Thanks for the response.  That's not it.  I don't have a bluetooth unit and the function on my android phone for bluetooth is turned off.  My landlord doesn't have it that I know of but the sound is still there even when she's not home and has her cell phone with her.  I'll have to see if I can figure out how to upload a video.
