I have two of these cameras. One white that I've had for about two months, and a new black one. I never had a problem getting alarm sounds to play on the white one with Blue Iris, but when I got the black one, configured the same way, it just wouldn't allow me to play an alarm through the camera speaker. I eventually deleted my white camera from BI and figured I would recreate it and see if the camera speaker worked for alarm, and now it won't work either. I have been through every setting I can find and no luck, I can't play an alarm sound through either camera now.
Any ideas?
