This is a bug in the JNI interface due to a typo. The JNI code says

JNI_EXPORT void JNI_WRAPPER(EnableSpeakerStereoMode)(JNIEnv* env, jobject obj,
                                                     jlong j_ptr,
                                                     jboolean enable) {
  const VrAudioSystem* const vr_audio_system = NativePtrFromJPtr(j_ptr);
  DCHECK(vr_audio_system);
  vr_audio_system->vr_audio->EnableStereoSpeakerMode(enable);
}

but the Java code says private native void nativeEnableStereoSpeakerMode(long vrAudioSystemRef, boolean enable);

As a temporary workaround, you could create a JNI function called Java_com_google_vr_sdk_audio_GvrAudioEngine_nativeEnableStereoSpeakerMode which calls Java_com_google_vr_sdk_audio_GvrAudioEngine_nativeEnableSpeakerStereoMode.
