no volume control with UR824

Hi guys,

maybe someone can help me, i have switched from motu 828 to an UR824 and i must say i am disappointed on how badly the device integrates with max osx yosemite.
there is no system white volume control (greyed out) and everytime i restart the mac
i have to reselect the audio output device in the system preferences as it will just default back to internal speakers
is there anyway to fix this?
