The equalizer can be controlled with the control device that you have
defined with "type equal", in this, case "equal":
alsamixer -D equal
The volume can be controlled with the control device belonging to the
sound card that you specified with "control.card":
alsamixer -D hw:1 # this is the default anyway
For technical reasons, the softvol control can be attached only to
an actual hardware device, and the equalizer controls do not belong to
any hardware device, so you cannot have both at the same time. Your
only choice is to run two instances of alsamixer in parallel.
