4k Videos Freezing and Skipping on Fire TV Max



I’m pretty new to using Kodi so forgive me if I’m missing something easy here but I’ve been trying to use Plex for Kodi (dontpanickodi) on a Fire TV Stick 4k Max and I’m having issues with 4k content stuttering / freezing constantly (sometimes every few seconds, sometimes after a couple minutes), sometimes with the audio dropping out as well.

So far I’ve had this issue with MKV files playing TrueHD Audio and DTS-HD  and MP4 with DTS-HD (seemed worse on the MP4, basically unwatchable). Tried changing the audio track to AC3 5.1 and disabling passthrough and still had the same problem. On a 1080p movie with TrueHD I did not have the same issue. I’m running the firestick on wifi 6; don’t think it is a LAN speed issue since I don’t have the same problem when running Kodi on an XBOX One S. Hope I am not missing anything obvious; definitely far from an expert on any of this.

I read through this thread 377579 (thread) and while the issue seemed somewhat similar (mine is more frequent), I have Kodi updated to the latest nightly and it does not seem to help. I also updated SMB Client and caching settings to those recommended in the above thread. Log is linked below, playback starts around 08:08:09.781
