Presence detect for Port E = 0 (nothing plugged in)
Port F Aux Audio input is routed to Port A, B, or D when that port is active.
If either Port A or Port B is in use (port presence detect = 1), Port D, internal speakers, will be
inactive (off)
The power supply for Port A and B will be active if either A or B is in use but if only one of the two
ports is in use, the other may be turned off to save power.
If neither Port A nor Port B is in use (port presence detect = 0), Port D, internal speakers, will be
active and ports A and B will be inactive.
Presence detect for Port E = 1 (something plugged in)
Port F Aux Audio input is routed to Ports A, B
Port D is disabled
If either Port A or Port B is in use (port presence detect = 1), that port will be enabled and output
the audio entering Port F.
The power supply for Port A and B will be active if either A or B is in use but if only one of the two
ports is in use, the other may be turned off to save power.
If neither Port A nor Port B is in use (port presence detect = 0), ports A and B will be inactive and
the audio on Port F will play through the dock using resources outside of the CODEC.
