Public bug reported: This is on a HP Mini 1000 (1120NR). Using Ubuntu UNR Karmic alpha-3 iso.
Generally the sound works good. The problem appears after a sound has been played when there is only silence, after a few seconds I hear a crackling noise which lasts for a few milliseconds. It happens everytime. Maybe like a powersaving problem? To test it, I just do: paplay /usr/share/sounds/question.wav I wait a few seconds and then I hear the crackling noise. Note also that in at boot-time, I think when loading the hda-intel module, there is also a crackling sound and at shutdown too. Under Jaunty, the sound didn't work but using alsa-source and compiling the modules I could make it work, there were no crackling sound except at boot time and shutdown. I remember when I was using HP MIE (Ubuntu for HP Mini's), they used a workaround to avoid that noise, they mute the volume at boot-time and at shutdown (but I'm not certain). I'm available to answer any questions. Note that I'm using the LiveCD so this is not currently installed on my laptop.
