AC3 Test – Win
7 (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
The following PCI Compliance test failure is acceptable: Bit 15
(Bridge Configuration Retry Enable) in the Device Control
register (offset 8h) in the PCI Express Capability table must be
read-only and always return 0 as it is reserved for devices other
than PCI Express to PCI/PCI-X Bridges. Assertion 13A41D3E-
2576-41DC-A67C-525DA3637CEA This failure is acceptable
because this is a PCIe 1.1 feature and the WLP requires
compliance with only PCIe 1.0a.

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.
