Server Version#: 1.41.3.9314  
Player Version#: Web 4.143.0; Windows: 1.106.0.276-fe8d1d20

I’m trying to figure out why my Plex Subtitle auto-sync isn’t working. I have had all the options enabled for weeks, but it seems that my scheduled tasks are not ever detecting voice activity. Is there something I need to do to get voice activity? It’s causing some WAF issues when subtitles aren’t synced and she can’t find any that are close.

Thanks!

Triggering “Analyze” on an item should start immediate voice activity detection.  
Make sure to be on the latest available server software version, as there were some fixes around that recently, AFAIR.

Ah. It seems this is episode or season based. You can’t do analyze on a Library or the Full show, or it won’t kick off the scan.

Thanks. Tedious, but it works.

You can use multi-selection to at least select all episodes of a whole season.
