Thinking of why it does not work currently: If you use an external sound card connected via USB, the computer sends and receives digital data through the device driver. As a windows machine as well as a Linux machine is able to work with the same external machine, it seems to be imaginable that the Jack I/O works against a USB connected sound card driver and the windows I/O too. So what's the problem? The problem is that each of the two computers waits to dectect the "connected device" to setup the right driver.  So no one of the both computers stands up and says: "Here I am, your Sound Service Providing Device". It is like a girl and a boy each sitting on their telephone and waiting for the call   ;-) . </div>
