Is AudioSourceSDFAT capable of using SdFat in SD_FAT_TYPE 3 mode (Fat16/Fat32/ExFat)?

I'm trying to go through all the examples to get my program to work with AudioSourceSDFAT, but I want to get the code to work with the AudioPlayer class using AudioSourceSDFAT in what appears to be an oddball configuration.

Currently, I can get it to work with my FAT32 formatted SDCard, but I want to use a bigger SD card in its place, formatted as ExFAT, with the option to still use a FAT32-formatted SD card.

currently, I can make the example player-sd_m4a-audiokit.ino somewhat work as a baseline (using I2SStream instead), so my hardware works. I get audio playback.

But All the SdFat examples in your repo have been using it in the FAT32 mode, using a similar method to the latest example you uploaded (player-vector_sdfat-audiokit.ino) but it seems to be using SdFat in Fat32 mode, using SdFat and File32 classes. From my understanding of the documentation of SdFat, I need to use SdFs sd; and FsFile instead if I want to support FAT16/FAT32/ExFAT at the same time.

Is this a supported configuration?

I haven't had a chance to try for myself and compile the player-vector_sdfat-audiokit.ino example using SdFs and FSFile instead, but I guess I will try and see if I can get it to work when I get back to my developer board.

If you check the class documentation for AudioSourceSDFAT you can see that it is a template class (that uses SdFat32 and File32 automatically if nothing has been specified) so just provide your desired FS and File class!

AudioSourceSDFAT<SdFs, FSFile> source;

But I suggest that you test your desired functionality outside of the AudioTools first...

Perfect! I saw the class description page of it, and was slightly confused by the parameters (was focused mostly on the Public member classes rather than the parameters described down lower on the page [I'm also slightly new to C/C++]). I appreciate it man! Once I get the rest of my code working around it, I'll be sure to upload my sketch for someone else to use!
