Well, wouldn't the most logical thing be to enable "Smart 5.1" if we 
have a surround profile, and disable it if we have line or mic input?

That is, assuming that the stuff actually works - I'm still trying to 
understand the "Independent HP"/"Jack detect" stuff (another strange 
thing in the VIA codec driver), what's causing headphones on Asus 
K50IJ/K60I not to work, and why toggling the switch crashes alsamixer... 
:-( I was hoping to be able to fix some of that by the time of merge 
window for 2.6.38, but I'm not sure I have the time/priority to do so.
