Using M-Track solo as an Interface, but I can't hear the signal

I have bought myself Cubase Elements and the M-Track Solo Interface and I have started a new project. I’ve installed the Asio for all Driver and Cubase also recognises my Interface, I can see that an Audiosignal is recorded and when I play it the Inspector shows me that the Audiosignal is beeing played. But I can not hear anything throug my Headphones, that are pluged inside the Interface. as output I have selected Audio Codec 2 and the driver Asio4all, but no signal is heard. Does anyone know this problem, or maybe even works with the same interface.

It’s generally a bad idea to use Asio4All when your interface has a dedicated ASIO driver.

Have you set up your Audio Connections?
