Erratum
This happens because the PCI Compliance test assumes that if
the Data Link Layer Link Active Reporting Capable bit in the Link
Capabilities register for a given PCIe port is set then that
indicates that the Data Link Layer Link Active bit will also be set.
This is an incorrect assumption because the Data Link Link
Layer Link Active bit can be reset when there is no device
below the port. This assertion needs to be removed from the
PCIHCT. The current architecture of the PCIHCT prevents it from
knowing whether devices exist below a bridge/port.

UAA Test requires the Traffic Priority bit to be read/write -
however there are two specs that apply, and they conflict. One
says the bit must be read/write, the other says it must be read-
only. Contact has been made with the author of both specs
(Intel) but until this point is clarified we cannot fail submissions
containing this test failure.

The original HD Audio 1.0 specification contains a notion of
"presence detect", using electrical impedance which was
intended to apply only to analog pins. However, the language of
the specification was such that it could be read to apply to
digital pins as well - in particular, to S/PDIF pins.
A DCN was released to extend the notion of presence detect to
digital pins - in particular, to HDMI pins. This repurposed one of
the impedance bits, which were thought to be unused in digital
pins, to mean "ELD valid."
The correct way for a S/PDIF pin to respond to a Pin Sense verb
is to set the highest bit (Presence Detect) to 1 or 0
corresponding to whether a S/PDIF connection is active; set the
ELD Valid bit to 0 (since there is no such thing as ELD for
S/PDIF); and set the rest of the bits, which are reserved for
digital pins, to 0.
This errata filter is a preview filter to allow hardware
manufacturers time to update any hardware that used the
impedance bits on digital pins.

Erratum
Intel has published Document Change Notifications (DCNs) to
the High Definition Audio specification that specify new ways to
expose HDMI audio devices. These are available here:
http://www.intel.com/standards/hdaudio/
There are a number of HD Audio devices that were designed
prior to these DCNs being released. These expose HDMI audio
devices in accordance with the looser standard that was
published at the time.
UAA Test false-fails these devices under the stricter rules
established by the DCNs.

AUDIO-0062, effective June 1 2009, requires that any HD Audio
codec that advertises EPSS support comply with the Intel HD
Audio Low Power DCN.
