Sudden playback problems

All of a sudden I have a quite long delay when playing back scores using Noteperformer. The green caret is around two bars ahead of what’s playing, very annoying.
This behaviour is new. Started today. Anyone who experienced this? Any solution? Any settings that I need to check?
I have Dorico 2.1.10 and Noteperformer 3.1

Try going to Edit > Device Setup and changing the sample rate, then changing it back again.

Thanks Daniel! That worked!!
