Status of VIA Envy24 audio controller

[Konstantin Dimitrov]

diffs to get old Katsurajima code running under FreeBSD 6.1 are here:
http://lists.freebsd.org/pipermail/freebsd-multimedia/2006-May/004223.html

Stefan, sent the initial diff ("mixer vol ..." is not working) for
"Audiophile 2496" yesterday to freebsd-multimedia@ :
http://lists.freebsd.org/pipermail/freebsd-multimedia/2006-June/004307.html

to fix "mixer vol ..." two additional changes are required (only 2 lines of
code):

1) as i said before, there is obvious bug, that affects all Envy24-based
cards, so no matter what card you have in ak452x.c "codec->type = dvc;"
should be changed to "codec->dvc = dvc;"
2) in envy24.c correct codec type should be set, for "Audiophile 2496"
change "ak452x_settype(ptr->info, AK452X_TYPE_4524);" to
"ak452x_settype(ptr->info, AK452X_TYPE_4528);"
