I have mbox 2 mini. When I select WDM drivers, I hear no sound at all. When I select ASIO drivers, I hear the sound alright but the playback cursor does not move though the track plays back. Can anybody help?

I have the same interface and it works fine.
 
Need more info - what driver version and firmware version?
 
Also, what are your computer specs, operating system and Sonar version?
 
Does the audio interface work when you are using iTunes, or YouTube?
 
One final question, do you have it plugged into a USB 2.0 port (as opposed to USB 3.0)?

Hi Dave,
 
Thanks for the reply! I finally changed to Focusrite 6i6 and it's working fine now! I'll use the mbox 2 mini with my mac!

Glad you got something working - I will probably upgrade my interface in the not too distance future myself.
