I vote for this too, and also to remove outdated comments about sr >

This is true only for multiface/digiface users. This step is not 
required for hdsp 96xx users.

Or with amixer (we should consider non-gui users). The amixer matrix 
mixer syntax explanations should be kept (and enhanced for hdsp 9632 
users : for the input parameter 0-15 = physical input, 16-31 = software

Or with amixer, again.

Nice one, thanks :)
