Here's the problem, you do not want to specify input and output 
channels! Let jack decide and it will pick what the sound card supports. 
You are saying basically "I want a mono in and mono out" jack instance. 
The 1010 can't do that.

In the Setup dialog of qjackctl "Input Channels" and "Output Channels" 
should be "default".

And this is where it fails which is to be expected.

Don't specify the number of channels and it will (should?) work.
