    Depending on the sound source output from devices (Blu-ray Disc Player, set-top box (STB), game consoles), the sound may lag behind the picture, or the picture may lag behind the sound. If this is the case, select the solution which corresponds to the connected source device.

    When the source device is connected to the Home Theater System/Soundbar via HDMI

    If the Home Theater System or Soundbar has a SYNC (A/V sync) function, adjust the setting and see if the issue improves. For how to change the A/V sync setting, refer to the Home Theater System or Soundbar's manual.

    • 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 Theater System or Soundbar supports the Sony | BRAVIA Connect or Sony | Home Entertainment Connect app, you can adjust the delay using the following steps: SettingsSound SettingsAV Sync.
      • If your TV is a BRAVIA, change the A/V sync setting from Auto to Off or On. For details, refer to the TV's Operating Instructions or Help Guide.

    • If the above workaround does not work well and your Home Theater System or Soundbar has an HDMI terminal, connect the source device directly to the Home Theater System or Soundbar using an HDMI cable. For details on the connection method, refer to the Home Theater System or Soundbar's Startup Guide or Help Guide.
      Note: If you want to connect many devices to the Home Theater System/Soundbar and the number of HDMI terminals is insufficient, connect the source device that delays the sound to the Home Theater System/Soundbar via HDMI first. If no more HDMI terminals are available on the Home Theater System or Soundbar, connect other devices to the HDMI terminals on the TV.
