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 ?

Configurer le son avec Alsa:

# alsamixer

Sauvegarder la config

# alsactl store

Il n'existe pas !
Si j'ai bien compris (?):

1. /dev/dsp et /dev/mixer sont gerer par OSS et non pas par Alsa.
2. 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

Carte mère: ASUSTeK P5B-Plus (Intel P965 Express)

Pas de son ?

Regarder dans la documentation des sources, là:

A propos des “model”, on y voit:

      AD1988
        6stack        6-jack
        6stack-dig    ditto with SPDIF
        3stack        3-jack
        3stack-dig    ditto with SPDIF
        laptop        3-jack with hp-jack automute
        laptop-dig    ditto with SPDIF
        auto          auto-confgi reading BIOS (default)

A essayer, pour ma sortie son TV ?:

# modprobe saa7134-alsa

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
