While I had no problem on my laptop with the iRig HD X,  I wasn't so fortunate with the Komplete Audio 1 to my Main PC.  I can see there is input from my guitar to the input, but nothing on the output.  Nothing showing in Guitar Rig 7 either.  But as I said no problem on laptop with the iRig HD x.  So the only thing different is the Komplete Audio which I did set as the output in the software and in Windows.
