@stschoen Ok, so I’ve tested based on what you pointed out, and you’re right (not that I doubted, just preface to the rest of my inquiry), it does work (OS X, anyway) with the ADC nodes for channel 1&2, however, that same setup does not work on iPad or iPhone.
The nearest conclusion I can come to is that A3 maybe doesn’t have any way to tell the OS now (since the Apple updates that changed a lot of audio issues we had been having previously) that the hardware microphone is needed, and so it is not activated.
This could be why the BT 4.0+ headphones have started working, since the issue I researched back in December 2018 seemed to have the microphone always on, and now it is off, and so now it is not trying to use a whole channel for input and only leaving a single channel for all output, even when no microphone was necessary, in previous use cases.
Do you have any suggestions about things I might be missing that could make the microphone trigger and make the ADC nodes for ch 1&2 for input work? I have attached the patch I just attempted to us on my iPad and iPhone just a few minutes ago for you or anyone else to take a look at, just in case I’ve wired something wrong. Your original version had just the single node, and so I sub’d in the ADC’s where I thought they would work the same. Thanks!
