SIE today pushed the beta version of the PS5 system upgrade to some players (mainly players in Japan and the United States, players who can upgrade this system will receive relevant contact emails), and the new features added in this version mainly include:
DualSense Sound Improvements: Improved sound functionality by updating the DualSense and DualSense Edge wireless controller software. Improvements to the controller speaker allow for louder volume** sounds, and the sound of game effects and voice chat will also be clearer. Improved noise cancellation performance of the handle microphone. With the introduction of new AI learning, the sound of button operation and the noise of the surrounding environment will be reduced, and the input sound quality of the controller microphone will be improved. This update may make the controller louder, and you can adjust the volume through the Control Center. 
Share screen interactions: In full-screen mode**, players who share their screen can use their mouse and emoji to post their thoughts on the game screen. Players can move the mouse pointer on the game screen to draw lines, or use "markers" to temporarily indicate the screen position to guide the streamer to play. * players can express their thoughts through emojis and encourage streamers with visual expressions. Note: This feature is on by default, but players who share their screen can turn off [Audience Interaction] through the Share Screen setting. During the beta period, both streamers and a** will need to be eligible for the beta version to experience this feature. 
PS5 console power light brightness adjustment: You can adjust the brightness of the PS5 console power lamp.
