Hello! 
To fix issues with audio delay, go to Settings on your Fire TV and use the AV Sync Slider. For audio delay issues with a Home Theater setup, use Lip Sync Tuning instead. Here are steps to use the AV Sync Slider:
1. Go to Settings on your Fire TV. 
2. Select Display and Sounds. 
3. Select Audio. 
4. Select AV Sync Tuning. When audio and video are in sync, every bounce of the on-screen ball happens at the same time as a flash and a click tone. 
5. Make adjustments: Use the right and left buttons on your Fire TV remote. Move to the right if the click tone happens before the flash. Move to the left if the click tone happens after the flash. Press the Select button on your remote to apply the changes. Check if the ball, click tone, and flash sync up, and make adjustments as needed. 
I hope this helps solve any issues. Have a great day!
