This bug is still present in precise. However, the following workaround works for me:
* log in
* echo 1 | sudo tee /sys/module/snd_hda_intel/parameters/power_save
* echo Y | sudo tee /sys/module/snd_hda_intel/parameters/power_save_controller
* pkill pulseaudio
* log out & log in again (so pulseaudio gets restarted)

However just inserting "options snd-hda-intel power_save=1 power_save_controller=Y" in /etc/modprobe.d/alsa-base.conf doesn't work. Why?
