Class Driver AC3
Test - Win7
(System)

1256
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.

401
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.

Assertion FAE18121-9177-4FB2-A081-0D04C285EFF2 Bit
range 15:0 (Extended Capability ID)in the Enhanced Capability
Header register (offset 0h) in the Unrecognized Enhanced
Capability ID 13 table is Dh. It must be in the range [0x0 - 0xB]
as all other Capability IDs are reserved.

Erratum
HD Audio pin configuration document calls out setting Port
Connectivity to No Connection as the way to turn a pin off in a
particular system. UAA Test incorrectly tests such pins.

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.

Erratum
Preview filter - Jack Detect Override on digital pin widgets
Errata 1299 The HD Audio configuration default register
(7.3.3.31 in the HD Audio specification) includes a "Jack Detect
Override" flag that can be used to indicate that although a pin
widget would normally be capable of jack detection, there is
something about this particular system that causes this to be
impossible. This was intended to be used, for example, for
analog pin widgets that are connected to RCA jacks, which do
not allow for impedance detection. Some digital pin widgets are
using the Presence Detect pin sense response to indicate that a
digital handshake has occured - indeed, HDMI pins have entire
DCNs built around this concept, and it applies equally well to
S/PDIF pins. A digital converter that supports presence
detection should be able to do so in any system, so the "Jack
Detect Override" concept should not apply to digital pins.
