Battle of Quality: HDMI versus Optical Audio - Which Option Suits Your Soundbar Best?
In the realm of audio connections, two popular options stand out: HDMI ARC (Audio Return Channel) and Optical. Both have their strengths and weaknesses, making them suitable for different scenarios.
Advantages of HDMI ARC
HDMI ARC offers several advantages over Optical, making it a preferred choice for modern devices.
- Advanced Audio Formats: HDMI ARC supports formats like Dolby Atmos, Dolby Digital Plus, and True HD, providing better sound quality and enhanced surround sound capabilities.
- Simplified Connections: HDMI ARC carries both audio and video signals through a single cable, reducing clutter and simplifying connections.
- Improved User Convenience: HDMI ARC also supports features like HDMI CEC, allowing automatic control of volume and playback across devices, enhancing user convenience and integration.
- Better Compatibility: HDMI ARC is generally more compatible with modern TVs and soundbars, especially those designed for home theater setups.
Advantages of Optical
Optical connections, while older, still have their place, particularly in specific situations.
- Interference-Free Signal: Optical connections are immune to electromagnetic interference (EMI), ensuring a clean and stable audio signal especially in electrically noisy environments.
- Longer Cable Runs: Optical connections are suitable for larger rooms or complex setups due to their ability to transmit audio signals over longer distances.
- Compatibility with Older Equipment: Optical connections are compatible with older audio and video equipment that lacks HDMI ARC ports.
- No Ground Loop Issues: Optical connections do not suffer from the ground loop hum or buzz that can sometimes occur with electrical HDMI connections.
Disadvantages
Both HDMI ARC and Optical have their drawbacks.
HDMI ARC Disadvantages
- Slightly shorter recommended cable length
- Susceptible to EMI compared to optical
- May have occasional compatibility issues with some older devices
Optical Disadvantages
- Supports fewer audio formats and no advanced surround sound like Dolby Atmos
- Audio only, requires separate cables for video
- Manual configuration may be needed, no automatic device control
Making the Right Choice
When both your TV and soundbar support HDMI ARC, it is the better choice for quality, convenience, and future-proofing. Optical is often a better option for older equipment, longer cable runs, or interference-proof connections. While Optical still delivers solid surround sound quality, it lacks some advanced audio features HDMI ARC supports.

In the realm of audio connections, the modern lifestyle prefers HDMI ARC for its support of advanced audio formats like Dolby Atmos, simplified connections, improved user convenience with HDMI CEC, and better compatibility with home theater setups. On the other hand, Optical connections remain relevant in specific situations, offering an interference-free signal, longer cable runs, compatibility with older equipment, and resistance to ground loop issues. However, both connections have their drawbacks; HDMI ARC has slightly shorter recommended cable length, is susceptible to EMI compared to optical, and may have occasional compatibility issues with some older devices. In contrast, Optical supports fewer audio formats and no advanced surround sound like Dolby Atmos, requires separate cables for video, and lacks automatic device control features. When making the right choice for audio connections, HDMI ARC is favorable for quality, convenience, and forward-thinking considerations, while Optical proves more effective in dealing with older equipment, longer cable runs, or electrically noisy environments [1, 2, 3, 4, 5]. Meanwhile, in the domains of fashion-and-beauty, food-and-drink, home-and-garden, technology, travel, cars, and shopping, individuals can curate their unique lifestyles as they journey through the captivating world of hobbies and consumerism.
