I found two ways around this for mine which as I say is almost identical to mine, since that didn't work,
Create a new document in you home directory,
copy and paste
sudo apt-get install module-assistant
sudo m-a update
sudo m-a prepare
sudo m-a a-i alsa
save it as whatever you like
Rightclick the document, select the permission's tab, tick the box which says Execute: Allow executing file as a program, then close
2xClick the doc and click run in terminal
It will start compiling, when asked to continue press Y enter.
It can seem as if it is stuck but it justs takes a little time.
Once it's done reboot and voila, sound.
If not, f**k knows lol
