    Two of the Raspberry's GPIO pins on the P1 header are made available on the Wolfson card. They are normally used as the UART serial console, but that function is easy to disable. http://www.hobbytronics…

    Yes, most ultrasonic sensors I have seen use two GPIO pins. You can use the pins on the Wolfson card to connect it. -- Ragnar

    These basically discuss how to extend no. of gpio of pins but it is up to you to decide how to use them and configure the accessory attached to gpio pins(here PIface i think).

    Check this link for connecting a ultrasonic sensor and I dont think there is any option other than gpio pin extension.

    well but you could use external usb sound card in place of wolfson.And then use gpio pins for anything you want to do.
