Hello, I am building a Fire TV app with Fire App Builder. I am connected to my 4K Stick through ADB. My app has VOD and a live stream. Both are HLS. The VOD files play back fine the live stream has a lip sync issue. I searched the forum for the issue and found a post to adjust my audio settings to "Stereo" in case of incompatible TV. Did not solve the problem. I have also tried different streaming protocols DASH, & Smoothing Streaming. Still no change. I put the source stream url into VLC player and it is just fine. We also use the same HLS stream for our Roku Channel and no problems there. Just on Fire TV Stick I am seeing this problem. Can someone help me solve this problem?
