AC3 Test -

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
There is a known issue with StorPort.sys that may cause
hibernation to fail on a stressed system with memory
limitations. This can cause the Sleep and PnP test to fail with
the error "To Hibernate the system with SetSuspendState(...)
failed :
50". However, since this is a generic error that doesn't
reflect the true failure condition, it is necessary to root-cause
the failure on a case-by-case basis before adding drivers to
the erratum.

Auto Triage
The Signed Driver Check test may fail incorrectly if a file is
signed by multiple .cat files, where one is not signed for the
current OS. The test logs will show the wrong .cat file being
used to validate the file, while other files in the device
package are validated using the correct .cat file. If you
encounter this issue, please add the correct .cat file to a
'Supplemental Folder' in your .hckx submission package, and
use Manual Errata ID 1490 to cover the failure.

Errata
AllInOne desktop computers have the "Computer.AllInOne"
form factor. For this form factor, the test should recognize
the mouse and keyboard to be external to the main computer
machine. Without this filter it expects the mouse/keyboard to
be part of the computer which may not be the case. t.
