S [4:0] (RO)
Sensed bits (when input sense cycle initiated). This field allows for the reporting of the type of input peripheral/device
plugged in the jack. Specified values should be interrogated with the SR [5:0] and OR [1:0] bits for accurate reporting.
ST [2:0]
Sense Value
0x10
Data not valid. Indicates that the reported value(s) is invalid
0x11
No connection. Indicates that there are no connected devices

Read/Write)
This field describes the location of the jack in the system. This field is updated by the BIOS. These bits are only reset by a
power-on reset because it is typically written by the system BIOS and is not reset by codec hard or soft resets as long as
power remains applied to the codec.
