The sound card in the laptop Asus A6B00VC does not work correctly (no sound nor any channel in alsamixergui apart the microphone which seems detected)

(there's a microphone included in the webcam of this laptop as well, but it makes quite a lot of modules for sound...)

for the complete dmesg : see http://baud123.free.fr/mdv/dmesg_asus_A6B00VC_snd_pb.txt and for full lsmod : http://baud123.free.fr/mdv/lsmod_full_asus_A6B00VC.txt other diags : http://baud123.free.fr/mdv/

I've tried putting noapic acpi=off in /etc/lilo.conf as well...

I've begun making tests, see http://wiki.eagle-usb.org/wakka.php?wiki=InstallMandriva2006

Maybe this card is new (rev 04) and not (yet) recognized by module snd-hda-intel ? (could it be added to ldetect-lst ? not sure it will be suficient though...)

anything else to provide to help diagnose ?
