No sound in Dorico 4

Hi @Janet_Baldacci ,
thanks for the data, unfortunately it still does not give me a real picture of what is happening on your machine. There are 2 crash files of the audio engine contained, but both have a file size of zero bytes, so these files certainly are not helpful then.
So we have to start with the basics again, please have a look at this thread and go through the steps and tell me where it starts diverting from the expected behaviour. Thanks
