  00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 01)
me presente une carte bien pauvre...

  # cat /proc/asound/card0/codec#* | grep Codec
  Codec: Analog Devices AD1984

Donc, je regarde la doc et je vois:
  AD1984
  ======
    basic         default configuration
    thinkpad      Lenovo Thinkpad T61/X61
    dell_desktop  Dell T3400

Donc, dans **''/etc/modprobe.d/alsa-base.conf''** , j'ajoute:
  options snd-hda-intel model=dell_desktop

Reboot ?  

====== Alsa ======
Configurer le son avec Alsa:
  # alsamixer
Sauvegarder la config
  # alsactl store

====== /dev/dsp et /dev/mixer ======
Il n'existe pas !\\
Si j'ai bien compris (?):
  - **''/dev/dsp''** et **''/dev/mixer''** sont gerer par OSS et non pas par Alsa.
  - **''udev''** devrait installer ces devices ! bugs ?

J'ai resolu le probleme en faisant:
  # modprobe snd-pcm-oss

Que j'ai, bien sur, ajouté dans **''/etc/modules''** (pour le prochain BOOT)
  ...
  snd-pcm-oss
  ...

Voila, je peux regler le son de ma tv ;-)

Regarder dans la documentation des sources, là:

A propos des "model", on y voit:

          6stack-dig    ditto with SPDIF

          laptop-dig    ditto with SPDIF
          auto          auto-confgi reading BIOS (default)

A essayer, pour ma sortie son TV ?:
  # modprobe saa7134-alsa

==== Soluce ====
Donc, dans **''/etc/modprobe.d/alsa-base''** , ajouter:
  options snd-hda-intel model=3stack-dig index=0

Et voila.
J'avais déjà le son, mais en plus avec la tv ;-)
