Preview filter - Jack Detect Override on digital pin widgets.
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.

Contingency
Certain Intel codecs swallow the first response after a
function group reset.
Issue Resolution: Intel will fix this in future revisions of their
codecs.

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.

Erratum
The HD Audio class driver hdaudio.sys exposes AC-3 data
ranges on S/PDIF Kernel Streaming pins incorrectly.
The compressed AC-3 transport is "stereo", "16-bit", and at
the same sample rate as the uncompressed format. As such,
AC-3 data ranges are expected to have MaximumChannels =
2, and MinimumBitDepth = MaximumBitDepth = 16.
However, the HD Audio class driver sometimes incorrectly
exposes a MaximumBitDepth of 24 or even 32.

Erratum
If a driver is found to be signed by Microsoft that is tested
with the chklogo test, the message, ERROR: No Logo Level
Attribute on file., is an invalid failure if followed by, This file
has a 0 level Logo and followed by,Cannot match the device
ID of the driver the device was test within an invidual
assertion.
Issue Resolution: Drivers that may have been logod but are
not associated with a valid hardware ID are attributed
incorrectly as unclassified drivers and incorrectly failed by
this test.
