Would like to turn OFF automatic closed captioning
I have Sonoma 14.4.1 and Safari 17.4.1. I watch a lot of tutorial videos. Every video I start playing has closed captioning already turned on, and I must deactivate it for the video. I have checked Settings, Accessibility, and Captions, and three different captioning styles exist. Each of these 'styles works, but I can't delete any of them. There is a button that is turned off called "Prefer closed captions and SDH". I don't know what SDH is. I have tried toggling this on and off, but I don't see a difference. I think it's great to have the option, but I would like to turn OFF this particular option.
Is there a way?
