Common causes

  • A soundbar or receiver adding delay
  • Passthrough of surround audio the TV cannot handle

Work through these in order

  1. Change the player’s audio output from passthrough to PCM or stereo.
  2. Shift the sound with the player’s audio offset, 100 ms per try.
  3. Turn off any “sound effects” processing on the soundbar for a test.
  4. Switch to another channel: if only one is off, the issue is that source.

Still not right?

Tell us which channel drifts; sync problems at the source we can report upstream.

Usually one of these: a soundbar or receiver adding delay; passthrough of surround audio the tv cannot handle.

What if the steps do not help?
