hda-intel, like the infamous ac97, is a widely-used codec, and the
kernel module supports a whole lot of different devices. I don't have
a lot of time to check right now, but a quick grep on the sources
shows your card's support is included in
sound/pci/hda/patch_sigmatel.c. From a quick search, the list of
possible options can be found here:

and your best bet could be dell-m44 (similar to 4400, but marked as
Inspiron) or dell-m43 (near to 44 but marked as Precision).
HTH,
