Same problem.
I figured out that this error only occurs when native method
   protected native int nativeStart( int decoder, BufferReader reader, Info info ) of class Decoder.
determines the wrong Samplerate. this happens rarely.

As a consequence, the AudioTrack constructor throws 
java.lang.IllegalArgumentException: Invalid audio buffer size.

Below a Logcat piece.
Determined samplerate is 11025, but shoud be 44100
