I recently purchased a Legacy 0-8-0 switcher new in the box. Set up the engine using the program switch and sucessfully loaded the module into my 990. It runs fine but when you hold down a speed icon on the CAB2, you hear a crackle like some dialog is going to happen, but it doesn't. I also sometimes randomly lose engine chuffing unless I touch the efx button. Then the chuffing resumes.
I get crew talk for startup, shutdown and tower/engineer buttons. Just not speed changes. Has anyone run into this? Is there anything I can try? Clear and reload the module perhaps?
