Input keyboard not playing sound

Keyboard not playing Sound in Dorico. Have confirmed that dorico sound is active. Keyboard can input notes. But won’t play Notes while entering.

Dear Adrienre, welcome to the forum.

You confirm that sound is active in Dorico. Does that mean that you can play the notes that are entered (without sounding) with the keyboard and hear the sound ?
Could you please post diagnostic files, as per the guidelines? (help menu>Create diagnostic files, a zip file ends up on your desktop)

@adrienre ,
In the Dorico Preferences on the Play tab, scroll pretty much down until you find some MIDI options. There make sure that Enable MIDI Thru is ticked.
