    It's been a looong day. But thanks to you all, it's working!

    The issue was that one of the output was bridged to ground under the chip. This seems to have the effect of shutting the IC.

    Aha!

    As I was testing the voltages, while the prototype was running, I was testing between GND and VCC and suddenly I got sound one one hear!

    Yes, it is because the teensy is soldered on the bottom side. So viewed from the top, we see its belly in transparent view.

    Then it is time to admit something! I have been foolish and directly sent a board to fab without testing the chip first.
    Definitely overestimated the plug'n play factor as said before!

    Seems like sensible advice! ;)

    So now I2S is outputting 32bit/channel audio data at 44.1khz? Thats massive! And that would explain why it would not work for me, since the limit is 24 bit audio...

    Thanks for the answer!

    Doesn't that contradict the information given on this page?

    >BCLK (ie SCLK), 1.41 MHz
    >LCRLK High=Left, Low=Right, 44.1 kHz

    So a 32x ratio? Or do I read that wrong?
