Sorry, my fault. I was assuming RadioBoss Cloud from your post... I shouldn't reply when I'm not fully awake.actucast said:If I'm in options, if I use object navigation, nvda moves to the next slider without telling me which slider it is.
I use the latest version of radioboss ...

Yes, the option controls are not fully accessible, not only the sliders. Some input fields are also guesswork for screen reader users. You can try to use flat review mode in NVDA, but this sometimes isn't accurate in finding the current control.
