I also confirm the same behavior on a Latitude D830 under Gutsy:
2.6.22-12-generic
[ 33.004313] hda_intel: azx_get_response timeout, switching to polling mode... [ 33.075375] hda_intel: azx_get_response timeout, switching to single_cmd mode... [ 43.812505] hda-intel: no codecs initialized
Sound worked in Feisty, but not Gutsy, just as everybody else above has described.
