wendyju, thanks for solving this problem!
I worked with the VS1033D board and it had extremely intermittent operation. If you moved a finger near it, it would emit static. But now I know it’s because the test pin was floating.
Another warning: CVDD is powered at 3.3V (same as IOVDD) but the VS1033D datasheet says 2.7V is the maximum. Not sure what the implications might be, but it’s definitely out of spec.
No public wish lists :(
