@WyzeChao here is my Wyze-Cracker Scientific V3 vs. V2 Audio test. Highly scientific as I used shipping tape to mount V2 next to V3.
There is a difference between the 2 cameras and the V2 has better audio but both do get the audio.
You can even hear my remote alarm keypad announcing the door being opened for further audio…
V2 event below:
V3 event below:
The V3 Wyze Cam Audio definitely could use some improvement but your hardware may be the limiting factor here as maybe the vendors that make the cams you sell are 2 different Chinese manufacturers? - Or some one has chosen a cheaper microphone and audio I.C. chip / audio processor?

A future product from Wyze - “The Wyze Crapper” Bidet
New upcoming Wyze product nicknamed “The Wyze-Crapper” a Wyze WiFi Bidet although a firmware bug might scare the crap out of me.
