Hey! I was on the BIOS, and you know when you click something that isn't in the keys there, it does a sounds like... "EEEEENGH" or something? Like an error sound, I mean.
Well, it did that. It seemed weird to me, but didn't really look into it.
When I rebooted the computer, the X sign on the taskbar Volume icon was not there! I really don't know how it happened. I'm listening to music right now!
I'm going to reboot and tell you if it's still there, just in case; if it is, if I still have sound, I'll mark this post as solved
