Answer 1

I have tested a lot of android devices,the following code works for me properly

Firstly, create a notificationBuilder, if your Build.Version is bigger than 26, please add a new channel.

  private val notificationBuilder: NotificationCompat.Builder by lazy {
        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.O) NotificationCompat.Builder(context) else {
            val manager = context.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
            val channelId = "MUSIC"
            val channelName = "音乐控制栏"
            val importance = NotificationManager.IMPORTANCE_MIN
            val channel = NotificationChannel(channelId, channelName, importance)

            manager.createNotificationChannel(channel)
            channel.enableLights(false)
            channel.vibrationPattern = longArrayOf(0L)
            channel.enableVibration(false)
            channel.setSound(null, null)
            NotificationCompat.Builder(context, channelId)
        }

    }

Secondly, init this notificationBuilder, and set sound null

   notificationBuilder.setDefaults(Notification.DEFAULT_LIGHTS ).setVibrate( longArrayOf(0L)).setSound(null)

Thirdly,if build.version is bigger than 24, please set its priority.

  if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            notificationBuilder.priority = NotificationManager.IMPORTANCE_MIN
        }

Hope that works for you.
