Noise Suppression Quality is Poor While on Conference Calls Using a Headset

Affected Platforms:

• OptiPlex Micro Plus 7010
• OptiPlex Micro 7010
• OptiPlex Tower 7010
• Precision 3260

In VoIP conference calls (for example Microsoft Teams calls), end users have complained about hearing environmental noise or any unwanted sound, disturbing the VoIP experience and degrading the speech quality.

For USB and BT headsets: Waves audio enhancement conflicts with the noise cancellation feature from USB and BT headset. The latest audio driver removes Waves audio enhancement and resolves the problem.

• Waves APO (old) audio effect applied on external digital end-point device (USB headset), the audio enhancement also affects noise and background vocals.
• Waves APO (new) has disabled the audio enhancement on digital end-point audio device (no audio enhancement on those devices).

For 3.5mm headsets: Waves audio enhancement may conflict with the noise cancellation feature from the 3.5mm headset.

For USB and BT headsets: Update the audio driver to the latest version which is packaged Waves APO with removing digital end-point device (USB/BT) effect from the version and afterward. And all D13.5 audio drivers are applied to the change when released.

• D13 Luxor Wave APO version: v.12.2.0.846, which was released in March 2024.
• D13.5 Luxor MLK Wave APO version: v.13.2.0.15648, which was released in February 2024.
