The modprobe.d/ structure is different, so I've modified /etc/modprobe.d/dist-alsa.conf adding the following line:
*options snd-hda-intel model=hp-dv5 enable_msi=1 * Please, note there are different value for the model= parameter and I've not found a good source of documentation helping the choice. Try google with the specific string model of your laptop and "sound+linux" The problem here arise from the chip-set being a Family with different implementation schema; similar products (eg Pavillion dv from HP) may use different values.
