I found a lot of posts about it around the internet, and a lot of suggestions that don't work.. has anyone had the problem of their Fire streaming device losing audio sync and been able to fix it? It's bad on YouTube and Pluto, comes and goes on Prime, never happens to Netflix. Amazon is silent on the issue even though it goes back a few years. I've tried every combination of audio/video settings on the Fire itself, nada. Tried changing settings on the receiver, nada. Played around with WiFi settings on the router, nada. I'm about to go back to Roku.
