I suppose it’s not working as there is no sound coming from the center speaker (stereo only). I don’t have a Dolby light on my receiver to confirm this. When I use the HDHomerun app I get sound coming from all my speakers. But I do remember something I read about the Shield and a lack of AC3 decoder provided by Nvidia. So probably, it’s working because of passthough in HDhomerun app. If you’re not there yet in your roadmap it’s fine. I realize this is a new release. I just wanted to relay the information from the field. With android, the hardware is more diverse than in the apple world so each device might react differently. I’ve been watching TV in Channels since I got it this morning and so far no glitches. I’ve tried many things to date and Channels looks promising. Keep up the good work.
