Ariff seems to be > working on something else: http://people.freebsd.org/~ariff/ I was operating under the assumption that those comments from hdac.c, about the snd_hda driver badly needing a complete rewrite because it was insufficiently, well, bussed? Yeah, bussed meant that code rework was ongoing. If you even know what that comment about the busses being less than they might be means, IF you could point me at any driver that you personally think shows a more *ideal* setup, it would at least make me aware of what's really wanted. You don't need to describe it yourself, I know that'd be a major bore to do that for me, and I could probably learn as well by just reading code that illustrates what things *should* be. > > So feel free to dig into the sound code (we wouldn't mind to get some > patches which document the sound system a little bit more ;-) ).
