Hi there, let's look at an example. Please attach the information requested in how to report a media playback issue. Thanks!

@LukeI came looking for anything related to this issue and this user [ @CharlesF] seems to be reporting the same issue. I have an Emby server on Windows, Version 4.8.11.0. I've isolated this issue to the Roku client (in my use case.) It seems it may have to do with how the Subtitle is formatted, but is not limited to embedded subs, as this behavior has occurred with .SRT files as well. In the example I'm providing, I was able to correctly see the subs on a Web client and on an AppleTV client, but nothing displayed on the Roku client. I found another version of this media, where I had noticed it working correctly on the Roku, and I checked both files with MediaInfo [included in the attachments] and I only noticed the S-TEXT/ASS does not seem to work on the Roku but does everywhere else and the other file where the S-TEXT/UTF8 formatted subs, work everywhere. I have included screenshots of the three clients and the behavior. I first tested the Web client and that starts around line 49710 in the log [embyserver-63879820516.txt]. The example uses is an episode of Bosch Legacy S03E03, and this is the S-TEXT/ASS embedded subtitle. Please advise if there is any more or other date/images needed. All the original testing is dated 2025-04-09. The secondary testing with a file that is working is from 2025-04-10. Thanks!
