TMRpcm not playing audio file

Other Hardware Audio

I am trying to play wav file using arduino UNO, catalex SD card and 8 ohm speaker

I am using TMRpcm library. My hardware is working fine (i checked separately). My code is compiling correctly but when i upload, the file isn't playing.

On serial monitor the output of --> Serial.println(tmrpcm.isPlaying());
is coming out to be 0

Here is my code-

#include <SD.h> // need to include the SD library
#define SD_ChipSelectPin 4 //using digital pin 4 on arduino nano 328
#include <TMRpcm.h> // also need to include this library...

TMRpcm tmrpcm;

void setup(){

tmrpcm.speakerPin = 9;

Serial.begin(9600);
if (!SD.begin(SD_ChipSelectPin)) {
Serial.println("SD fail");
return;
}
tmrpcm.play("WARRIOR.WAV");
Serial.println(tmrpcm.isPlaying());
}

void loop(){

}

Which code did you use testing the SD card?
Cable Select on pin D4?

Have you tried it with a known working wav file? You may have a wav file that is not within the specifications that the Arduino can handle.
