我有自定义声音的推送通知，直到 android 10。从 Android 11 开始，当通知显示为下拉样式时，附加到通知通道的声音停止播放。当它显示为全屏活动时，它会起作用。

    String channelName = "Channel High"
        NotificationChannel channel = new NotificationChannel(channelId, channelName, NotificationManager.IMPORTANCE_HIGH);
        channel.setDescription("My custom sound");
        channel.setLockscreenVisibility(Notification.VISIBILITY_PUBLIC);

        AudioAttributes.Builder builder = new AudioAttributes.Builder();
        builder.setUsage(AudioAttributes.USAGE_NOTIFICATION);
    String basePath = ContentResolver.SCHEME_ANDROID_RESOURCE + "://" + getPackageName() + "/" + R.raw.alarm_sound);
    Uri alarmSound = Uri.parse(basePath); …
