I'm using Ubuntu 9.10 32-bit version. I've seen this bug also. I've tried to comment "options snd-hda-intel power_save=10 power_save_controller=N" , but that didn't help. Most useful was changing "options snd-hda-intel power_save=0 power_save_controller=N" to "options snd-hda-intel power_save=0 power_save_controller=N". But even after this the bug still sometimes appears. Before playing sound I here a silent cracking noise, same noise I hear about 5 minutes after playing the sound (Tested with gajim sounds and playing music when pointering a music file in nautilus).
