[NAME] I uninstalled and re-installed Bluetooth and audio drivers. It seems working fine now. But for the adaptive brightness problem I disabled it in the settings, still the problem is there.   
Hi, I have recently purchased Dell Inspiron 15 3515. My specs are AMD Ryzen 5 3500U 4C/8T processor, 8gb ddr4 ram, 512gb SSD with Windows 11 home. I am having Bluetooth audio lag issues and auto brightness issues. Even though I have disabled in the settings the brightness always changing. As for the Bluetooth audio there will 3-5 seconds delay between audio and video, sometimes audio will lag and sometimes video will lag while I am watching YouTube videos or other streaming services. I have uninstalled and reinstalled Bluetooth and audio drivers. Still the problem persists. I request you to solve my problem. Thanks in advance.
