Location[5:0] indicates the physical location of the jack or device to which the pin
complex is connected. This allows software to indicate, for instance, that the device is
the "Front Panel Headphone Jack" as opposed to rear panel connections. The encodings
of the Default Device field are defined in
The Location field is divided into two pieces, the upper bits [5:4] and the lower bits
[3:0]. The upper bits [5:4] provide a gross location, such as "External" (on the primary
system chassis, accessible to the user), "Internal" (on the motherboard, not accessible
without opening the box), on a separate chassis (such as a mobile box), or other.
The lower bits [3:0] provide a geometric location, such as "Front," "Left," etc., or
provide special encodings to indicate locations such as mobile lid mounted
microphones. An "x" in
support. While all combinations are permitted, they are not all likely or expected.
Default Device[3:0] indicates the intended use of the jack or device. This can
indicate either the label on the jack or the device that is hardwired to the port, as with
integrated speakers and the like. The encodings of the Default Device field are defined
in Table 17-7.
Connection Type[3:0] indicates the type of physical connection, such as a 1/8-inch
stereo jack or an optical digital connector, etc. Software can use this information to
provide helpful user interface descriptions to the user or to modify reported codec
capabilities based on the capabilities of the physical transport external to the codec.
The encodings of the Connection Type field are defined in
Color[3:0] indicates the color of the physical jack for use by software. Encodings for
the Color field are defined in
Misc[3:0] is a bit field used to indicate other information about the jack. Currently,
only bit 0 is defined. If bit 0 is set, it indicates that the jack has no presence detect
capability, so even if a Pin Complex indicates that the codec hardware supports the
presence detect functionality on the jack, the external circuitry is not capable of
supporting the functionality. The bit definitions for the Misc field are in
Default Association and Sequence are used together by software to group Pin
Complexes (and therefore jacks) together into functional blocks to support
multichannel operation. Software may assume that all jacks with the same association
number are intended to be grouped together, for instance to provide six channel analog
output. The Default Association can also be used by software to prioritize resource
allocation in constrained situations. Lower Default Association values would be higher in
priority for resources such as processing nodes or Input and Output Converters. Note
that this is the default association only, and software can override this value if required,
in particular if the user provides additional information about the particular system
configuration. A value of 0000b is reserved and should not be used. Software may
interpret this value to indicate that the Pin Configuration data has not been properly
initialized. A value of 1111b is a special value indicating that the Association has the
lowest priority. Multiple different Pin Complexes may share this value, and each is
intended to be exposed as independent devices.
Sequence indicates the order of the jacks in the association group. The lowest
numbered jack in the association group should be assigned the lowest numbered
channels in the stream, etc. The numbers need not be sequential within the group, only
the order matters. Sequence numbers within a set of Default Associations must be
unique.
