The PS5 Update 9.00 brings sound enhancements from the DualSense controller and Share Screen interactions to Sony's console.

The DualSense controller's sound enhancement is achieved through noise cancellation. Additionally, the update allows users to adjust the brightness of the console's power indicator with a new setting, as reported by Wccftech.

• Speaker enhancements. The controller's speakers can now play sound at a higher volume, allowing for clearer sound in games and voice chat.
• Improved noise cancellation. The sound quality from the microphone on the controllers has been improved with a new AI machine learning model. Background noise from button presses and game sounds are suppressed, enhancing the quality of voice chat. Install the new system software update and update the controller's software to enjoy improved clarity in voice chat when using the controller's microphone.

The system update should also improve system stability and performance.
