Version 5.11A of the Hyperion Pro driver has been released. Issues with audio and/or video playback have been reported. They are caused by a problem with the V-RAID driver. A new V-RAID driver has now been released, v5.50b. If you want to use the Hyperion Pro 5.11A drivers you can download them from here but we recommend installing the V-RAID v5.50b drivers as well.
