PandaBoard has a bit different set of audio features compared to SDP4430: - No DMIC - Earphone pins are not connected - Vibra is not connected
On PandaBoard 4430: - FM receiver is connected to AFML/R input - FM transmitter is connected to AUXL/R output - Input jack is connected as to HSMIC
On PandaBoard ES: - FM receiver/transmitter is not connected - Input jack is connected to AFML/R
