Everytime I run a Youtube video, it takes over my sound. And, then later when I try to play my Spotify, it says my audio drivers are not working. Most times, I reboot the computer and it works OK, but it's just annoying have to restart and bring all my browser windows back up. I don't know why Youtube is taking over my sound like this (even after the tab is taken down). Just want it to stop. Suggestions on how to fix this would be welcome, please.
