Updating this post to share my experience and resolution regarding this issue.
It was a bad HDMI cable that caused this to happen, so if someone tells you 'digital is digital' save yourself some (lots!) of frustration, tell them to go f*** themselves, and try a better/higher quality cable, or just another cable in general as yours may be somewhat defective (like mine was).
I wouldn't believe this myself, but can confirm it to be the case. No Exo update, app update, or Shield update fixed my issue, it was certainly the cable replacement.
Also replacing the cable fixed my other extremely annoying issue I was having! Every time I first started watching something, or unpaused something I was watching it took a couple seconds for the audio to make sound, the video would play but no sound for a couple seconds. New cable, and BAM! audio starts right at that moment with the video each and every time. I thought my receiver may have needed time to process DD, or the format, but nope. I had bought a new receiver and this issue persisted, super annoying since I didn't need a new receiver per say. However, I then replaced the HDMI cable and all was well.
I'd have tried this sooner, but it's routed through two walls (receiver stashed in basement), and ~20 feet in length, so not something I had sitting around.
To recap: This issue was the worst on my older generation Shield TV routed to a receiver, then routed back to my Tv.
The glitchyness was only present when using 'trick play' (not direct stream), and was pretty much resolved if I tuned to a channel, pressed pause for a couple seconds (build up a buffer), and then played. It didn't happen at all with local media playback, even media with DD or DTS audio (I don't have any Atmos material). It was only on Live Tv watching a program live (which made this super odd, and difficult to troubleshoot, lord knows I tried multiple things to resolve).
So........... Sorry for wasting everyone's time, but I really do appreciate the help in working to resolve this. Hopefully if someone has a similar issue (be extra suspicious if audio takes a while to start after unpausing a video, or just starting playback), try a different HDMI cable just to be certain.Go to the full post
