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
