Pro 4 Cameras Make loud, annoying audio sounds

[roundball]

Hoping the Arlo Community might be able to help.
Background:
I/T Tech Support all my life, use high performance laptop / network equipment, current software always kept up to date, etc.

1) Several years ago I bought / installed four Pro2 security cameras.
All 4 locations are within 25-35 feet of the base station.

Used them for a few years, no problems.

2) Then upgraded with four Pro3 cameras, installed in the same locations. Used them for a few years, no problems.

3) Then upgraded with four Pro4 cameras, installed in the same locations.

Have loud, annoying, audio static problems on all of them.

Uninstalled / reinstalled...no help.

Then set them up to run  off my WiFi instead of a base station...no help.

The only change that's occurred is removing solid performing Pro3 cameras and replacing them with new Pro4 cameras (with any / all Arlo updates).

( PS: two were so bad Amazon replaced them for me, and both replacements were noticeably better, although still not 100% correct ). 

I see this Pro4 audio related problem has also been experienced / reported by others the Internet.

If anyone here in the 'community' has any actual first hand knowledge of the cause / fix for this Pro4 audio problem, I'd appreciate learning about it.
Thanks

FWIW, I replied to update the case...thanking them for their honesty...that my detailed troubleshooting had proven beyond doubt it had to be a Pro4 camera problem.

PS:

I'm going to let it sit for a couple days now...then followup to my case# again, asking what the target fix projection is...ie: a Day?...a Week?...a Month?.....and see what they say.
