If anyone else sees a distortion issue, first try turning off Volume Boost in DPS Preferences. If bad sound continues, please let us know some details of your system so we can re-create the issue and make an official fix. Thanks!
As xaqmusic stated, So far we have had just a few reports of distortion. 2 users have stated that turning off the volume boost has resolved their issue. Still chasing another down. If anyone is experiencing this please reply with details of your device (Macbook, Mac Mini, Mac Air, Harmon Kardon Speakers, etc), what DPS profile is used, etc. Thanks!
