Aurora + Teensy 3.6 + SmartMatrix Shield v4 problems

… I commented out this:

 menuItemAudioPatterns.visible = enableAudioPatterns;
  menuItemAudioPatterns.playModeEnabled = true;
  menuItemAudioPatterns.paletteEnabled = true;
  menuItemPatterns.playModeEnabled = true;
  menuItemPatterns.paletteEnabled = true;
  menuItemAnimations.visible = sdAvailable && animations.imageCount > 0;
  menuItemAnimations.playModeEnabled = true;

and the display is working now - so does Aurora NEED the Audio thing connected otherwise it crashes or something?.. I’ve only got the IR connected because I’m in the UK and the Audio thing is enroute from America (couldn’t get one in the UK) so was building everything first.

Since commenting that out, I now have the word “Patterns” scrolling and a swirly pattern going on in the background, and everything seems to be working, the IR remote is working, I can change pattern etc I can get to the settings menu… so I have to conclude that it doesn’t work if the Audio board is not connected - is that right!?..

In fact, breaking it down further, it’s these 2 specific lines that prevent it from working:

//menuItemAudioPatterns.visible = enableAudioPatterns;
//menuItemAnimations.visible = sdAvailable && animations.imageCount > 0;

(I commented those 2 out to make it work hence the // at the front)
