Playback and score following at widely different tempi

A project I am working on in Dorico plays back at approximately half the speed of the tempo indication and also half the speed of the score following. I can’t find anything related in the online manual or forum and wonder if there is a remedy.

Check that the soundcards samplerate matches Dorico’s… another app may have changed it…?

There are known problems in 1.0.30 where the display can go out of sync if you have a sample rate of 48k. These are fixed in 1.1. Switching to 44.1 should also fix it.

Thanks to both - problem solved.
