I commented on a different post yesterday as I was searching for “buffering” rather than stuttering but this sounds exactly like my issue.
I too for the last couple of months have been seeing frequent stuttering with direct play audio and video of 4K HVEC with Dolby Atmos EAC3 audio files on a 2019 shield tv pro. The server dashboard shows as “buffering” when this occurs. My setup is Shield TV → Denon AVR → Samsung TV.
Kodi can direct play the same files without issue as does other devices such as an Xbox Series X. There are network logs posted in that thread, mine look the same.
