Problem with SD_MMC Library - Won't compile on ESP32-WROOM-32U Module

[rwlangbe]

I added Audio.h to my project and added all the libraries, but now there is an issue with SD_MMC that refuses to build.
I'm using the ESP32-DevKitC Development Board ESP32-WROOM-32U Module.
I'm wondering if my Arduino version is too old, or if something else is missing.

This isn't a project issue directly. All of the files were not installed for the environment.
