When I open the app everything is fine. As I'm streaming and it goes to commercial, the sound randomly stops at the beginning or the end of the commercial and continues muted when the episode or movie continues. This only happens on this new Roku and doesn't happen on other Roku devices in my home. This also only happens in the Netflix app and does not happen on any other streaming apps. Besides changing the audio out to stereo from auto and rebooting, I reset the Roku to factory settings this morning. It still happens but, it's important to say that it's random. No one show or movie has it happening consistently. The beginning or end of the commercial triggers it when it happens, and audio stays out. Hitting the back button and going back into the stream restores audio until the next time it happens. Also, this never happened with the Roku I had in this setup prior. I'll try and take a video but, it's not easy to predict when it's going to happen.
