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
There is a test bug which causes the
measurement of system noise during Render
Power Transition Test to be about 3 dB worse
than it should be. This filter forgives errors up to 6
dB.

Erratum
Issue Description:
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.
Resolution Description:
This errata covers headphone output level failures
where the output level >= 120 mVrms (-45.41
dBV.) 120 mV is -18.42 dBV. Any headphone
output level at 32 Ohms that is less than -18.42
dBV is a legitimate failure, even if it is targeted at
EU compliance. Any headphone output level
greater than 1 Vrms (0.707 Vrms for mobile
systems) is a legitimate pass, regardless of EU
compliance.
