During playback of Amazon videos, the background music plays normally, but there is no voice soundtrack. Lips move, background music plays, but no voices. I tried playing several different videos, Justified, Fringe, but it's the same for everything from Amazon. The sound is fine on TV pass through, in the YouTube app, playing DVDs, but not through the Amazon app. I can play Amazon videos like normal using Roku. My setup FYI:
1. DVR -> hdmi -> X1 -> hdmi -> TV
2. DVR= MotorolaDCT-6416
Did a power cycle today to fix the 0x8027025a error code issue, but that didn't fix the Amazon app sound issue.
