I used a Polk Soundbar, but it doesn't matter. They key is using "bluetooth". I also have some wireless bluetooth headphones and I connected these to the FireTV. As expected the audio sync issues were not present.
So, as long as you use bluetooth (soundbar, speakers, headphones) the sync issues should go away. Let me know if you try this out.
I am having the same problem with a fire stick so I purchased a new 4k fire stick and everything was good for about a week, then it started up again. I have fast fiber internet so it's not that. Is Dish going to figure this out or leave us hanging.
Hello Oscar. I know that this has to be frustrating to say the least. Have we tried walking through any troubleshooting steps, resetting the Fire Stick, and the TV itself?
