Making Intel HDA STAC92XX sound card work in Kubuntu 9.04

For the purpose of documentation and a "mini" achivement, here is the workaround i did to make the sound work for HP Compaq 510 running Kubuntu 9.04:

1. open the terminal
2. gksudo gedit /etc/modprobe.d/alsa-base.conf
3. append the following lines at the end:

options snd-pcsp index=-2
alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
options snd-hda-intel enable_msi=1

4. System Setting > Multimedia > Audio Output > make Intel HDA STAC92XX as the first output device > Apply
5. restart kubuntu
