I cannot hear anyone on the outside bell there is no where for the sound

I have a brand new Eufy doorbell and I cannot hear the person at the door . I cannot find anything to increase the sound either on the device or on the App. Please let me know how I can turn it up. I am also seeing people on the pavement but not outside my door. I think it is slightly higher than 4 ft. will this make a big difference as my path is only about 7ft. long.

Under Doorbell Settings you should see an option for Audio Settings…
Which doorbell do you have?
Can you post a screenshot of the view the doorbell sees?
