Earpiece Function
Capabilities: enum Items: 'Off' 'On' Item0: 'Off'
On Fremantle there's no "Earpiece Function", but there's "Earphone Function", which doesn't exist on Nemo. These might refer to the same thing. There's also "Earphone" on Fremantle, which is apparently used for earpiece volume control. There's no obvious counterpart on Nemo, but "Mono DAC" seems to work pretty well as the earpiece volume control.
