Put on my nuclear-grade asbestos suit and cvs rm the old, broken, sound
drivers (again). These drivers have not compiled for 5-6 months.
Now that the new sound code supports MIDI, the major reason we had for
reviving it is gone. It is a far better investment polishing the new
midi code than trying to keep this on life support. Come 5.0-REL, if
there are major shortcomings in the pcm sound driver then maybe we can
rethink this, but until then we should focus on pcm.
Remember, these have not been compilable since ~April-May this year.
