Intermittent Bluetooth Audio Issues with Contour

A few months ago we began experiencing loss of Bluetooth Audio on Contour.  I use bluetooth headphones at night to avoid keeping my wife awake.  I purchased new headphones from Cox in the event the issue was with my headphones.  Issue still happens randomly.  I have to reset the contour box multiple times and reconnect to make it work.  Sometimes that will work, other time I give up and watch on my iPad without problems.  This seems to be isolated to Bluetooth on the Contour Box.  It was stable for the longest time which makes me think a firmware or software update may be the issue.  Tech Support was going to ship me a new Contour Box - but that never happened.  Any ideas?
