    • Auto (Dolby Digital): Choose this option if your audio system supports Dolby Digital decoding and you have a compatible setup.
    • Stereo: Select this option if you are using external speakers that do not support surround sound or if you want a basic stereo output.
  • Ensure that your external speakers or audio system are correctly connected to your TV or Roku device. Make sure that all cables are securely plugged in.

  • Press the ‘Options’ (*) button on your remote.
  • Select ‘Check for updates.’

HDMI cables are essential for connecting your Roku to your TV and ensuring audio and video synchronization. If you’re experiencing audio sync issues on Roku, the HDMI cable may be a potential source of the problem.

Check the connections of the HDMI cables are tightened properly. If you find any loose connection, tighten it. Make sure the HDMI cable is fully inserted.

If you find any damage to the HDMI cable, you need to replace it.

Ensure that you’re using an HDMI cable that supports the necessary features for your setup. For example, if you’re trying to transmit 4K content, make sure you’re using an HDMI cable that supports 4K (HDMI 2.0 or higher).

Connect a different HDMI port (e.g., a Blu-ray player or game console) to the same HDMI input on your TV and external audio device. This will help determine if the issue is specific to the Roku TV or if it’s a general HDMI connection problem.

People watch Netflix, Amazon Prime, and other streaming platforms on Roku. These streaming platforms require a good internet speed. If the internet speed is slow or unstable, it will create issues with the audio and video synchronization. You will hear an audio delay on the Roku.

Sometimes, a simple router system restart can resolve temporary connection issues. Unplug your router from the power source, wait for about 30 seconds, and then plug it back in. Give it a few minutes to reconnect to the internet and then check if the audio sync issue persists.

If the Wi-Fi- keeps disconnecting from the Roku TV, try to connect the Roku TV directly to your router using an Ethernet cable. The speed of the internet is high in the wired connection and more stable.

Disconnect all other devices that are connected to the Wi-Fi. Multiple devices consume a significant amount of speed and you get low speed for the Roku device.

Regularly restart your router to clear the cache and refresh your network connection. Unplug the router, wait for about 30 seconds, and then plug it back in.
