I just recently updated my Surface Pro 3, but I'm not sure if this is the cause of the problem. I'm not getting any sound playing out of the built-in speakers on the computer. Increasing the volume doesn't help, there's still no sound. I tried restarting my Surface Pro 3, but still not getting any sound. Headphones work just fine on the computer. I also tried USB speakers (the kind that doesn't use the earphone jack), and that also works just fine. It's just the speakers built into the Surface Pro 3 that's not getting any audio. Can anybody please help me?
