AC3 Test –

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 plays a quiet (-60 dB FS) test tone during System
Activity test which is filtered out of the noise level
measurement.
However, Fidelity is quite prone to glitches during system
activity... the glitches leak into the measured noise, causing
false failures.

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.
