HDMI Audio Delay: Why Lip Sync Feels Off (And How to Fix It for Gaming)
Audio delay is not always obvious until you notice it — then everything feels ‘late’. In gaming, audio delay can ruin timing cues. The common causes are TV processing, soundbar modes, and complex ARC/eARC routing.
Fix Order (Practical)
- Enable Game Mode on the TV input (reduces processing latency).
- Avoid extra audio processing modes while testing (virtual surround, enhancements).
- Simplify the path: console → TV → output, or console → receiver (not both).
- Use eARC only if it’s stable; otherwise test direct connection.
Signs It’s the TV/Audio Path
- Delay changes when switching TV picture modes.
- Soundbar modes change timing noticeably.
- Lip sync issues appear mostly on one input/path.
Rule: gaming prefers the shortest stable path. Complex HDMI routing is for convenience, not latency.
