Blackmagic UltraStudio Mini Recorder Audio issues

Using a 2013 iMac (10.9.4) and Boinx (1.9.9 17091) When choosing the Blackmagic UltraStudio Mini Recorder as the audio input, I get bad audio distortion. Any ideas?

When you open BlackMagic Media Express and record from there, is the audio intact in the recording?
