Sound goes out of sync while watching videos on Youtube, Mixer and Twitch. Especially on Twitch sound goes out of sync 99% of the time. On Youtube out of sync 50%. Mixer out of sync 45%. Sound also goes out of sync when playing video games. This happens like 20% of the time.
But on Twitch. just watch the stream for 30 - 45 minutes. Then the sound goes out of sync. This problem should be easily be recreated by the AMD testing team. It requires you to watch a stream on twitch and wait for the sound to go out of sync.
