Solution for audio on a f3sa laptop.
First install the latest version of Alsa 1.0.15 final.
After, you create a file in /etc/modutils called, for example, 'alsa' with this sequence of aliases and options:
alias char-major-116 snd
alias snd-card-0 snd-hda-intel
# module options should go here
options snd-hda-intel model=lenovo
# OSS/Free
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0
# card #1
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
The most important is the line:
options snd-hda-intel model=lenovo
For a secure success, add the line above in the file /etc/modprobe.d/alsa-base too
If it doesn't exixt, create!
After you must restart. Before you start to dancing, run 'alsamixer' and unmute all channel and set the volume.
