Audio "Delay" (Latency) in Videos
4.5
The sound doesn't match the lips of the people talking in the video.
Symptoms
- Lip-sync issues
- Delayed sound
- Lag
Possible Causes
- Bluetooth latency
- Old Bluetooth version (SBC codec)
- App processing lag
Step-by-Step Fix
1
Use a Low-Latency Codec
Ensure your device is using aptX Low Latency or AAC.
2
Restart the Video App
Apps like YouTube often have built-in delay compensation that can fail.
3
Use Wired Connection
The only way to achieve zero latency for gaming or editing.
When to See a Technician
Bluetooth always has some delay; modern codecs and apps work together to hide it, but it's never perfect.
