Fujitsu Amilo Pi 1505 squeaking, crackling, scratchy sound

I installed Ubuntu 9.10 into my Fujitsu-Siemens Amilo Pi 1505. It has Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller. I had this horrible squeaking, crackling sound which would get worse when CD was accessed.

It would even play when I muted the PCM input.

The solution was to install gnome-alsamixer and mute the CD channel.

sudo apt-get install gnome-alsamixer
Applications -> Sound & Video -> GNOME Alsa mixed
Mute the CD channel

Here you go! No more crackling sound!

Hope this helps someone.
