But an HDMI-connected setup can have a sound-and-picture timing mismatch when a TV, source device, soundbar, or AV receiver processes audio and video at different speeds. Replacing the cable is not a general fix; first work out whether sound or picture is late, then check the settings and signal route involved.
What “HDMI audio lag” usually means
People often say HDMI is causing lag when they notice that sound and picture do not arrive together. That describes a problem somewhere in the connected system, not proof that the HDMI cable itself is responsible. HDMI notes that lip-sync mismatch can become more challenging as devices perform more processing and audio and video travel through multiple paths, such as a TV plus a soundbar or AV receiver. HDMI’s Latency Indication Protocol overview discusses synchronization in complex installations.

The mismatch can go either way: sound may follow the picture, or the picture may follow the sound. The useful first question is which one is late. The answer affects which sync control to try and which part of the signal path to investigate.

How an HDMI setup can develop a timing mismatch
A TV may process the picture while audio travels to a separate soundbar or receiver, or the source device may handle the two signals differently. When several devices and routes are involved, their processing can create a mismatch. The symptom alone does not identify a faulty component; compare the affected source and route before changing settings.

ARC and eARC are ways for a TV to send audio back over HDMI to an AV receiver or soundbar. eARC also supports advanced audio formats. Their presence describes connectivity and audio capabilities; it does not by itself show that ARC or eARC is causing delay. HDMI explains the return-audio connection in its HDMI Specification 1.4b overview and TV audio explainer.
Diagnose the mismatch before changing settings
- Identify the direction: Is sound behind the picture, or does the picture appear behind the sound?
- Compare sources: Check whether the issue affects TV apps or broadcasts, or only one external device, such as a game console, disc player, or set-top box.
- Trace the route: Note whether the source connects to the TV first and sends audio onward to the sound system, or connects to the soundbar or receiver first.
- Locate available controls: Check the TV, soundbar, receiver, and source manual for sync or audio-output settings. Names and menu paths vary by model.
This comparison helps narrow down which device path to adjust. Sony’s HDMI source-to-home-theater troubleshooting guidance and TV-to-sound-system sync guidance likewise distinguish between sources and connection paths.

Try model-specific sync and audio settings
Use the sync control that matches the route
Look for settings named A/V Sync, AV Sync, Lip Sync, or Audio Delay. Depending on the setup, the useful control may be on the soundbar or receiver, or on the TV. Do not assume that turning a sync feature on—or increasing its value—is always correct: the adjustment must compensate for the signal that is late. Follow the exact product’s instructions.
Check TV audio output options where available
For some TV and sound-system combinations, Sony recommends checking options such as eARC mode set to Auto, pass-through set to Auto, or digital audio output set to prioritize pass-through. PCM is another possible troubleshooting test in some setups, but it can change the output format from the original. These are model-dependent tests, not universal fixes. Confirm the available settings and format trade-offs in the TV manual and manufacturer support page.

Test a different signal route
If the soundbar or home theater has an HDMI input, try connecting the affected source directly to that device rather than routing it through the TV. Sony recommends this route in applicable cases. It can help some setups, but results depend on the equipment and source.
For gaming, consider low-latency display mode
Auto Low Latency Mode (ALLM) lets a compatible source signal a display to enter a low-latency mode. That is intended for gaming and other interactive use, where display response matters; it is not a general lip-sync correction. Some picture-processing features may be reduced or stopped in that mode. HDMI describes ALLM separately from synchronization protocols.

What HDMI lip-sync features can—and cannot—do
LipSync capability
HDMI says LipSync functionality was introduced with HDMI 1.3. Supported devices can track and correct processor delays to help keep audio and video synchronized. That capability does not mean every device or connection supports the same behavior. See HDMI’s feature archive and specification overview.

HDMI 2.2 introduces the Latency Indication Protocol (LIP), which HDMI describes as helping source devices determine latency adjustments and mitigate audio/video timing differences in complex, multi-device systems. It is a specification feature, not evidence that existing equipment supports it: compatible implementations are required. HDMI’s LIP feature page describes the protocol.

ALLM is for interactive latency, not lip-sync measurement
ALLM and LIP address different needs. ALLM signals a display to use a low-latency mode; LIP concerns adjustments for audio/video timing differences. Enabling a gaming-oriented mode should not be treated as a fix for every mismatch.
When to consult the manufacturer
If the mismatch persists after checking the relevant sync control, output options, and a possible alternative route, consult the manuals and support pages for the exact TV, source, and audio-system models. Available controls, supported formats, and menu names differ between products. Sony’s support articles provide examples of model-specific troubleshooting, not settings that apply to every HDMI setup.
