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
The European Union requires the headphone output level to be
<= 150 mVrms for headphone jacks. There's a note in WLP
requirement AUDIO-0006 that states, in the presence of
regional regulations, the output level requirement for
headphones is dropped from >= 1000 mVrms to >= 120 mVrms.
This provides freedom for manufacturers to meet both the EU
<= 150 mVrms @ 32 Ohms and the WLP >= 120 mVrms @ 32
Ohms requirements.

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.
