Proguard violates audio file in assets or raw

Question

I have an activity that plays an audio signal from MediaPlayer, which works great and is used to work even in the serial version. With the latest release, he now suddenly crashes with

I tried several different ways to download and play sound, including storing it in assets instead of the original res / raw, and they all work when I use an application that has not been profiled, but they all do not work with the release of a version that is predefined / zipaligned and signed.

My proguard file is quite large and contains a commonly suggested fix

-keepclassmembers class **.R$* {public static <fields>;}
-keep class **.R$*

Anyone have any ideas or something like that before?

Update: I also tried with mp3 files and had the same problems.
