Erratum
UAA Test wrongly tests pin widgets that have their
Configuration Default register's Port Connectivity field set to No
Connection.
The Microsoft HD Audio Pin Configuration guidelines specifically
call out "set Port Connectivity to No Connection" as the official
way to turn a pin off. UAA Test should ignore any such pins, as
will the Microsoft HD Audio class driver.

Preview Filter - Keepalive on low power digital outputs
AUDIO-0062, effective June 1 2009, requires that any HD Audio
codec that advertises EPSS support comply with the Intel HD
Audio Low Power DCN.
The Low Power DCN, in turn, says that support for EPSS is
mandatory after July 1st 2011.

Note the sentence "KeepAlive Enable is mandatory after July
1st 2011, if EPSS is reported set to 1."

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
Fidelity plays a quiet (-60 dB FS) test tone during System
Activity test which is filtered out of the noise level
measurement.
However, Fidelity is quite prone to glitches during system
activity... the glitches leak into the measured noise, causing
false failures.
