Abstract: In an example there is provided circuitry for detecting a type of accessory connected to a first jack plug inserted into a first jack port. The circuitry is configured to determine whether an audio signal is present at the tip or the ring of the first jack plug. If there is an audio signal present at the tip or the ring of the first jack plug, then the circuitry is configured to determine that the type of accessory is a stereo line-in accessory connected to a 3-pole jack plug.
