Teensy 3.6 - CS42448 Codec Object Broken On New IDE - Wire Not Found Error

[grinch]

Hi, I need to revive an old project for Teensy 3.6, and with the new IDE version I am finding some audio objects that were previously working appear to be broken.

The error I am getting seems to be in regards to CS42448 codec control, it throws an error saying Wire can't be found. Does anyone know how to fix this?


Here is my stripped down test patch:

#include <Audio.h>

AudioSynthWaveformSine sine1;
AudioOutputTDM tdm1;
AudioControlCS42448 cs42448_1;

AudioConnection patchCord1(sine1, 0, tdm1, 0);

void setup() {
  AudioMemory(32);

  cs42448_1.enable();
  cs42448_1.volume(1.0);

  sine1.frequency(440);
  sine1.amplitude(0.5);
}

void loop() {
}

Here is the error:
