The asound.state entry

control.5 {
                iface MIXER
                name 'Capture Switch'
                value false
                comment {
                        access 'read write'
                        type BOOLEAN

This cannot be undone with the alsamixer command.

It can be activated with the command "amixer cset name='Capture Switch' on"
