Audio sync off only on DVR content.

We have been noticing lately that anything we have recorded (DVR) is having issues with audio not syncing with video properly. We have been using the same setup for several years and have not changed anything other than the normal app/server updates. We also have Plezy installed, switch to that, and same thing.

TV is a Samsung QN65Q80R connected to a 3rd gen Firecube. Everything is wired, right next to each other, including the server. Oh, and the Plex server is running on Truenas Scale.

Suggestions on how to resolve?
