Lenovo 3000 N100 -- Sound With Kubuntu

Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02)

The sound driver has many options, but few seem to work with the ALSA sound system.

To get it to work at all edit the following file:

$ sudo nano /etc/modprobe.d/alsa-base

I have placed in this file all my hits and misses including comments about each. It is the last one that works the best.

# 3stack has more options, but no sound from speakers
#options snd-hda-intel model=3stack
# laptop-automute is the Lenovo default, but no sound from speakers
#options snd-hda-intel model=laptop-automute
# ultra has less options but everything works
options snd-hda-intel model=ultra

The total list of options for the AD1986A chip are below:

AD1986A Chip
