Audio/Video Sync Adjustment Option
Regardless of what is causing your audio and video to be out of sync on your Amazon FireStick, you’re about to receive some great news—there’s a new solution to fix FireStick audio delay issues!
Recently, Amazon introduced a new mechanism to its Fire TV device systems that allow the user to manually adjust audio and video synchronicity. This means that no matter which one is lagging, you can speed up or slow down one component to match its counterpart.
If you have an Amazon FireStick model from 2020 or the Lite version, this is a compatible feature. Otherwise, you might have to wait a bit longer until the feature is introduced to your model.
How to use the new Audio Sync feature
So, now that you’re aware of this new option, you’ll definitely want to know exactly how to set it up, use it, and change it whenever you might need to. For example, if you change your connections periodically, you may have to adjust the speeds again to match.
Here’s the full process for accessing the Audio Sync feature on your FireStick:
- Navigate over to the Settings tab.
- Choose Display & Sounds, and then you’ll see a list of options.
- Select Audio from this list, and next choose AV Sync Tuning.
Great! Now you’ve found the feature. If it’s not there, check to make sure that your FireStick is updated to the latest version.
Once you reach the syncing screen, you’ll see directions on how to make sure your audio and video are synced. At this point, It will show you a bouncing ball on the screen along with a blue rectangle bar, as well as emit a beeping sound. If the ball hits the rectangle shape upon the beep, it’s in sync. Otherwise, you can adjust the slider accordingly until it does.
