Determine whether misaligned speech affects one programme, one app or the whole audio setup. Compare built-in speakers with the usual sound system if supported, then use the relevant documented sync control. Record whether sound is early or late and save original values. Adding delay at several stages can worsen the mismatch. A fault confined to one item should not automatically produce a global correction that makes all other viewing inaccurate.
Why it matters
Audio and video can follow different processing paths. A correction useful for one arrangement may not suit another. Locating the scope first prevents repeated adjustments across player, television and sound system, and gives support a concrete direction of mismatch rather than the ambiguous word delay.
Work through the steps
- Use a familiar speaking scene.
- Note whether audio leads or follows.
- Compare another item and supported output route.
- Adjust one documented control and recheck both.
What to avoid
Do not copy another setup’s delay value. Some controls affect only one side of the relationship. Avoid globally correcting a single poorly synchronised item and then forgetting that the adjustment affects the rest of the catalogue.
The useful takeaway
Find scope and direction before adjustment. One documented correction at the relevant stage is easier to maintain than several unexplained delays spread across the playback chain.
