Dorico 4 lack of sound on playback

I seem unable to get any sound on playback of new material. It works on previous projects but not on the new. Any ideas? I had a similar problem when first using Dorico and sorted it with an engineer online. I have made similar checks to before but can’t find anything amiss. Thanks

Try re-applying one of the factory Playback Templates on a project that does not work.

Hi @donaldstuarthart , please create such non-sounding project again and while that project is open choose from the menu Help > Create Diagnostics Report and post the corresponding zip file here. Thanks

Thanks Ulf, but after rebooting my laptop several times everything seems to work!!!
