Error when using sd library and audio library

I get this error when using sdfat library and teensy audio library:

but it works when i only use the sdfat library or audio library standalone.

Dangerous to call a file close to a library file.

What does the verbose library dependency graph look like? Use the project task Advanced → Verbose Build to output it and post it here.

I highly suspect its picking up some wrong library, or is including one of your files instead of the right libraries because of your self-created Sd code files.

I changed the name of Sd.h and now it works.
Thanks!
