Fixes: Amazon Prime Video Audio Out of Sync
Here is how to resolve Amazon Prime Video audio out of sync for the reasons described above, applicable to various devices, including PCs or Macs, Android or iOS mobile devices, Fire TVs, Apple and Samsung TVs, Sony and Roku TVs, and game consoles.
Internet Connection Check and Reconnect
If the issue is with the Internet, run a speed test on your device to check the connection. Just go to the Speedtest by Ookla homepage and click the Go button to check the speed of your Internet connection. Consider restarting the modem or router to assist reduce the problems with buffering if the connection is slow or choppy. If possible, switch to another network, such as a wired connection or a different Wi-Fi network, to check whether that makes the sync better.

Update the Amazon Prime Video App
Ensure that the Amazon Prime Video app is up to date on your device. Check the Google Play Store or App Store for updates if you’re streaming on a mobile device.
Reinstall the Amazon Prime Video App
Ensure you have the most recent firmware installed if you use a smart TV, set-top box, or streaming device. Updates are typically released for problem fixes and performance improvements. Plus, make sure your device is compatible with the most recent version of the app and any software upgrades. Consider uninstalling the Amazon Prime Video app, redownloading and reinstalling it, and then logging in with your account again if the issue persists.
Restart the Streaming Device
If possible, try streaming Amazon Prime Video from a different browser or device to see if the problem still exists. This can assist you in discovering whether the issue is specific to a browser or device. If the problem is with the device, restart the streaming device, computer, or smart TV. A simple restart can resolve a lot of issues, including video audio out of sync, black screens, and stuttering on Amazon Prime Video.
The process of restarting the device may vary based on its type. Usually, you can restart the Smart TV by heading to Settings, clicking Device Preferences, and selecting Restart. This will turn off and then turn on your television.
Try to stream Amazon Prime Video once more after restarting. Ensure you are not using the same account on several devices at once, since you can merely stream the same title on two devices simultaneously. And, make sure that any external device is connected to the display with an HDMI cable supporting HDCP 2.2 (for UHD and/or HDR content) or HDCP 1.4 (for HD content).
