The audio and video are out of sync when using an HDMI connection with a home theatre system or soundbar

• If your TV has a function that delays the image (A/V sync setting), try adjusting that setting. For details, refer to the TV's manual.
  Hints:
  • If your home theatre system or soundbar supports the Sony | BRAVIA Connect or Sony | Home Entertainment Connect app, adjust the delay by going to Settings → Sound Settings → AV Sync.

• If your TV is a BRAVIA, try the following settings on the TV:

  • Change A/V sync from Auto to Off or On.
  • Change eARC mode to Auto.
  • Change Pass through mode to Auto, or change Digital audio output to Prioritize pass through.

  Hint: The menu item varies depending on the model. You can find the above settings by going to Settings → Display & Sound → Audio Output, or Settings → Display & Sound → Audio Output → Audio System Settings. For details, refer to the BRAVIA's manual.

  Examples of the settings:
  • Quick Settings → Settings → Display & Sound → Audio output → Pass through mode
  • Quick Settings → Settings → Display & Sound → Audio output → Audio system settings → Digital audio output → Prioritize pass through 

 For BRAVIA Theatre Quad (HT-A9M2) / BRAVIA Theatre Bar 9 (HT-A9000) / BRAVIA Theatre Bar 8 (HT-A8000)

For BRAVIA Theatre Bar 6 (HT-B600, HT-BD60) / BRAVIA Theatre System 6 (HT-S60) / HT-S2000

For HT-A9 / HT-A7000 / HT-A5000 / HT-A3000

If the above workaround does not work well and your home theatre system or soundbar has an HDMI terminal, connect the source device directly to the home theatre system or soundbar using an HDMI cable. For details on the connection method, refer to the home theatre system or soundbar's Startup Guide or Help Guide.

Note: If you want to connect many devices to the home theatre system or soundbar and the number of HDMI terminals is insufficient, connect the source device that delays the sound to the home theatre system or soundbar via HDMI first. If no more HDMI terminals are available on the home theatre system or soundbar, connect other devices to the HDMI terminals on the TV.
