Errata 1444 PREVIEW FILTER - 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 preview Errata 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.

HDMI audio codecs sometimes expose more HDMI audio pins
(audio outputs) than can be plugged in at any given time, due to
resource costraints in the video hardware.
Test will need to be rejiggered to allow testing each in turn.
