does this one have both the capture and playback patches? if not, would
it be possible to combine the two, because i haven't had any success
patching the cvs alsa driver that already contains the capture (or is
that playback?) patch ...

i'm currently using the 008 patch, without too much drama ... except the
slightly frustrating capturing of playback channels along with ac97 ...
though this could be due to incorrect mixer settings ...
