Run AC3 test on a system with the Microsoft HD Audio class
driver installed. Expected results: All AC3 kernel streaming
data ranges should advertise MinimumBitsPerSample = 16 and
MaximumBitsPerSample = 16. Actual results: HD Audio class
driver sometimes advertises MaximumBitsPerSample = 24.

Erratum
Errata 142 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.
