New laptop, but no sound.

I just got my new laptop today and after setting it up I realized there was no sound, from both the internal speakers and plugging in earbuds. I looked up guides on the internet, but everything i tried didn't work.

List of things I tried:

-Reinstalling drivers

-Manually installing drivers

-Muting and unmuting the laptop

-Checking for driver updates (it said that they were up to date)

I did something that made the sound come back for a little bit, but I forgot how I did it, so I guess that rules out speaker malfunction. I do have a pair of headphones that plug in through a USB port and sound comes out of that fine, but I would still like to use my earbuds and the laptop speakers.

Thanks for any help!
