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
EU restrictions place a cap on the output level of headphone
jacks at 32 Ohm load: headphones are not allowed to have an
electrical output of more than 150 mV at that load.
We test headphone jacks at 300 Ohm load; the relationship
between the output at 32 Ohms and the output at 320 Ohms
depends on the output impedance of the headphone jack.
In particular, if a headphone jack meets the EU requirement of X
<= 150 mV at 32 Ohms, depending on the output impedance, it
could output a huge amount of power at 300 Ohms, or very
slightly over X mV. Since we require X >= 120 mV at 32 Ohms,
absent knowledge of the output impedance we can only require
X >= 120 mV at 300 Ohms.
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.
This errata covers output level failures for headphone jacks
between -18.42 dBV and 1 Vrms/0 dBV (0.707 Vrms/-6.93 dBV
for mobile systems)) in accordance with note 6 of the WLP
fidelity requirements.
