So my linux system didn't have any audio output now while it worked days ago and I haven't installed any new package. I was working on this for at least two hours. Reinstall drive things like that and none worked. I thought to myself: do you really want a system without sound? I mean it's good for coding since you can focus knowing you cant watch video now since theres no sound. But do you really want it? No, I would rather reinstall it. So I closed my laptop, didnt shut it down, and searched for how to reinstall ubuntu in command line and reopened my laptop, and magically, the sound is back online...... I guess linux is more powerful than I have ever imagined.
