problème xdtv alsa

[limax <lacuisinedemax@free.fr>]

bonjour

J'ai un problème de configuration d'alsa.
J'utilise une carte son augyLs et le module utilisé est ca0106.
J'ai utilisé alsaconf pour configurer la carte son. Je ne peux lancer xdtv avec
alsa. J'ai ceci à la fin 

*** AUDIO DEVICE TYPE = alsa
*** GRABBER DEVICE TYPE = v4l2
xdtv: simple.c:698: snd_mixer_selem_get_capture_switch:  l'assertion « elem » a
échoué.
Abandon

Je ne peux pas lancer aussi qjack avec la capture.
Si quelqu'un peut m'aider merci
