Hi, I am porting sgtl5000 drivers to android 4.4.2, and there is still no sound, and when selecting from Setting->Sound->notification sound menu, some error shows in logcat,
log as below:

Some days ago, I made similar porting steps in android4.3, it works well, but it is not applicable to android4.4.
Where is the problem? Any suggestion is appreciated.
Thanks.
