Good luck man.
When you listen to Spotify and pull down the notification bar , the sound accidently stop and start again , this also happens when you click the all apps icon in the home screen. Other music app has this problem too.
The battery life is much better with the newer audio source in deep sleep. Maybe it is related to the mic ( ivan said the android 4.4 keeps the mic on to wake the phone up just like Moto X did ) http://weibo.com/1697247850/AABoAhUUr

because there is something wrong with the kk_2.7 kernel branch.
