4. Advance Jack Sense May Not Recognize Devices Connected to a
Front Panel Audio Port
PROBLEM: The advanced jack sense with Auto Topology Switching, that is used by the audio codec to
recognize what device is connected to an audio port, may fail to report devices connected to a front-panel
port.
IMPLICATION: Devices connected through a front panel audio port will be detected and function correctly, but
the advance jack sense wizard will only report the device at start up.
WORKAROUND: None.
STATUS: This erratum will not be fixed.
5. Advance Jack Sense on Boards with 6-Channel Audio Will Report
“Microphone” for Any Device Connected to the Back Panel
Microphone Port (Pink)
PROBLEM: For boards with 6-channel audio, the advanced jack sense with Auto Topology Switching, that is
used by the audio codec to recognize what device is connected to an audio port, will report “Microphone” for
any device connected to the back panel pink microphone port.
IMPLICATION: The advanced jack sense wizard will report any device connected through the back panel
microphone port to be a “Microphone” and the wizard will prompt the user to verify this detection assumption.
WORKAROUND: None.
STATUS: This erratum will not be fixed.
6. Advance Jack Sense Will Not Detect Devices Connected to the
Center/LFE and Surround Ports
PROBLEM: Polling devices connected to the Center/LFE and Surround port would cause popping noise once
speakers are connected. Due to this anomaly, the advance jack sense wizard will not poll and report devices
connected to the Center/LFE and Surround ports although these devices will work correctly.
IMPLICATION: Devices connected to the Center/LFE or Surround port will be detected and function correctly,
but the advance jack sense wizard will not poll and report the device.
WORKAROUND: None.
STATUS: This erratum will not be fixed.
7. Advance Jack Sense May Report Amplified Speakers as an Array
Microphone When Connected to The Microphone Port (Pink)
PROBLEM: The presence of voltage bias on the microphone jack during the detection phase is required for
accurate detection, but amplified speakers and array microphones have very similar impedance values.
IMPLICATION: Amplified speakers will be detected and function correctly, but the advance jack sense
wizard may report the device as an array microphone.
