Solving lip-sync issues on Sony Bravia TVs

What Causes Lip-Sync Issues?

There can be a number of different elements causing lip-sync delays, such as:

• A broadcaster issue or buffering problems on streaming and catch-up services.
• An outdated firmware edition of your TV’s operating system.
• An audio setting is incorrectly configured in your TV settings.
• A third-party audio device, like a soundbar or home cinema system.

Basic Steps to Try

Here are some initial steps and common fixes to try:

1. Turn the TV off and on again to refresh its internal processors in case they’re congested.
2. Ensure your TV is running its latest firmware edition:
   1. Turn on your Sony Bravia TV Select Settings, followed by System.
   2. Press About, then System Software Update.
   3. Select Software Update and follow on-screen guide.
3. Change video sources or channels to determine if the source/channel is the cause.

Further Things to Check

These steps are slightly more involved, but can help in rare circumstances when all else fails:

• Check if your TV is in Game Mode - set to off when watching TV, streaming or disc sources; turn-on when playing video games.
• Audio Delay Settings in your Soundbar/AV system (if connected) - certain soundbars and AV systems allow for time delay adjustments in their system settings.

• Select PCM (stereo) instead of Dolby Digital - Ideal to test if the lip-sync delay still occurs when using stereo sound instead of Dolby-encoded audio.
  • On TVs after 2019, select Quick Settings from your remote.
  • Press the Settings menu.
  • Press Display & Sound, then Audio Output.
  • Select Digital Audio Out, then choose PCM.
