Subject: [PATCH] [UBUNTU:sound/pci/] Make DXS_SRC the default for VIA8235/8237/8251 chips

UpstreamStatus: Added in upstream hg changeset 4204:5cf914368b6efd432e5e8b7f9c1e3e253b27520e ,
                http://sourceforge.net/mailarchive/forum.php?thread_id=10258438&forum_id=33141

Takashi Iwai committed this change to make DXS_SRC the default mode for
newer VIA chips. For the older VIA8233/A/C chips, the old default
DXS_48K is used.
