[CM] snd-8 capture question

[Bill Schottstaedt]

I think others have mentioned that that device doesn't
work in Snd -- I don't have one, so it's hard to fix.

I think the error message is trying to say that
there aren't any active output channels (which is
independent of the hardware -- did you activate at
least one output channel?).  You also need to activate
at least one input.  As the default, the recorder just
shows the signals it can find.
