I am using AVAudioSession and I am activating in my browser on launch. I have set category AVAudioSessionCategoryPlayback. I have not set any category options. I want audio to be played even in background. If I don't use AVAudioSession then I will not able to play audio even in background. I don't want my app's audio to mix up with iTunes song and play both simultaneously. As its browser application, we don't need audioSession always but when playing audio alone. Similar to how mobile Safari handles audio when iTunes music is on. I saw other category options and modes of AVAudioSession. Kindly give any suggestions for the same.
Here I fixed this,
Xcode 10.x Swift 4
Add the following code in your AppDelegate.swift
func application(_ application: UIApplication, willFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey : Any]? = nil) -> Bool {
do {
try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback, mode: AVAudioSessionModeDefault, options: [.mixWithOthers, .allowAirPlay])
print("Playback OK")
try AVAudioSession.sharedInstance().setActive(true)
print("Session is Active")
} catch {
print(error)
}
return true
}
Note: - Please configure options as required. E.g to stop a background audio while a video file being played add
options: [.allowAirPlay, .defaultToSpeaker]
And don't forget to enable audio and airplay in Background mode

I'm making an iOS game with Swift and trying to play system sounds when the iPhone is silenced so that you can hear sound effects regardless of volume mode. The code to play the sound is:
AudioServicesPlaySystemSound(1000)
This works fine when the iPhone has the volume rocker unmuted; however, if the phone is silenced, nothing plays. If I change this to:
AudioServicesPlayAlarmSound(1000)
I get vibrating on silent mode but not the audio. I've seen examples of how to setup the AppDelegate to change the audio mode like the following:
class AppDelegate: NSObject, UIApplicationDelegate {
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
do {
try AVAudioSession.sharedInstance().setCategory(AVAudioSession.Category.playback, options: AVAudioSession.CategoryOptions.mixWithOthers)
try AVAudioSession.sharedInstance().setActive(true)
} catch {
#if DEBUG
print("ERROR: Cannot play music in background: \"\(error)\"")
#endif
}
return true
}
}
However, I'm using iOS 15 and AppDelegate isn't really necessary anymore. What's a modern way I can play system sounds regardless of the volume state in my game? No other answers on the site worked for me.
We have functionality for background recording in app.
It is working fine when app in background mode but it is stop when we open other app and play sound in it.How can we continue recording even without stop recording when other app play sound.
Note: When Recording start at that time out app in background mode.
Call this method in appDelegate,
func audioSessionSettings() {
do {
try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryRecord, with: AVAudioSessionCategoryOptions.mixWithOthers)
try AVAudioSession.sharedInstance().setActive(true)
} catch let error {
print(error.localizedDescription)
}
}
I am working on music app.
Here is the case which I want to fix:
I open AppleMusic app > play something > open my app > click play > music does not play. Why and how to fix it?
I use that but still does not work
func applicationDidBecomeActive(_ application: UIApplication) {
// Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
do {
try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
try AVAudioSession.sharedInstance().setActive(true)
} catch let error as NSError {
print(error.localizedDescription)
}
UIApplication.shared.beginReceivingRemoteControlEvents()
}
This code shows you if another app is playing sound in the backgroud
var otherAudioPlaying = AVAudioSession.sharedInstance().isOtherAudioPlaying
If so, try this:
AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryAmbient, error: nil)
I have an app that needs to have:
Background music playing while using the app (eg. spotify)
Background music playing while watching movie from AVPlayer
Stop the music when recording a video
Like Snapchat, the camera-viewcontroller is part of a "swipeview" and therefore always on.
However, when opening and closing the app, the music makes a short "crack" noise/sound that ruins the music.
I recorded it here:
https://soundcloud.com/morten-stulen/hacky-sound-ios
(3 occurrences)
I use these settings for changing the AVAudiosession in the appdelegate didFinishLaunchingWithOptions:
do {
try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayAndRecord,withOptions:
[AVAudioSessionCategoryOptions.MixWithOthers,
AVAudioSessionCategoryOptions.DefaultToSpeaker])
try AVAudioSession.sharedInstance().setActive(true)
} catch {
print("error")
}
I use the LLSimpleCamera control for video recording and I've set the session there to:
_session.automaticallyConfiguresApplicationAudioSession = NO;
It seems others have the same problem with other camera libraries as well:
https://github.com/rFlex/SCRecorder/issues/127
https://github.com/rFlex/SCRecorder/issues/224
This guy removed the audioDeviceInput, but I kinda need that for recording video.
https://github.com/omergul123/LLSimpleCamera/issues/48
I also tried with Apple's code "AvCam", and I still have the same issue. How does Snapchat do this?!
Any help would be greatly appreciated, and I'll gladly provide more info or code!
I do something similar to what you're wanting, but without the camera aspect, but I think this will do what you want. My app allows background audio that will mix with non-fullscreen video/audio. When the user plays an audio file or a full screen video file, I stop the background audio completely.
The reason I do SoloAmbient then Playback is because I allow my audio to be played in the background when the device is locked. Going SoloAmbient will stop all background music playing and then switching to Playback lets my audio play in the app as well as in the background.
This is why you see a call to a method that sets the lock screen information in the Unload method. In this case, it is nulling it out so that there is no lock screen info.
In AppDelegate.swift
//MARK: Audio Session Mixing
func allowBackgroundAudio()
{
do {
try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback, withOptions: .MixWithOthers)
} catch {
NSLog("AVAudioSession SetCategory - Playback:MixWithOthers failed")
}
}
func preventBackgroundAudio()
{
do {
//Ask for Solo Ambient to prevent any background audio playing, then change to normal Playback so we can play while locked
try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategorySoloAmbient)
try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
} catch {
NSLog("AVAudioSession SetCategory - SoloAmbient failed")
}
}
When I want to stop background audio, for example when playing an audio track that should be alone, I do the following:
In MyAudioPlayer.swift
func playUrl(url: NSURL?, backgroundImageUrl: NSURL?, title: String, subtitle: String)
{
ForgeHelper.appDelegate().preventBackgroundAudio()
if _mediaPlayer == nil {
self._mediaPlayer = MediaPlayer()
_mediaPlayer!.delegate = self
}
//... Code removed for brevity
}
And when I'm done with my media playing, I do this:
private func unloadMediaPlayer()
{
if _mediaPlayer != nil {
_mediaPlayer!.unload()
self._mediaPlayer = nil
}
_controlView.updateForProgress(0, duration: 0, animate: false)
ForgeHelper.appDelegate().allowBackgroundAudio()
setLockScreenInfo()
}
Hope this helps you out!
I am using an AVAudioEngine object, that has many AVAudioPlayerNodes attached to it. The audio all works fine, except it stops any audio that the iPhone is playing in the background (i. e. from iTunes or another music app).
When my app is opened, it stops any other background audio. Is there a way to allow background audio to continue to play? Even when my app is using AVAudioPlayerNodes to play audio itself?
Music App has it's own audioSession, that makes audio engine stops, i had that problem too, please restart after music app.
func stepB_startEngine(){
if engine.running == false {
do { try engine.start() }
catch let error {
print(error)
}
}
}
setup audioSettion also:
func setUpAudioSession(){
do {
try AVAudioSession.sharedInstance().setCategory(.ambient, options: .mixWithOthers)
try AVAudioSession.sharedInstance().setActive(true, options: .notifyOthersOnDeactivation)
} catch let error {
print(error)
}
}
