Can someone help me pls? My hp chromebook speakers are not working.

So last week i went on my laptop, on youtube to listen to some music. but there wasnt any sound coming from the speakers. So i started to freak out. I turn my laptop off and on and it worked. It did the same thing for some day but every time i turned the laptop off and on it will work . But its been a week now and nothing is working. Ive tried everything from sound settings , off and on agains and even setting my battery out but nothing is working. Can someone help me pls. Tell me what to do or something. I really need it . Thank you .
