自定义通知声音不播放，默认播放每次播放

Question

我知道这个问题已经存在，我向你保证我已经阅读了答案，没有人帮助过我，因为我的案例是针对RingtonePreference的结果

以下是我用于推送通知接收器服务的代码... 我从RingtonePreference获取铃声首选项，当您在Android Studio中创建设置活动时，默认情况下会创建该铃声首选项。

铃声的偏好会吐出这样的URI：
content://media/internal/audio/media/38

问题在于，无论用户在首选项中选择了什么声音，即使我直接从此选择中解析URI，每次都会播放手机的默认声音！

非常感谢任何帮助。

仅供参考：我还尝试将声音设置为null，然后使用此代码段手动播放铃声：

Ringtone ringtone = RingtoneManager.getRingtone(preference.getContext(), Uri.parse(stringValue)); 
ringtone.play();

但是发生的事情是疯狂的。默认铃声STILL播放，并且所选铃声同时播放。 HELP !!!

感谢!!!
