Erratum
Run AC3 test on a system with the Microsoft HD Audio class
driver installed. Expected results: All AC3 kernel streaming data
ranges should advertise MinimumBitsPerSample = 16 and
MaximumBitsPerSample = 16. Actual results: HD Audio class
driver sometimes advertises MaximumBitsPerSample = 24.

Erratum
Errata 142 HDMI is required to support 44.1 kHz on Windows 7
The Windows Vista HD Audio class driver does not support 44.1
kHz sample rates. There is an errata to cover this violation of
AUDIO-0023. It was mistakenly applied to third-party drivers. As
of Windows 7, the Windows Vista HD Audio class driver
supports 44.1 kHz sample rates on hardware that advertises
support for it. AUDIO-0023 is applicable. This is a filter to allow
vendors to ship with systems that violated AUDIO-0023 but
were incorrectly filtered by the Vista filter. Hardware that does
not support 44.1 needs to be updated to support 44.1, and
advertise that support in a way that the Microsoft HD Audio
class driver can pick up on. Third-party drivers need to relay this
support to the OS correctly.

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.
