Erratum
Error: attempted to set unsupported EPT 0b10 (Reserved);
previous value was 0b01 (Reserved); response was 0b10
(Reserved) For unsupported EPTs, the pin must either retain the
previous value or take the value of 0b00 (Native). See HD Audio
specification section 7.3.3.13.

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.
