While attempting to compile and build the Galagino package for a ESP32-2432S028R (aka, CYD or "Cheap Yellow Display") using the Arduino IDE under Windows 10, with the 2.0.14 version of the esp32 board library installed, the following error appears.

Compilation error: 'I2S_MODE_DAC_BUILT_IN' was not declared in this scope

Attempting the changes suggested by the compiler trigger additional errors to appear in the compiler log.

Is there a workaround for this issue on this model of device?

What board did you select in the IDE, what version of IDE and ESP32 BSP do you use?

It sounds like you selected a board/ESP variant that does not have a built-in DAC.
