Wii U Home button crash


I need some help fixing an issue with Unity fmod studio running on the Wii U. We recently submitted our game Hive Jump to Nintendo’s lot check system. We failed with one of the reasons being that the game crashes when the user hits the home button on the Wii U game pad. I found that this issue only happens after the RuntimeManager gets initialized. The only messages from fmod I see on the Wii U that I don’t see on the PC are the following:

OSDriver_Register failed for SNDD driver
OSDriver_Register failed for SNDD_RAMP driver

I’m not sure if these warnings are relevant or not, but it’s my only lead.
Any help I can get would be greatly appreacieated.
