to reiterate what has already been said by a couple others:

you might need to add the following line to your /etc/modprobe.d/alsa-base (i certainly had to!) *in addition* to installing the linux-backports-modules package:

options snd-hda-intel model=<MODEL>

where <MODEL> is an entry found in /usr/share/doc/alsa-base/driver/ALSA-Configuration.txt.gz (for my dv9500t, it is "model=hp" -- search for "snd-hda-intel" in the file...). note that you may have to make a guess as to the entry to which model your particular laptop corresponds.

in addition, some people have reported needing to add "position_fix=1" in addition to "model=<MODEL>" -- whether or not you require that will likely come down to trial-and-error.

best of luck everyone!
