Oh heck! sorry about that.

i did cut n paste it into opera. i attempted to do the git-patch thing  
 from the alsa wiki and i couldnt generate a patch.

i will attempt to figure out how to use git correctly for my next patch  
for ac97 7.1 infrastructure.

when is later? doesnt need to be exact. rough estimate is fine.
