react-native-sound: Strange: Local files fail to load, but only for previously downloaded file

Hi all,

I’m using react-native-sound to play files downloaded with react-native-fetch-blob and stored in local storage. But strangely, while I’m able to immediately play the file right after it’s downloaded and stored, the file fails to load after I close the app and restart again. Here’s a screenshot of the console: Section 4 is freshly downloaded and I’m able to play it, while Section 5 was a file downloaded in the previous run of the app. As you can see, the file path structure is exactly the same. So I’m rather baffled by why this is happening!

Here’s the part of my code that handles file loading and playing:

let Playing

function setCurrentPlaySession(section) {
  console.log('set play session to: ', section.section_id)
return {
  type: types.PLAYING,
  payload: section
}
}

export function playFile(sectionInfo) {
  return (dispatch) => {
    Playing = new Sound(sectionInfo.filePath,'', error => {
      if(error) {
        console.log(`Is section ${sectionInfo.section.section_id} loaded? ${Playing.isLoaded()}`)
        console.log(`failed to load section: ${sectionInfo.section.section_id}`, sectionInfo.filePath, error)
        return
      }
      dispatch(getPlayDuration(Playing.getDuration()))
      console.log(`section ${sectionInfo.section.section_id} is playing from ${sectionInfo.filePath}`)
      dispatch(setCurrentPlaySession(sectionInfo.section))
      if(sectionInfo.currentProgress) {
        Playing.setCurrentTime(sectionInfo.currentProgress)
      }
      Playing.play((success) => {
        console.log('finished playing ')
      })
    })

  }
}

Any insights on this would be much appreciated. Thanks!

This is only on IOS simulator. I’m using react-native 0.41 and react-native-sound 0.9.

Oh, and I also tried rolling back to v 0.8 of the library, as suggested by one response in a similar open issue before this one. It didn’t help. Playing audio is the most key functionality of my app. So I’m rather frustrated right now. Looking into other libraries. But I really like this one, when it works.
