Errata
The HD Audio class driver hdaudio.sys exposes AC-3
data ranges on S/PDIF Kernel Streaming pins
incorrectly.<br xmlns="http://www.w3.org/1999/xhtml"
/><br xmlns="http://www.w3.org/1999/xhtml" /> 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.<br
xmlns="http://www.w3.org/1999/xhtml" /><br
xmlns="http://www.w3.org/1999/xhtml" /> However,
the HD Audio class driver sometimes incorrectly
exposes a MaximumBitDepth of 24 or even 32.

Errata
The USB Esposed Port Controller Test is known to
fail without logs in certain configurations using the
xHCI Controller on this system. Please right-click
the failed task to review the Error information. If the
task failed with ExitCode c0000374, a manual
erratum might apply. Before using the manual
erratum, it is necessary to review the
PortMappingFinder.wtl log for the Port Mapping
Tool task. If the log contains any 'No companion
port for SuperSpeed port' errors, please contact the
xHCI Controller vendor for a firmware update and
do not attempt to use the manual erratum. If there
are no errors, but there is a 'Couldn't get connector
properties for hub' message, please use Manual
Errata 1435 in a Readme form. The erratum will
only be honored if this AutoTriage filter applies to
the Run Test task.

1407
Errata
The USB3 Termination test may fail to find the
USB 3.0 (Super Speed) device if the system's USB
ports are not numbered contiguously. While nearly
all systems have contingous USB port numbers, it is
not technically required. If this filter allows the
FindUsb3Device task to pass, then HCK Errata ID
1407 can be used in a Readme form to overturn the
remaining cancelled tasks.
