I am setting up Ableton for the first time.  The RME is working fine in Sonar and all system sounds come through the RME just fine.  I selected ASIO and then RME and set up my inputs and outputs in preferences but the test sound will not work. 

The test sound works fine if I switch to my laptop's onboard sound card.

RME Fireface 800
