Its an Asus Xonar U1 USB audio jobbie. Its using the line-in so no point in selecting something else! Maybe there are very few people using USB audio. You'll note the issue is a real one from the video I posted I guess.
On your website you state 'Documentation for the Windows DLL used by our standalone application and plugins is also available to allow you to create your own application or integrate the radio with other software.' is this still the case, and can I get these docs and i'll knock up my own plug-in.
