OPUS Audio Issues + Playback Correction Button MIA?

[EmbarkingSnow 0]

Hi!

I'm so sorry if I'm posting this in the wrong place as I haven't used a forum in a long time and while I did search I couldn't find anything that matches exactly.

The issue I'm having is that while I was able to watch anime I have with OPUS audio just the other day, it seems there's been an update and now it's not working.

I've so far found the best experience to be playing it via the XBOX app (I would prefer to use my LG TV + Emby app but I know they have OPUS issues and it wasn't worth the headache) but I've also tried tonight to play it via browser on my Mac (Firefox browser) and it just freezes and doesn't work.

When I've had this issue before I've used the Playback Correction Button in the settings but it seems to now be missing, so unless I want to change the quality from Auto to say 720 to force it to transcode (I have the Premium Version), it won't play at all and just sits there frozen. This is not ideal as I'm generally trying to watch things at 1080 etc.

Is there a way to force everything to just transcode automatically to avoid this issue? Even if the Playback Correction button is reinstalled it won't be ideal for Re:Zero for example as it plays little 2 minute skits between each episode so waiting for it to freeze on a failed direct play then forcing the transcode is really tedious.

Note I'm running a docker setup on a Synology NAS.

Thanks for any help and advice!
