Ubuntu 9.04 AD1986A snd-hda-intel driver

I had reinstalled my desktop with the latest Ubuntu 9.04. As usual, the on-board sound of my ASUS P5GL-MX registered as AD1986A does not work correctly with the snd-hda-intel driver. The line-in jack picks up no sound. The reason, after much searching a few years ago, had to do with the wrong number of audio I/O jacks being recognised in the default kernel module settings for the driver. To solve it, add the line:

options snd-hda-intel position_fix=1 model=3stack

To the end of the file:

/etc/modprobe.d/alsa-base.conf

Reboot and now line-in sound works like it should.
