Open a terminal and enter the following command
 
$ cd /etc/modprobe.d
$ sudo gedit alsa-base.conf
 
and add these 4 lines to the bottom of the file (i.e right after options snd-pcsp index=-2)
 
options snd slots=snd-hda-intel
options snd-hda-intel model=hp-m4
alias snd-card-0 snd-hda-intel
options snd-hda-intel enable_msi=1
 
and restart the machine. Your sound should work now, good luck.
