I have an IRig pro (not the I/O, which is newer). It was my main interface until I bought the AXE I/O and I've kept it for portable playing situations.
I worked on my desktop with the AXE and took my laptop and IRig on the road to play, and... no sound. Couldn't make it work in AT 5 or 4.
I then went home and thought maybe it was a cable issue as I was using the cable I use with the AXE. Used a regular instrument, cable tweaked some settings, and it worked. I was going to play again, decided to test it first so I wouldn't get embarrassed again, tweaking it for 2 hours, no sound. Like when it didn't work last time, it doesn't appear to get the input. The blue light is on showing it has power, but the green light never goes on to show that there is sound.
Any ideas?
