Erratum
Preview filter - Jack Detect Override on digital pin widgets Errata
1299 The HD Audio configuration default register (7.3.3.31 in the HD
Audio specification) includes a "Jack Detect Override" flag that can be
used to indicate that although a pin widget would normally be
capable of jack detection, there is something about this particular
system that causes this to be impossible. This was intended to be
used, for example, for analog pin widgets that are connected to RCA
jacks, which do not allow for impedance detection. Some digital pin
widgets are using the Presence Detect pin sense response to indicate
that a digital handshake has occured - indeed, HDMI pins have entire
DCNs built around this concept, and it applies equally well to S/PDIF
pins. A digital converter that supports presence detection should be
able to do so in any system, so the "Jack Detect Override" concept
should not apply to digital pins.

HD Audio pin configuration document calls out setting Port
Connectivity to No Connection as the way to turn a pin off in a
particular system. UAA Test incorrectly tests such pins.

Erratum
Preview Filter - Encoded Packet Type: The Intel HD Audio DCN 35-A,
HDMI/High Bit Rate, repurposes bits 0 and 1 of the Pin Widget
Control verb to be the Encoded Packet Type (for example, "native" or
"high bit rate.) See section 7.3.3.13 of the DCN for further
information: The codec is expected to perform validation on EPT
values set in this fashion. From the DCN: If the value written to this
control does not correspond to a supported value as defined in the
Pin Capabilities parameter, the control must either retain the
previous value or take the value of 00, which will select the default
native audio packet type.

Contingency
Various Intel HDMI codecs do not correctly default to the specified
ASP channel mapping, which switches channels 2 and 3.
The Intel HD Audio DCN 34-A2, HDMI/Multichannel, defines a mapping
between digital converter channels and HDMI slots; see section
7.3.3.41 of the DCN. Much of the verbiage is generalized in DCN 36-A
to apply equally to DisplayPort slots. The latest versions of all DCNs
are posted on Intel's HD Audio standards page:
http://www.intel.com/standards/hdaudio/
The default mapping from digital converter channels to slots is
expected to be 0 --> 0, 1 --> 1, 2 --> ***3***, 3 --> ***2***, 4 --> 4, 5
--> 5, 6 --> 6, and 7 --> 7.
