What exactly is the problem with the alsa driver? Csound works
OK with it. Replacing it with OSS will require us to write a new
IO module for Csound. Without Csound, audio and music on
the XO will have to be completely re-written.
IMHO, developers wanting to use audio on the XO should ideally
use Csound and its Python API. That's why it's there.
As far as I am concerned, having developed audio apps for
Linux for several years, Alsa is much better and more reliable

If thats the case, then we need somebody to volunteer to write the AC97
driver for the CS5536. I don't think we would consider any sort of
change until the appropriate hardware controls are in place.
