The recently released Interim Report report suggests that the CVR may have been inadvertently deactivated in the past (The previous May) by having tripped the inertial switch perhaps on a hard landing. And that this did not come to anyone's attention as a check of the CVR function is not on the checklist used so the CVR remained switched off.
