Alan has a Roku Ultra, and after a month, it's starting to get out of sync, and it doesn't matter what app he's using. The video speeds up, but the audio stays the same. Alan has called Roku and they said to remove the apps and reinstall them. Unfortunately, it didn't fix the problem. Leo has a hunch it's a defective Roku device. Leo would demand they replace it. It may be a bandwidth issue, but Leo isn't convinced.
