The Hummingbird A31 has headset and line in audio jacks and an onboard mic routed to the pins for the SoC's internal codec. The line out pins are routed to an onboard speaker amp, whose output is available on a pin header.

This pin group isn't used anywhere. Because of the strict thing in pinctrl, I'd say it's better to not set it, but then, the pin group is useless.
