My sound card is "Game Theater XP 5.1".
This command:
sudo alsa force-reload
Gives:
Unloading ALSA sound driver modules: snd-cs46xx snd-ac97-codec snd-pcm snd-seq-midi snd-seq-midi-event snd-rawmidi snd-seq snd-seq-device snd-timer.
Loading ALSA sound driver modules: snd-cs46xx snd-ac97-codec snd-pcm snd-seq-midi snd-seq-midi-event snd-rawmidi snd-seq snd-seq-device snd-timer.
So it seems ok to me.
I tried to uninstall and reinstall with these commands:
sudo apt-get remove --purge alsa-base pulseaudio
and
sudo apt-get install alsa-base pulseaudio
This is the output of the second command (in english, thanks for your comment):
