Hello!
So I have been a shield TV user for about a year, and have been experiencing this same issue since day one. With the 2017 model of the Shield TV (non-pro) the audio will cut out every 10-20min or so. After attempting to find a solution I only found that other people were experiencing this as well and there did not seem to be any concrete fix. So, after the release of the 2019 models I figured I'd give it a shot and purchased the 2019 Shield TV (also non-pro). Started to watch Iron Man 1 streamed over plex and got about 1 hour and 40 minutes into the film without any hitches, causing me to comment to my roommate something along the lines of "ah its so nice not having any audio issues." As if cued by my words the shield then dropped the audio about a minute after. Since this I have been experiencing the same exact issues as I had on the 2017 model except that they occur about once an hour vs once every 10 minutes. The drops are for maybe 3-5 seconds max. I am using the shield in companion with a Sonos setup. I have tried nearly everything that people have seemed to suggest; disabling HDMI passthrough, disabling CEC, etc and have not yet fixed the issue. This is not a problem strictly for plex as well, the issue has presented itself during Gamestream as well. I've only had the new device for a few days but this is extremely annoying as I had hoped this would be the fix. Any ideas or suggestions would be greatly appreciated
I've been noticing the same issue on the 2019 "tube" and would love to hear what others have to say as well!
