That stuff is unmaintainable and is unmaintained. And is a big steaming
pile of butt ugly code.

The ALSA, OSS. PA, ESD, JACK, etc. etc. drivers are part of the "windows
95 audio model" problem. Just adding an OpenAL driver to the mix won't
make the problem go away. It would rather add to the smell of the pile.

So one can waste time on trying to patch and cleanup the Win95 driver
model and still be on a dead end road.

Or fix it for good.
