Dell Optimizer Audio Panel Option Missing and Audio Jack Detection Issue after Windows 10 Installation

Affected Products:

• Dell Optimizer

Affected Platforms:

• Latitude 5320
• Latitude 5520

Affected Operating Systems:

• Windows 10 21H2

Affected Versions:

• BIOS v1.17.2 to 1.19.1

• When BIOS versions 1.17.2 to 1.19.1 are installed there appears to be an issue with detection of connected audio jack devices (headsets, headphones, speakers so on), which do not get detected at all, unless the audio device is connected on boot up (and then only until they are removed, not after replugging).
• When Dell Optimizer is installed, the Audio Panel and Option pane is missing,
  • No Dell Optimizer audio settings and adjustments are available, severely limiting the functionality of the Latitude 5320.
  • Dell Optimizer is required for full audio functionality, including microphone input using the audio jack.
    

Interplay of BIOS, Audio driver, and Windows installation is the cause of the issue.

The engineering department is provided on a fix to be released in BIOS version 1.20.0 and later. The updated BIOS is posted to the computer's support page.
