The one rule for hda intel hardware is to use 3 periods or more. 2 
does not work very well (if at all) so you are almost certainly already 
doing that. Hda intel is by design quite crappy....

There are some parameters you can pass to the kernel module when it
loads that apparently makes it work when it doesn't, I don't know if
those would help with an already working configuration.
