Record on sound mode on Arlo wireless sys ?

[cherry-pie]

I noticed that there is a mode titles "ARMED-Motion and sound" for the wireless weatherproof cameras. I just wanted to confirm that the wireless cams dont have the capability to record on sound (i dont think they detect sound). is that correct? I'm assuming maybe this option is under my Wireless camera mode because i had added an Arlo Q and maybe in doing that it added the extra mode as well.. This mode was not there before.

The wireless cameras have no ability for audio at all.  Using that setting gets you nothing while it's quite useful for Q.
