Add sound when a confirmation is needed

Sound whenever agent needs input from user and on errors

The sound is helpful with longer running requests however I’m now find myself in situations when I wait for the sound just to find the agent looking for a confirmation on file delete action or (rarely) connection error. Let’s have sounds anytime user’s attention is required.
