You want the intel if you want sound to come out the 1/8" jack on the back.

You want the nvidia if you want sound over HDMI from the video card.

Of course in my experience a simple way to get sound working when it
doesn't unfortunately is: killall pulseaudio

It shouldn't have to be that way, but well pulseaudio is pretty buggy
even if it is somewhat useful when it works.

Could also be a mixer setting problem.
