[alsa-devel] modify the 0x21 pin config for ADATout (STAC927x hda codec) ?

[Eric]

Please somebody give me a simple way so as to have my 0x21 node Pin
config change
from my current (Default) 0x01452150: [Jack] SPDIF Out
to the aimed 0x01552150

If fact I bought these intel media motherboards ONLY for ADATout and
linux use.
Thanks in advance, Eric
