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.

Erratum
Issue Description:
Windows 7 64-
bit
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.
