Dear All

I'm using Dell Vostro 3350 now. After I upgrade Win 10 Pro, the Laptop Speaker doesn't work and can't give output any sound. But if I put my earphone, all of the sound include song work.

I use PC Doctor and scan the computer hardware but there is nothing found error on hardware and software. I also use windows update to scan all of the drivers, but it can't found any update drivers of this laptop. So what can I do next to fix the problem?

Thank you for member's attention
