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)
