What I was getting at was that although I can't do:

$ amixer sset Capture 192 

if Capture is defined by the softvol plugin, and I haven't opened the 
device prior to running amixer, however

$ alsactl restore 0:

works, assuming that I've saved the settings previously, even before the 
device is opened. I can understand that this is very useful and desired, 
but given that the underlying control does not yet exist, it puzzles me 
that it actually works.
