Audio callback function that works on hardware

[GreenDeveloper]

I'm working on a Wii port of Cave Story, and I and a few others have been struggling in getting audio to properly work on hardware (while it works perfectly on dolphin?).

The reason we need our own audio callback is that we need to use a custom sound buffer system because of the way Cave Story handles audio with literally everything having its own proprietary format.

Any help would be greatly appreciated!

It's difficult to provide help without seeing some code. It would also be good to know the nature of the problem - are we talking distorted sound or something more severe?
