Expo AV audio not playing on iOS/ iPhone

I have used Expo AV and developed a screen in my app to play audio files fetched from my server URI. It works fine on Android, but doesn’t play anything on iPhone When I play a button to play the audio which loads and plays the file soundObject.loadAsync({ uri: this.state.file }); soundObject.playAsync();

it returns an error :This media format is not supported. - The AVPlayerItem instance has failed with the error code -11828 and domain “AVFoundationErrorDomain”.

Here is my code that loads and plays the audio :

async loadAudio() {
soundObject = new Audio.Sound();
try {
await soundObject.loadAsync({ uri: this.state.file });
console.log("File loaded: " + this.state.file);
} catch (error) {

async playAudio() {
if (!this.state.isPlayingAudio) {
try {
  await soundObject.playAsync();
} catch (error) {

  else {

I have tried changing the audio format to m4a, wav, caf while recording and fetching the file but that did not help. Any suggestions/ fixes, please? Thanks in advance
