No recording on OS X 10.10.5 using quad-capture

I am trying to record from a yamaha mixer board through a Roland Quad-Capture into a macbook pro running OS X 10.10.5. I have selected the quad-capture as the input device on the mac settings, as well as in audacity, but nothing is recorded. I’m running Audacity 2.2.1

I also tried a couple of other options but Audacity seems only to record when using the built-in microphone, even if the other sources were selected (e.g. headphones with microphone).

Has anyone had this issue?
thanks for any help.

Does the device work in other applications (such as Garage Band) ?

yes it works in garage band fine
