Waking up to your favorite music is always nice, but it becomes rather annoying when you can'' turn off said alarm. From a report on Engadget: That's exactly what Sonos users are experiencing and one editor on our staff dealt with the headache first hand. In fact, the alarms are also going off a day early, meaning Saturday wake-up calls were playing this morning. The company posted in its forums this morning that it's looking into the issue and recommends users delete all alarms from the Sonos app for right now. As our editor and many others have experienced, deleting the alarms is the only way to make them stop. We'll have to wait for official word on the cause, but alarms set for December 31st going off on December 30th could be a New Year's or Leap Year bug. Back in 2011, Apple had a problem with iPhone alarms not working correctly on January 1st.
