DFPlayer - only returns -1 for myDFPlayer.read

Serial.println(myDFPlayer.readEQ());
Serial.println(myDFPlayer.readFileCounts());

None of the myDFPlayer.read commands return anything other than -1

Any clue why?

2020-09-11 04:33:25 Serial.println(myDFPlayer.readEQ());
Serial.println(myDFPlayer.readFileCounts());
Serial.println(myDFPlayer.readCurrentFileNumber()); //read current play file number
Serial.println(myDFPlayer.readFileCountsInFolder(2)); //read file counts in folder SD:/02

Returned this:
EQ=NORMAL
-1
-1
-1
