play audio using sdfat library

Can I use the sdfat library to play audio through SD Card?

Because when I use the sdfat library with TMRpcm library at the same form, it causes many problems

Not quite sure what you mean by 'play audio through SD Card' ?

Do you mean that you have a file on the SD, and you somehow want an Arduino to turn it into music ?

Thank you for caring, yes, this is what I mean
