Hello, new iOS user here, but previously successful Windows user using the same iRig setup as described here (so I know my iRig works). I connected my iRig to my iPad Air (iOS 12.4.3). I can see the device and signal levels in MIDI Guitar when I play, but there is no output sound. “Output Channels” in MIDI Guitar is set to “IRIG HD 2 1 / IRIG HD 2 2” which is in fact the only available option. I have an amp connected to the amp output of the iRig and no sound comes out. If I use headphones with my iRig, I can hear output very very faintly if I play the onscreen keyboard tool in the app. What am I missing?
