No Sound on HP EliteBook with Ubuntu Jaunty

Sound did not work on a HP EliteBook 2730p. It seemed the sound did not reach the speakers. I found the solution at for the EliteBook 2530p and some Linux distribution. It worked on the 2730p as well:

Open alsa-base.conf with any texteditor (here ‘gedit’) by typing
sudo gedit /etc/modprobe.d/alsa-base.conf
in the terminal.

Then add a line
options snd-hda-intel enable_msi=1 single_cmd=1 model=laptop
at the end of the file.

Save it and restart the computer.

PS: This is one-of-those-Newbee-with-Linux-problems which get solved by semi-competent replication of some geeky fiddling with foo.conf files in /etc or /boot or /bar folders … I have no Idea what alsa-base.conf is and why/how this works. I just found the fix with google at the site cited above and it works…
