Ah, OK, all drivers are up to date.
In
Preferences/Audio/Playback & Recording Asio is in the list of
Driver Mode but doesn't work. It tells me at start up:
There are no audio devices for the current driver model on your system and later:
...choose a different driver model and later:
The following tracks and buses are currently assigned to a silent hardware model...However, setting Driver Mode to WDM/KS does work and cures the display - sound synch.
So my next problem is to cure the latency between keyboard controller and Sonar which I'll get to later.
Thanks for your help.
