Good day all of you, guys.
Actually I am really concerned about the performance of my laptop. I am using the latest version of kali linux 2021.3 and laptop is lenovo ideapad L3. Problem is about I can't listen any music either see video in both: on my laptop as well as a on browser (I am using firefox). I have seen and tried provided answers about sound occurring in kali linux itself, but none of them helped me. And the same process happens in video errors. So please help me guys.

Thanks in advance.
