Thanks again for your continued support. Please consider the following responses to your questions.
Please note that the temporary solution you posed last week had intermittent success. It seemed that even loading a single piano project prior to the main project began to not play back any sound.
So here are some things we kindly ask you to check:
1.) Is it really only ever after a reboot? What if you close Dorico and launch it again, does it happen then as well?
2.)What if you exchange BBCSO with HALion Sonic (e.g. choose the HSO template instead), save that and reboot, is it also mute then?
See next question…I removed Halion but have VSL Synchroinized template instead
3.) If you have a project with just a single instance of BBCSO, does it also happen?
I proceeded to do an experiment…
Successful loads after reboot:
Test 1. Create Classical Template With BBC 35% Utilization - play sounds
Test 2. Reboot - Classical Template With BBC adding Abbey Road 37% Utilization - play sounds
Test 3. Reboot - Classical Template With BBC adding Abbey Road adding pianteq6 piano 40% Utilization- play sounds
Test 4. Reboot - Classical Template With BBC adding Abbey Road adding pianteq6 piano adding Spitfire Organ (Kontakt) 41% Utilization- play sounds
Test 5. Reboot - Classical Template With BBC adding Abbey Road adding pianteq6 piano adding Spitfire Organ (Kontakt) Add Brass 8341 Template 49% Utilization - play sounds
Failed loads after reboot:
Test 6. Reboot - Classical Template With BBC adding Abbey Road adding pianteq6 piano adding Spitfire Organ (Kontakt) Add Brass 8341 Template 49% Utilization - No Sounds - Closed Project but exported flow before loading next test scenario
Test 7. Successful load while Still using same instance of Dorico (loaded Flow from previous fail with VSL Orch Sounds as default playback template) (I removed HSO unfortunately from my machine) 18% Utilization - Plays Sounds
Test 8. Reboot and Successful load with VSL Orch Sounds + FLOW project from previous test 18% Utilization - Plays Sounds
Closed that project and in same instance of Dorico reopened Project that failed in test 6 (BBC with 49% utilization) - No sound
4.) How long did you wait for the project to load? Just until the play button becomes green? It might be that BBCSO just needs longer to load the sounds. Maybe if you leave it for a couple of minutes, does it then play?
I always wait until the Windows Task Manager levels out in the Memory/RAM view before triggering a sound. I try not to go beyond 70-80% of RAM utilization. Even after allowing the sounds to load they fail to trigger in Dorico although you can here them when pulling up an instance of the VST in the PLAY tab.
