I can confirm this bug. Seems I have exactly the same Notebook with the same hardware. Except my kernel is a little newer. This may be helpfull. Dmesg gives:
[ 33.588271] hda_codec: Unknown model for ALC660VD/ALC861VD, trying auto-probe from BIOS...
Tried the originaly delivered BIOS Version and the lastest. Still no sound ...
