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.

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,
the control must either retain the previous value or take the
value of 00, which will select the default native audio packet
type.
