Sure I saw this mentioned, can’t find it now.
Input Firestick (HD version)
Output audio via 3.5 Jack
Playback of some videos in Amazon prime result in device totally locking up with audio stutter and no response from remote, resulting in 10-30 seconds of locked video and audio loop then final crash and reboot.
Can be replicated with same movie.
Playback from this firestick to TV error free
