    SOLVED:
    Pedvide, it maybe helpful to add a tip to the Audio support, users may need to manually edit the Audio library and disable internal reference.

    Hi Ben,

    I didn't check this thoroughly, but to start with it looks like you need to declare audio memory in setup(). I pulled this from the Peak example, but you might need more than 4 blocks.

    I've put a PM out to Pedro, but presently even " #include <ADC.h> " will break the AudioInputAnalog object/ADC configuration.
    I'll keep everyone updated, but presently it looks like...
