AKplayer和AKAudioPlayer插入式耳机将在iPhone6s iPhone8s上静音

Question

在iPhone6s上，AKplayer和AKAudioPlayer插入式耳机静音，而iPhone8s AKplayer仍在播放。 我已经尝试了很多方法，但都没有成功

这是我的代码：

do {

    AKSettings.playbackWhileMuted = true;
    try AKSettings.setSession(category: .playback, with: .mixWithOthers)

    let backFile = Bundle.main.path(forResource: "1", ofType: "mp3")!
    let backUrl = URL.init(string: backFile)!
    backPlayer = AKPlayer.init(url: backUrl)
    AudioKit.output = backPlayer
    do {
        try AudioKit.start()
    } catch {
        print("AudioKit.start()失败")
    }

} catch {
    AKLog("Could not set session category.")
}
