Hissing Sound in Headphones when connected to Laptop with Ubuntu Os

I used my laptop for a while with headphones, it worked fine. It’s a battery dead for an Hour. When I tried to watch a video, I’m getting a constant hissing sound . It stays even after closing the video file. I’ve gone through all git and forum pages, none of it helped. I think it’s better to move back to windows rather than this buggy Os with poor forums. NONE of Threads helped . Should I reinstall the Os again?
