Last night at 1:45 am I was awakened to the very loud voice of a woman coming from my living room. I ran in there to find out it was a newscaster from the BBC booming from one of our speakers. Nothing was turned on! Thinking it was coming from our Sonos System which has broadcast options from all over the world, I grabbed my phone looking for the Sonos App to turn it off. It told me to reinstall. So I went to my laptop and tried the Sonos App there, it wanted to update, which I did. After that I looked through and nothing was turned on. I removed a radio station. She still kept shouting! I disconnected the Sonos speaker, no help. I realized it was coming from the other large speaker next to the DVD player. I tried to find a wire to turn off that speaker. Suddenly it shut itself off! Sudden quiet at 2:15 a.m. Husband slept through it all! I still cannot understand what happened nor can he!!
