Phone speaker works fine except with Ring Doorbell and Floodlight Camera

We have Ring Video Doorbell 2 and a Floodlight Camera with video. I get notifications fine and I can hear and see what is going on without a problem. I cannot speak to anyone though so that they can hear me. The apps have permission to access my speaker because I have quadruple checked. Everytime the front door rings and we are not home I have to grab my husband's phone to speak with whomever is there. Any ideas?
