no sound ur 22_ mac

After updating my mac to el capitan, i have troubles installing my audio interface steinberg ur22. Before it worked fine!

In my audio/midi configuration the steinberg ur 22 appears correctly. But when i select it as an audio output nothing happens, not on the headphones not trough the speakers.
When i open the driver configuration of steinberg i see just one tab, the “about” tab. Normally, its has 3 tabs… (steinberg ur22, ASIO, About)

some help please
