There are a couple things you might try - See Audwin101's post in this thread here. [URL] Also, Dex-001's post in this thread below might help you as well. That one helped me figure out my issue with my XPS 15 9570.   [URL]#M95114  
Starting about 2-3 days ago, I have had strange issues when playing videos from the internet. They sometimes take quite long to load and start, about 10-20 seconds, although the internet connection is good. The problem seems to happen more often when I plug in my headphones. The same thing happens when I plug in the headphones while a video is playing, it suddenly hangs and takes a long time to load and continue. Videos from the local hard drive play without problems when I plug in and out the headphones. There is another problem with the sound control noticing the headphones: when I plug and unplug it twice, it does not get noticed any more. I have tried to uninstall recently installed updates and also looked for possible new updates but nothing helped. Anyone else having similar problems? Windows version: Windows 10 Home, 21H1
