Abstract: There is provided a USB audio accessory device, comprising: an audio transducer, configured to generate an audio transducer signal; interface circuitry, configured to receive analogue and digital representations of the audio transducer signal; and a USB-C connector for connecting to a USB host device, coupled to the interface circuitry. The interface circuitry is operable, in a first mode of operation, to output simultaneously the analogue representation of the audio transducer signal over a first pin of the USB-C connector, and the digital representation of the audio transducer signal over second and third pins of the USB-C connector.
