I have the same complaint about delay between the sounds coming out of the Keypad in the hallway vs the Base Station in the adjacent room, except in my case the delay is less than 1 second, but still annoying. For now I just turned the volume down on the audible alerts on the Base Station but I’d prefer to keep them turned up for louder overall volume of verbal alerts and chimes.
btw a while back I posted a feature request to add a slider in the app allowing you to tweak the Base Station’s audio output delay. I hope Ring can add this feature in a firmware update.
