Erratum
SYSFUND-0062 Case 2 and 3 were added to enhance the
verification of the video playback test. These cases will be in
preview state until this errata expires. If cases 2 or 3 of the GFHD
test fail for any reason while this errata is active, then the
failures should be fitered out. Cases 0 and 1 do not apply to this
errata and remain a requirement

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
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
HDMI is required to support 44.1 kHz on Windows 7 The Windows
Vista HD Audio class driver does not support 44.1 kHz sample
rates. There is an errata to cover this violation of AUDIO-0023. It
was mistakenly applied to third-party drivers. As of Windows 7,
the Windows Vista HD Audio class driver supports 44.1 kHz
sample rates on hardware that advertises support for it. AUDIO-
0023 is applicable. This is a filter to allow vendors to ship with
systems that violated AUDIO-0023 but were incorrectly filtered
by the Vista filter. Hardware that does not support 44.1 needs to
be updated to support 44.1, and advertise that support in a way
that the Microsoft HD Audio class driver can pick up on. Third-
party drivers need to relay this support to the OS correctly.
