As outlined in previous discussion on this list, the outcome matrix for = togging these bits is somewhat arcane and seemingly lacking in cohesion, = but with only 3 bits, it's reasonable to expect that a motivated end = user will be able to eventually configure their own personal setup to = their needs.

Note that this is my first ever alsa patch and after review by wiser = craniums it may need fixin'. ;-)

plz dont hesitate to ask for such corrections!

tnx!

Well, I still think that these Smart 5.1 controls are too cryptic. ...and with this patch, you'll have even three such switches! IMO, it'd be (a little bit) better to have a single control to set up these things. For example, you can give an enum control that has 8 entries for SM51A,B,C setups.

Honestly, it's actually 4, because if the alt output thingy isnt turned = off, then surround routes off to nowhere...
