on my new Yamaha A4A I have a Panasonic plasma tv, Sony Blue Ray player, Dish TV and the Roku 3810 streaming stick in the A4A HDMI inputs. Roku doesn't always start with sound, or if i pause the movie the sound is gone. to get the sound back I change the source to another HDMI input and then back to Prime and it works again. in all cases the video feed is fine. This is a new set up and this has happened on Prime Movies, but haven't checked to see if it occurs on Max or Netflix. I have run software updates for the A4A and Roku. All other sources are issue free. The Roku stick is about 3+ yrs old. Thoughts?
