All, The default headset registry setting is currently misplaced in the WT4090. It should be in: [HKEY_LOCAL_MACHINE\Drivers\BuiltIn\WaveDev\Default\Headset] but instead it is in: [HKEY_LOCAL_MACHINE\Drivers\BuiltIn\WaveDev\VOIP\Default\Headset].   A cab file has been generated as a hotfix and is posted at support central at the following location https://support.symbol.com/support/search.do?cmd=displayKC&docType=kc&ex... 0 193080651

or:

1. Go to https://support.symbol.com/

2. Click on Product Fixes (right hand side)

3. Click on WT4000 Fixes

4. Click on WT40xx - Registry Patch of Incorrect Audio Tuning - SPR 19296

This fix has deafult registry setting for headsets that should be used for Voice Directed Picking and thus it is imperative that it should be loaded onto WT4090 (all configs including the Voice Only Wearable)
