Erratum
This happens because the PCI Compliance test assumes that if the
Data Link Layer Link Active Reporting Capable bit in the Link
Capabilities register for a given PCIe port is set then that indicates
that the Data Link Layer Link Active bit will also be set. This is an
incorrect assumption because the Data Link Link Layer Link Active bit
can be reset when there is no device below the port. This assertion
needs to be removed from the PCIHCT. The current architecture of
the PCIHCT prevents it from knowing whether devices exist below a
bridge/port.

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. The Fidelity Test tests headphones
at 300 Ohm load, though. Without knowledge of the output
impedance at the jack, the test cannot extrapolate what the output
level at 32 Ohms would have been from the output level at 300
Ohms. The test assumes that the output level at 32 Ohms will be
*less* than the output level at 300 Ohms, though. So any
measurement >= 120 mVrms at 300 Ohms "could be" a passing
result, depending on the output impedance.

Erratum
Fidelity Test includes a "System Activity Test" that verifies audio
fidelity is not compromised during system activity. It uses an activity
generator called rws.exe (Real World Stress) which has a bug that
causes it to hit an access violation. When this happens it exits with
return code 0xC00000005, or -1073741819.

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.

Run "Data Intersection Test\Capture Streaming\Check Supported
Formats" out of WaveTest on a system containing audio devices that
are "disabled" via the Sound Control panel. Expected results: should
succeed. Actual results: fail with "Failed to find any endpoints for the
current pin" and "Failed to decide if current data intersection test
should be skipped"
