That's a very good and eminently reasonable idea. Having said that....
I am deeply hesitant to do anything automagic at this point for several reasons:
1. This is my first ever patch and i may have hosed something, so why compound my folly? :-)
2. The documentation from via on vt1617a Smart 5.1 is quite mistake ridden and getting something to work on my 1 sample of a via epia c-7 was an exercise in forensics.
3. Smart 5.1 is not utilized on all boards - recall that i started from a patch 2 14rc2 submitted by Daniel Jacobowitz that enabled surround to work on a shuttle board with traditional jacks.
4. Board vendors that use Smart 5.1 may be using it differently then how things are done on the board that i have - what if they only bidirectionaled 1 connector? which one?
Ideally, fixing up the alsa-lib conf file should come after some results from the field.
tnx!
