No sound ?

My sound worked the entirety of me being on my PC but when I decided to go to league I tried to reset sound and fix it and all this stuff and afk to try and fix it , I did that when my lane was pushed in btw and stayed under turret , just think of it as playing defensive but for 1) hopefully this doesn't result in me getting in trouble and 2) hopefully this will be fixed ? idk if anyone else was affected by this but yeah kind of annoying to say the least , I fiddled with sound settings in and out game and even unplugged my speakers and it continued to stay mute , please fix also if ur a keyboard warrior don't respond thanks . I don't like the toxic kids on here I don't mean that in a rude way just being toxic doesn't fix the problem ..
