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.
