Preview filter - Jack Detect Override on digital pin widgets
Errata 1299 The HD Audio configuration default register
(7.3.3.31 in the HD Audio specification) includes a "Jack Detect
Override" flag that can be used to indicate that although a pin
widget would normally be capable of jack detection, there is
something about this particular system that causes this to be
impossible. This was intended to be used, for example, for
analog pin widgets that are connected to RCA jacks, which do
not allow for impedance detection. Some digital pin widgets are
using the Presence Detect pin sense response to indicate that a
digital handshake has occured - indeed, HDMI pins have entire
DCNs built around this concept, and it applies equally well to
S/PDIF pins. A digital converter that supports presence
detection should be able to do so in any system, so the "Jack
Detect Override" concept should not apply to digital pins.

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.
