Am I missing something:
I installed A4max
I installed Irig2 HD (was detected by W10 64)
Installed ASIO4all
Went into A4all setting and turned on Irig2
Ran Amp4
Went to setting set it to ASIO4all and set it to Irig2 (both inputs and outputs set)
Plugged in guitar and the light turns green when playing guitar.
Plugged in headphones (nothing)
Amp4 on the PC shows no input signal.
Checked the switch and it's set to FX (not thru).
Anything else I'm missing?
