Votre ligne est inopérante car deux des variables au moins ne sont pas bonnes, il faut utiliser /dev/dsp0 avec un audiorate=44150.

Bonne chance dans votre divertissement vidéo.

J'ai moi-même un soucis avec le son. J'ai acheter ce boîtier d'acquisition après avoir lu votre tutorial, en pensant trouver un matériel parfaitement compatible Linux, mais ce n'est visiblement plus le cas.

J'ai suivi la démarche, mais en téléchargeant les sources avec mercurial je me suis rendu compte qu'il n'avait quasiment rien téléchargé. Mon répertoire ne contient strictement rien d'autre qu'un fichier Makefile, avec dedans la note suivante:
"the em28xx-new driver project has been discontinued, in order to provide optimal Linux support you can have a look at [shop.sundtek.de] for fully supported Linux based TV devices.
Support for Sundtek devices is provided at [support.sundtek.de"];

Donc visiblement le projet v4l-dvb n'existe plus. Et je ne sais pas où récupérer les anciennes sources.

Heureusement, l'acquisition vidéo fonctionne parfaitement, c'est reconnu direct dès le branchement, ya rien besoin de faire (c'est un très bon point ça
Quant à l'audio, je peux la brancher sur l'entrée Line-in de ma carte mère.
Ce que je n'arrive pas à faire, c'est adapter votre ligne de commande mencodeur:

mencoder tv:// -tv \
driver=v4l2:width=720:height=576:norm=SECAM:audiorate=44100:immediatemode=0:forceaudio:adevice=/dev/dsp1 \
-o resultat.avi -ovc lavc -lavcopts vcodec=mjpeg:aspect=4/3 -aspect 4:3 \
-noautoexpand -oac pcm -endpos 01:00:00

afin de lui dire d'enregistrer la vidéo provenant de /dev/video0 (sur /dev/dsp1, la vidéo est très sacadé) et l'audio provenant de l'entrée Line-In (je sais pas qui c'est dans /dev)

Vous avez une idée? Merci

Je rajoute juste un lien vers le tutorial en question:

Autant pour moi, il semblerait que le projet ait déménagé.
Dans le tuto, il faudrait changer la ligne:
hg clone [mcentral.de]
par:
hg clone [linuxtv.org]
(source: [www.linuxtv.org])

Cependant j'ai de grosses problèmes de compilations (voir plus bas les messages de mon make). Alors soit je m'obstine à compiler v4l-dvb, soit j'arrive à adapter mencodeur pour me mixer la vidéo du dvc100 et l'audio de ma carte mère.
