There’s nothing more immersive than watching a great movie—but when the sound lags behind the actors’ lip movements, the experience feels off. If you’re using a TV and soundbar combo, chances are you’ve experienced delayed or unclear audio at some point. These sync and clarity issues are especially common in homes that rely solely on HDMI ARC or wireless Bluetooth connections.

Take me, for example. When I upgraded my TV a while ago and paired it with a sleek new soundbar, I was expecting cinematic sound quality. Instead, I experienced delayed dialogue and occasional dropouts during action scenes. While the visuals were perfect, the delayed audio made everything I watched frustrating. That’s when I started thinking: is optical audio better than HDMI? Would switching cables really solve my problem?

TV Soundbar Setup FAQ

Here are the common issues I, and many other users, encounter:

• Audio delay or lip-sync mismatch: This issue is usually caused by a delay in signal processing between the TV and soundbar via HDMI ARC or eARC.

• Distorted or muffled audio: Compression in wireless or HDMI connections can degrade sound quality.

• Device compatibility errors: Not all TVs and soundbars support the same HDMI audio formats, leading to inconsistent performance.

While HDMI delivers both video and audio, it’s not always reliable for top-notch audio quality and sync accuracy. That’s where Optical Digital Audio Cables come in handy.

How Optical Digital Audio Cables Solve the Problem

Optical cables use light signals instead of electrical currents to transmit audio, which reduces interference and signal loss. I replaced my HDMI ARC connection with an optical cable and saw an immediate improvement:

• No more sync issues: The soundbar syncs perfectly with the on-screen action.

• Clearer sound: Dialogue is crisper, and background music no longer drowns out vocals.

• Better compatibility: My older devices worked perfectly with the optical input, while HDMI struggled.

Back to the main question: is an optical audio cable better than HDMI? In many cases—especially when audio clarity and synchronization are more important than Dolby Atmos or high-bandwidth formats—the answer is yes.
