Well, my problem is, I want my audio working, and i don't really care 
too much exactly where it takes me.  I saw comments in the hda code 
saying that it was going to be rewritten, so that's my current target.

I did try, momentarily, the oss4 drivers I found, but they don'[t 
compile under FreeBSD-current either, so the bus structure has 
undoubtedly changed.  This means (to me) that I am woefully ignorant of 
what I need, to be able to contribute.  At least, NOW I am, but it just 
means that I need to learn it.  OK, then, I suppose my target is first 
the -current list, then the developers I see are still slowly 
contributing, when I checked cvs logs.

Thanks for the pointers.  I'm finding, there are a LOT of folks on this 
list who follow poor courtesy, top posting, not trimming context, and 
cross-posting.  Doesn't anyone care?  My mailbox is getting full from 
all the cross-posting.

I'm not perfect myself on that, but at least, I do try.  More'n some 
folks do.
