Unable to play some video files on Chromecast with subtitles turned on

[movieguy94110 1]

Some files play just fine, others fail.  I'm using the iOS Emby app to connect to the Chromecast and initiate playback.  The files play just fine on the iOS app if I'm not connected to the Chromecast.

Ubuntu 22.04.2 LTS on an Intel NUC

Emby Version 4.8.0.39 beta (I was having the same problem on the stable version but saw that there might be a fix in the beta. No luck).

Any help appreciated!  Happy to attach more logs or try tweaking settings.

I've attached embyserver and the transcoding logs (I just obfuscated the path/filename) but I'm not sure which error is the smoking gun.  Maybe this one?

fwiw in this case the subs are PGSSUB, it's an mkv file, 1080p HEVC.  If I use an SRT sub file it plays fine on the Chromecast
