[Chris Peterson [:cpeterson]]

This is a strange crash. None of our code is in stack trace. Looking at Android's code, it looks like AudioManager.querySoundEffectsEnabled() might getting a mContext.getContentResolver() here:

https://github.com/android/platform_frameworks_base/blob/master/media/java/android/media/AudioManager.java#L1681

That is returning null from cr.acquireProvider() here:

https://github.com/android/platform_frameworks_base/blob/master/core/java/android/provider/Settings.java#L727

Then crashing here:

https://github.com/android/platform_frameworks_base/blob/master/core/java/android/provider/Settings.java#L737

This started to happen to me recently when using an automated script to install several system apks. I'm not sure this is the same problem for you guys, but here's how I fixed it: http://fr33kk0mpu73r.blogspot.com.es/2015/11/solving-nullpointerexception-at.html
