I was able to fix my sound problem in up-to-date Hardy Heron following a guide from the German magazine FreiesMagazin (http://www.freiesmagazin.de), June 2008, on page 19:

1) Create the following file: /etc/modprobe.d/snd-hda-intel.modprobe
2) Append at the end of the file following entry: options snd-hda-intel model=3stack-dig
3) Append at the end of the file /etc/modprobe.d/alsa-base following entry: options snd-hda-intel model=3stack-dig
4) Edit following file: /etc/default/acpi-support and change the following entry:

# Add services to this list to stop
# them before suspend and restart
# them in the resume process.
STOP_SERVICES="alsa"

5) Reboot your computer

After this, sound worked for me after suspend to ram and hibernation.
Note that the model in the above entry has to match the sound chip in your computer. Intel high definition audio (HDA) allows for different chips to be used. Your chip can be found via following command:

$ aplay -l

A list of drivers can be found in following file:

$ zless /usr/share/doc/alsa-base/driver/ALSA-Configuration.txt.gz

There are usually several options, try them all to find your matching driver.

OS: Kubuntu / Ubuntu Hardy Heron
Hardware: Core2 Duo T7300, Intel Santa Rosa, i965 graphics chipset
Laptop: Littlebit Sepia X35 (Asus Z37E)
