Just found this post. I’ve been experiencing this exact problem for a few months now (since early December 2021).
It actually prompted me to do a complete tear-down and rebuild of my Plex server implementation on TrueNAS to get the latest version. Still having the same issue after all of that.
I am not using TIDAL music, though the posts I keep finding point to issues with TIDAL.
or I find posts related to issues with Chromecast
But I’m specifically having issues with Podcasts playing in web browser version of Plex, not TIDAL music, and no issues with Chromecast.
Based off of some other random threads I found, I’m assuming this “h4” is some kind of audio codec that the browser version of Plex just cannot deal with.
I’m not really sure what to try next. Maybe another Plex server that isn’t running in TrueNAS? could the TrueNAS version of Plex be the issue?
