When your BIOS does not setup pin default for all pin comples

The only way you get your alc880 work is to edit
/etc/modprobe.d/alsa-base.conf and add the following line if your
motherboard have six audio jacks and digital out at rear panel

options snd-hda-intel model=6stack-digout

or

options snd-hda-intel model=6stack-automute

If your computer chassis have a hda front audio panel which support jack
detection
