Erratum
"High Definition Audio Device" devices need to
comply with the Intel High Definition Audio spec,
as well as revisions (known as Document Change
Notifications, or DCNs.) One such DCN - in
particular, DCN 34-A2 - clarified the behavior of
"pin sense" verbs as applied to digital pins (S/PDIF,
HDMI, and DisplayPort.) Prior to the DCN, the
language of the spec was unclear and mistakenly
implied that the "Impedance" bits could be used by
digital pins. The DCN clarified this to say that
Impedance bits are reserved for digital pins.

Erratum
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
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
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.
