Hello,

Thanks for your really fast answer. I used the line below ; I don't know=20
if they are correct, but it works fine !

It remains one problem however : I volume change has no effect. The same=20
with xine-ui, I can change volume but it has no effect. Using alsamixer=20
to change volume works fine. Any idea ?

/* use alsa */
	xine_config_register_string(xinePtr, "audio.driver", "alsa", NULL,=20
NULL, 1, NULL, NULL);
	xine_config_lookup_entry(xinePtr, "audio.driver", &parametre_xine);
	xine_config_update_entry(xinePtr, &parametre_xine);
=09
/* use sound device "D00" */
	xine_config_register_string(xinePtr,=20
"audio.device.alsa_default_device", "plughw:D00", NULL, NULL, 1, NULL,=20
NULL);
	xine_config_lookup_entry(xinePtr, "audio.device.alsa_default_device",=20
&parametre_xine);
	xine_config_update_entry(xinePtr, &parametre_xine);
