However, this method only supports up to 2-channel PCM audio and compressed formats such as Dolby Digital or DTS [3] [4] , and newer formats such as Dolby Atmos or DTS:X are not supported. [3] [4] [5] [7]
Bluetooth offers the ultimate in convenience – no cable clutter and quick connection. However, the compression does come at a cost in terms of audio quality. The SBC codec limits stereo audio to 512 kbit/s, and even the LDAC codec, which reaches 990 kbit/s, is unable to deliver Dolby Atmos [6] . Bluetooth can also have audio latency issues.
Analog connections (AUX, RCA) are simple and compatible with older devices. However, they are susceptible to electrical noise, so the sound can be less accurate than digital connections [8] .
Comparison table
| Connection method | Sound quality | Supported formats | Setup complexity | Price | Delay |
|---|---|---|---|---|---|
| HDMI eARC | Highest | Dolby Atmos, DTS:X, TrueHD, up to 32 channels | Average | Medium | Minimal |
| HDMI ARC | High | Dolby Digital, DTS, up to 8 channels | Average | Medium | Small |
| Optical cable | Good | Stereo PCM, Dolby Digital, DTS | Simple | Low | Small |
| Bluetooth | Medium | Stereo (compressed) | Very simple | None | Medium-high |
| Analog (RCA/AUX) | Low-medium | Stereo only | Simple | Very low | Minimal |
HDMI eARC is the best solution if your equipment supports it. It not only reduces latency, but also allows you to enjoy the latest audio technologies [7] . Optical cable is a reliable option for basic surround sound, but it does not support the latest formats. Bluetooth is great for everyday use, where convenience is more important than sound quality, and analog connections are a solution for older equipment.
When choosing a connection method, it's important to consider the capabilities of your sound system and the content you're watching. If you often enjoy movies with Dolby Atmos sound, HDMI eARC will be the best choice. Below, we'll discuss the most common connection problems and their solutions.
Common connection problems and their solutions
Even if you follow the instructions, you may not be able to connect your audio system the first time. Many users encounter similar situations, but they can often be solved with fairly simple methods. Here are some of the most common problems and their solutions.
No sound after connection
One of the most common cases is that the equipment is connected, but there is still no sound. First, check the sound settings on your TV. Make sure that the sound is not muted on either the TV or the external sound system. Also, check that the TV settings are configured to use the external sound system.
If you are using an HDMI ARC connection, make sure the cable is connected to the correctly labeled HDMI port. Check your TV settings and make sure the external audio system you have selected is in accordance with the manufacturer's instructions. If you are using an optical cable, make sure it is connected to the correct port.
The TV cannot find the sound system
Bluetooth connections can sometimes cause problems due to incorrect setup. Both devices must be turned on and in pairing mode. Press and hold the Bluetooth button for a few seconds until the indicator starts flashing.
If the TV still cannot find the sound system, delete old Bluetooth entries and start the process again. Make sure the devices are close to each other (no more than 10 meters) and there are no thick obstacles between them. Check that both devices have the latest software, as this often helps to resolve compatibility issues.
Audio lag and sync issues
When using a Bluetooth connection, you may experience audio lag, causing the audio to not match the video. If this happens, check if your TV or sound system has a sync adjustment feature. Most devices allow you to manually adjust the sync - start with small adjustments until the audio and video are in sync.
If you are using an HDMI ARC connection, enable the CEC feature on both devices. This will not only allow you to control both devices with a single remote, but may also improve synchronization. If you are using an optical cable, check the audio format settings on your TV. If the format is not compatible with your sound system, select another format, such as PCM or Dolby Digital, to ensure proper audio playback.
These simple steps often help resolve connection issues and ensure the system works as expected.

FAQ
What is the difference between HDMI ARC and eARC connections, and how do you choose the right one for your sound system?
HDMI ARC and eARC: What's the difference?
HDMI ARC ( Audio Return Channel ) allows you to pass audio from your TV to your sound system, supporting standard audio formats such as Dolby Digital and DTS . This is a great solution if you use a conventional sound system and want to enjoy quality sound in comfort.
Meanwhile, eARC ( Enhanced Audio Return Channel ) is a more advanced version of this technology. It provides higher data throughput and allows the transmission of high-resolution audio, including Dolby Atmos and DTS:X formats. This means that with eARC you can enjoy uncompressed, highly detailed sound, which is especially suitable for modern audio systems.
What do you need to know about the choice?
The main difference between HDMI ARC and eARC is eARC's ability to transmit uncompressed audio. If you have a modern sound system and are looking for the best possible sound quality, eARC is a better choice. However, there are a few important things to check before using eARC:
- Device compatibility : Both the TV and the sound system must support the eARC function.
