Audio problems with update to iOS 16.1.1 on iPhone 12
I use my iPhone with an audio product (iRig Stomp) by IK Multimedia with their Amplitube App. The new iOS now has significant noise and distortion when connected via lightning cable/stereo earbud plug adapter.
Through a process of elimination, I attempted to isolate the issue:
Tested the adapter cable playing iTunes music w/ earbuds and adapter - no noise or distortion
Tested iRig box with my iPad (with older iOS) - no noise or distortion
Tested another similar competing App with the same hardware interface - This exhibited THE SAME NOISE & DISTORTION.
I didn't have this problem on my iPhone before the upgrade. It suggest that there is a bug in the audio processing for an iPhone 12 in the upgrade.
