So, this problem actually started a few hours ago in Windows 7 after a reboot. The only sound coming out of my headphones or speakers is a very quiet non stop beep, and no other audio plays.

I tried to install Windows 10, but that didn't fix the issue. Still the same thing is happening. I tried installing and uninstalling the Realtek driver software, but the only thing that did was make some really weird noises I can't even begin to describe. Anyone have any ideas on how to fix it?
