AdaFruit Audio Library doesn't support Metro M4 Airlift?

[jluros]

I'm trying to get the Adafruit audio library working with my Metro M4 Express Airlift Lite. In two examples I've tried, WavFilePlayer and sketch_jun13a, I'm getting the same error:

Audio_-_Adafruit_Fork/input_adcs.cpp:161:2: error: #error The Adafruit audio library is compatible with M4 parts only
  161 | #error The Adafruit audio library is compatible with M4 parts only

Beginning on Line 122 in input_adcs.cpp, the compiler goes through if/elif/else statements to detect the board variant (_VARIANT_ITSYBITSY_M4_, _VARIANT_FEATHER_M4_, etc.), and gets to the end without matching any of the supported boards.

I think the board variant for the Metro M4 Express Airlift Lite is "ADAFRUIT_METRO_M4_AIRLIFT_LITE", but the compiler obviously doesn't think that _VARIANT_METRO_M4 on line 138-143 is true, otherwise the following would be called and the error "The Adafruit audio library is compatible with M4 parts only" on line 161 wouldn't get triggered:

#elif defined(_VARIANT_METRO_M4_)
   switch (pin1)
   {
      case PIN_A4: ADC1Channel = ADC_Channel0; break;
      case PIN_A5: ADC1Channel = ADC_Channel1; break;
   }

Any help would be greatly appreciated.

Ummm, you might be better asking on the Adafruit forums.

I did, but also posted here in case someone might have dealt with the same or a similar issue. Sorry, I’m pretty new to the Arduino world, but have built up a few Raspberry Pi kits, and have some experience with electronics and soldering.

Have had similar (non)response on their forum - it is nothing like the focus and attention here. Too many variants of hardware ( and software split : Arduino and python ) and in this case they ported the PJRC Audio library on some devices..

I think the board variant for the Metro M4 Express Airlift Lite is "ADAFRUIT_METRO_M4_AIRLIFT_LITE", but the compiler obviously doesn't think that _VARIANT_METRO_M4 on line 138-143 is true,

Then force the _VARIANT_METRO_M4 to be defined in the compiler preferences for that board?
