AC3 Test –
Win7 (System)
06/01/2010 1572
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
Fidelity Test includes a "System Activity Test" that verifies
audio fidelity is not compromised during system activity.
It uses an activity generator called rws.exe (Real World Stress)
which has a bug that causes it to hit an access violation. When
this happens it exits with return code 0xC00000005, or -
1073741819.

ISSUE: PCI Compliance - Bit range 11:10 (ASPM Support)in the

table must be read-only. RESOLUTION: The following PCI
Compliance failure assertion is allowed 4D19D0E6-51CC-49CF-

Erratum
This happens because the PCI Compliance test assumes that if
the Data Link Layer Link Active Reporting Capable bit in the Link
Capabilities register for a given PCIe port is set then that
indicates that the Data Link Layer Link Active bit will also be set.
This is an incorrect assumption because the Data Link Link
Layer Link Active bit can be reset when there is no device
below the port. This assertion needs to be removed from the
PCIHCT. The current architecture of the PCIHCT prevents it from
knowing whether devices exist below a bridge/port.

UAA Test -
Win7 (System)
12/01/2009 1394
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.
