I have been using the Fire TV Pendant 4k for a few years now and have noticed an annoying issue. The audio on certain programs seems to slowly not sync up with the video. The IPTV service I use gave me a fix but it's not permanent. I have to go into the audio settings and uncheck dolby digital and check stereo instead. Since I have a dolby digital audio system, it's not going to work for me. If I purchase one of the new 4K fire TV sticks, will that issue disappear?
