12/01/2012 401 Erratum
Issue Description:
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.

Erratum
Issue Description:
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 f
ail submissions
containing this test failure.

Issue Description:
Specific codecs do not correctly support Input Enable and Output
Enable pin widget
controls. This results in an attempt to shut off the pin, and it
doesn't shut off. The Microsoft audio class driver has other ways
of making
sure the pins don't make sound, which
happen to work for these specific codecs.

driver installed. Expected results: All AC3 kernel streaming data
ranges should advertise MinimumBitsPerSample = 16 and

Audio class driver sometimes advertises
MaximumBitsPerSample = 24.
