crackling audio and brightness slider not working

[LB777]

Opened youtube today and sound is crackling, video out of sync, worked fine last night. No updates done, nothing changed on computer. Everything up to date, did reinstall of audios, troubleshooter says everythings fine. If no updates what could have happened overnight? Is it laptop or windows 11? Static so bad can barely hear.

I was having a problem with brightness slider,  didn't work. Have to manually to darken.  Don't think I did anything to change computer, couldn't find fix. Seen both problems on internet- is something going on? Bad updates or viruses?
