I did a dual-boot of 16.04 Ubuntu and windows 10. for a couple of days my system worked fine but now I have no sound in both ubuntu and windows.
After reading the forums, I tried to install pulse-audio but I don't see any output other than HDMI.
Can anyone help on how to get the drivers?

David, I am not sure why but in my alsamixer or anything it says that I have no devices connected to my laptop except for the HDMI, which I do not want to adjust, I just want to be able to hear sounds from my laptop.
I appreciate your help.
