How to troubleshoot lip-sync issues (audio delays) with your BRAVIA TV

• If you're watching a TV program, try changing the channel to see if the issue occurs on other channels.
  • If it only occurs on one channel, the issue is with the broadcast rather than the TV.
    • We recommend contacting your broadcast network provider for further assistance. 
• Performing a factory reset of the TV may clear any settings or issues that could be causing the problem. 

If the issue occurs only with the soundbar, try the following possible solutions:

• Ensure the soundbar is connected directly to the TV.
  • This may point out issues in the way you have the devices set up or connected.
  • It’s possible the soundbar is connected to an external device first and then to the TV.
    • Poor setup: Soundbar → Receiver → TV.
    • Good setup: Soundbar → TV.
• Disconnect and then reconnect the soundbar's AC power cord.
• Change the surround setting of the soundbar to "Clear Audio+" or "Standard".
  • Note: This change does imply you won't be able to enjoy other soundbar effects.
• Reset the soundbar.
  • Refer to the product manual for exact steps.
• Check if a software update is available. 

• Ensure the TV connections are done correctly.
  • Good setup: Speakers → Receiver → TV.
• Disconnect and then reconnect the receiver's AC power cord.
• Reset the receiver.
  • Refer to the product manual for exact steps.
• Check if a software update is available. 

In this case, we recommend adjusting the Digital audio out, A/V sync, and/or Pass through mode settings.

Set 'Digital audio out' to 'PCM'

1. Open the Settings menu.
   • Using the Quick Settings button (for models released in 2019 or later):
     1. On the supplied remote control, press the Quick Settings  button.
     2. Select the Settings  icon.
   • Using the HOME menu button (for other models):

   • Select BRAVIA Settings → Digital audio out → PCM.
   • Select Sound → Digital audio out → PCM.

Change the current 'A/V sync' setting

Note: Not all Androids have an A/V sync setting.

1. Open the Settings menu.
   • Using the Quick Settings button (for models released in 2019 or later):
     1. On the supplied remote control, press the Quick Settings  button.
     2. Select the Settings  icon.
   • Using the HOME menu button (for other models):

Set 'Pass through mode' to 'Auto'

1. Open the Settings menu.
   • Using the Quick Settings button (for models released in 2019 or later):
     1. On the supplied remote control, press the Quick Settings  button.
     2. Select the Settings  icon.
   • Using the HOME menu button (for other models):

     2. Select the Settings  icon.

Notes:

• Not all Android TVs have a Pass through mode setting.
• If the Pass through mode setting is active, certain features (e.g. Google Assistant, TalkBack, Screen reader) will not output audio while playing content.
• If TalkBack is set to On, set it to Off: 
  1. Open the Settings menu.
  2. On the supplied remote control, press the Quick Settings button (for models released in 2019 or later), or the HOME menu button (for other models).
  3. Select the Settings  icon.
  4. Select Device Preference → Accessibility → TalkBack → Off.
• If the TV is connected to a home theatre system or soundbar via an HDMI or optical cable, the sound may be delayed due to the audio system's processing delays. In this case, the issue is not with the TV speakers.
• If a home theatre system is connected to the TV via an optical cable, change the A/V Sync or Audio Delay setting from either the TV or home theatre system (if available). 
  • Audio delay adjustments usually range from 0 to approximately 250 milliseconds.
• If the TV, soundbar, and receiver have an ARC HDMI input, there is no need to also connect the soundbar or receiver to the TV using an optical cable. The two devices should simply be connected via the HDMI ports marked with ARC.
