So, I have maded the upgrade to ubuntu v.13.04, but, when I have maded this, my HDMI sound otuput sttoped to work... and, the HDMI sound device not appers any more on sound preferences :(

I don't have your hardware to verify (I can tell you it works fine on the previous hardware generation) this but I know my NVidia HDMI audio is broken on 13.04, the same fix may work for you this issues should be fixed in the next kernel update, in the meantime the mainline kernel (either 3.9rc8 or 3.8.8) should fix it Manual way:
http://kernel.ubuntu.com/~kernel-ppa/mainline/
You will want the all.deb and either every amd64.deb or i386.deb depending on weather you are using 32 or 64bit
Easy way:
How do I add the mainline kernel PPA?

If neither the 3.9rc8 or 3.8.8 kernels fix it for you, please mark this as not helpful

The 3.9.0 kernel should be out in a few days

Updating the kernel solved the problem for me, thanks! I used the 'easy way' to update my kernel and it worked like a charm. –  Achim A Apr 28 '13 at 13:43

I was facing the same problem. The following link helped me resolve it: http://ubuntuforums.org/showthread.php?t=2139459&page=3&p=12621337#post12621337

In short:

Go to the ALSA Launchpad and download the package: oem-audio-hda-daily-dkms* for your distribution. Then install it and reboot.

Great, that worked for me too. Thanks. –  reyquito Apr 30 '13 at 18:30
    
Inslling the package oem-audio-hda-daily-dkms_0.201305091410~raring1_all.deb from that PPA and doing a reboot fixed it for me too. –  Jorge Suárez de Lis May 9 '13 at 15:47
