  Hi,

  I don't know if you are still interested, but I played around with audio playback and found that the buffer passed to the callback seemed to be the wrong one. The following code shows how I refill the buffers for click-free audio :-

  w.on("buffer", function(buf) {
      if (w.currentBuffer == 0)
      {
        w.buffer2.set( /* new data */ );
      }
      else
      {
        w.buffer.set(/* new data */ );
      }
    }
  });
  

  Also, if you want to speed up the SD card access then you can indeed increase the SPI rate :-

  SPI2.setup({mosi:B15, miso:B14, sck:B13,baud:20000000});

  I hope that is useful.
