How to convert the signal from the linein of the ASIO input to line-in, but simple?

Question

System administration

The essence of the problem:
Windows (8 RP). There is an external usb-audio card. A guitar is included in its line input.
The problem is that the signal from the line input normally goes only through asio.
There is silence in the standard line input of the card.
I want to play Rocksmith, which asio does not understand, but understands a simple wdm line-in.
Now it works in a workaround like this: fruity loops is launched, asio link is selected as a driver, in the mixer - input goes straight to the output of the external sound without plug-ins, asio link from the out of the external sound creates a virtual line-in, in which the signal already sounds normal and the game works. The problem is that the trial driver completely cuts the sound for 5 seconds once a minute, the delay is noticeable, although not large, noise and a lot of hemorrhoids with the launch ...
If you know a way how you can either make the line input work without these extra gestures, or simplify the circuit (I suspect virtual cables can help, but I haven’t figured out the settings myself) - write your thoughts, I will be grateful.
