iRig Mic Studio can't adjust "level in" within apps

[lantz2cs]

I am using an iPad Pro running iOS 11.2.6. with an iRig Mic Studio. I am unable to adjust the microphone "level in" using either the Amplitube Acoustic or Garageband apps. This function used to work fine. The internal iPad micophone works fine and can be adjusted. I can adjust the gain on the mic itself but I should be able to adjust the level in within the apps. I tried my Blue Snowball USB mice via the Lightening camera adapter was able to adjust the "level in" just fine. So this appears to be specific to the iRig MIc Studio microphone. Anyone have any suggestions?
