WM8753 Speaker Playback ZC Switch

[Ed Kapitein]

Hi All,

I am happily hacking on my FR and was toying with the wolfson.
I happen to notice that in order to get any sound from the earpiece i
had to switch on the Speaker Playback ZC Switch.
That switch is mentioned in the statefile, but i can't find it in any of
the diagrams on [1] [2]

Is there someone with an updated version of the diagrams, that includes
the two switches below?

        control.9 {
                comment.access 'read write'
                comment.type BOOLEAN
                comment.count 2
                iface MIXER
                name 'Headphone Playback ZC Switch'
                value.0 false
                value.1 false
        }
        control.10 {
                comment.access 'read write'
                comment.type BOOLEAN
                comment.count 2
                iface MIXER
                name 'Speaker Playback ZC Switch'
                value.0 true
                value.1 true
        }

Kind regards,
Ed
