Lenovo 3000 N100 -- Sound With Kubuntu

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 sound card are below:

AD1986A
6stack 6-jack, separate surrounds (default)
3stack 3-stack, shared surrounds
laptop 2-channel only (FSC V2060, Samsung M50)
laptop-eapd 2-channel with EAPD (Samsung R65, ASUS A6J)
laptop-automute 2-channel with EAPD and HP-automute (Lenovo N100)
ultra 2-channel with EAPD (Samsung Ultra tablet PC)
