Issue Description:
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
Issue Description:
HDMI audio devices are backed by video pipes; if a
graphics subsystem exposes three output ports, but
only has two video pipes, it is not possible to get all
three HDMI audio endpoints "active" simultaneously.

Issue Description:
Various Intel HDMI codecs do not correctly default to
the specified ASP channel mapping, which switches
channels 2 and 3.
The Intel HD Audio DCN 34-A2, HDMI/Multichannel,
defines a mapping between digital converter channels
and HDMI slots; see section 7.3.3.41 of the DCN. Much
of the verbiage is generalized in DCN 36-A to apply
equally to DisplayPort slots. The latest versions of all
DCNs are posted on Intel's HD Audio standards page:
http://www.intel.com/standards/hdaudio/
The default mapping from digital converter channels to
slots is expected to be 0 --> 0, 1 --> 1, 2 --> ***3***, 3 -
-> ***2***, 4 --> 4, 5 --> 5, 6 --> 6, and 7 --> 7.

Issue Description:
Various Intel HDMI HD Audio codecs do not correctly
implement Encoded Packet Type.
The Intel HD Audio DCN 35-A, HDMI/High Bit Rate, repurposes
bits 0 and 1 of the Pin Widget Control verb to be the Encoded
Packet Type (for example, "native" or "high bit rate.) See
section 7.3.3.13 of the DCN for further information:
http://www.intel.com/standards/hdaudio/
The codec is expected to perform validation on EPT values set
in this fashion. From the DCN:
If the value written to this control does not correspond to a
supported value as defined in the Pin Capabilities parameter,
