digging a bit deeper i've found thet the bug is inside af_resampel.c,
it gets the right len but returns bad.

it's probably caused by 16bit arith used there!??

  uint16_t              len   = 0;              // Number of input samples

etc

why is int16 used everywhere ?
buffers may be (and are) larger than 65535.
