Two Camera Setting Questions

1) I received a pop-up in the app about sound is now available with the cameras.  It said I could configure this anytime in camera settings.  But I cannot find it in my app or the web portal.  Anyone figure this one out?

2) What I really need is a way to turn off the infrared on some of the cameras.  I have some looking out through windows, and when the infrared goes on all I get is a reflection.  Surely there is a setting to turn off the infrared.  Every IP cam on the maket has that.  Anyone know how?
