And short addition: pin 14 of the expand header is not a Ground, as it shows in the table 3, but GPIO 5 (at least in both Cirrus Logic ACs, which I was happy to get today).
It looks likethere is a minorerror in the manual (page 14, last four rows of the table 3 "GPIO signal definitions", column 5) - incorrect GPIOs (in all rows "GPIO3", and not "6, 12,16, 26").
