ALSA CVS update
D:2003/08/27 17:12:03
C:Documentation,VIA82xx driver
A:Takashi Iwai <tiwai@suse.de>
F:Documentation/ALSA-Configuration.txt:1.15->1.16
F:pci/via82xx.c:1.46->1.47
L:- use dxs_support=3 (48k fixed) as default, since there are so many problems
L: with dxs_support=0.
L:- added kernel boot parameter for dxs_support option.
