how to set AVAudio session correctly

Forums > Swift

I have background music playing but when other sounds are activated it stops. I am sure it is to do with AVAudiosession. I have tried a few different settings but nothing seems to work.

I have a function button to start and stop the background music. The code for both is below.

class MusicPlayer {
static let shared = MusicPlayer()

func startBackgroundMusic() {
if let bundle = Bundle.main.path(forResource: "playlistbj", ofType: "mp3") {
  let backgroundMusic = NSURL(fileURLWithPath: bundle)
    do {
        audioPlayer = try AVAudioPlayer(contentsOf: backgroundMusic as URL)
        guard let audioPlayer = audioPlayer else {return}
        audioPlayer.numberOfLoops = -1
    } catch {

    if #available(iOS 10.0, *) {
        try AVAudioSession.sharedInstance().setCategory(.playback, mode: .default, options: [.mixWithOthers])
    } else {
        // Fallback on earlier versions
    print("Playback ok")
    try AVAudioSession.sharedInstance().setActive(true)
    print("session is active")

    guard let player = audioPlayer else{
catch {
    print ("oops")
