I suddenly noticed after installing Silver Plate I somehow stopped to hear any engine sound when flying P-51B/C/D models. Just a complete silence... But everything's fine with Spitfire MkIX that uses Merlin also... And Early Mustangs (that have Alison) are O.K. also...
Can anyone please help?

P.S.: I use UI 1.0...

Thank you.
