I have a MacBook Pro 15 with TB. The problem is that Siri does not hear me when clicking on the icon in the navigation bar. I check the settings of my microphone and it looks good. I have macOS Mojave 10.14.5.
But when I click on the icon as I say, nothing happens. It does not show the small color waves observed when Siri listens to you. I'm trying to restart the computer but does not work.
