I have a question.  In alsamixer, the capture switch looks either like this:

                            ------

                          < Master >

or like this:


                            L    R
                            CAPTUR

                          < Master >

What exactly does this mean?  Which one is supposed to mean "muted"?
And how come even though this switch is a SOC_DOUBLE, I cannot control
the left and right channel independently with the < and > keys, and the
"M" key doesn't toggle it either.
