Digital Playback Switch so it matches up with the corresponding Volume control, though I rather expect that this should in fact be controlled by the digital_mute() callback for the DAI rather than a control.

Anything called "Foo Mute Switch" is probably doing something wrong as a switch is already an on/off control.
