The emulator is now sounding more like a real audio player .

These are temporary fixes.

Silences clippy.

It's stil glitchy and noisy, need to check the problems.

Still requires work to be able to be able to emulate APU together with the CPU instead of inverting the control.

There's still a lot of work needed.

This a very work in progress situation that requires stability.
The most important part is the fact that it's possible for an external entity (SDL) to call an audio tick and get a volume.
