No sound in editor when notes are clicked

When i am in the editor, i no longer hear the notes when i click the mouse over notes on the screen, or when i move them. or when i use the chords feature.
When i click on the keyboard, or press PLAY using the transport, there is sound.

I rebooted the system and it’s the same thing.
How can i fix this please?

Click this button to enable this:

If you can’t find this button, click the gear icon to the top right and enable “Acoustic Feedback” to make it show up.

i see it. thanks
