AWFUL Audio on ONE Camera, but not the other!

Good evening. I have searched this topic and have not found anything that has fixed my issue.I have a Ring Doorbell 2, an original stick up cam and a next gen stick up cam.The ONLY one that has usable audio (from my phone to the device) is the next gen camera.Here are the stats for the cameras. Just by looking at things, it looks like the firmware version is my problem. Has anybody found a fix? This is driving me nuts!DoorbellRSSI -42Firmware 2.0.59CLOSEST to wifiAUDIO AWFULOriginal Stick Up CameraRSSI -59Firmware 2.0.592nd closest to WIFIAUDIO AWFULNew Stick Up CameraRSSI -53Firmware cam 1.4.126Farthest from WIFI routerAudio works awesome.Any help that somebody could provide would be beyond appreciated.Thanks and stay healthy!
