Bug Description

Binary package hint: pulseaudio

I have a completely up to date karmic system (as of 2009-oct-05).

Whenever I start a movie (any movie file or audio file triggers it) in totem I first get a high crackling noise and afterwards the movie audio starts normally. I can then watch the whole movie just fine with no audio problems, it's just that very moment when the audio system initializes start is the problem. The strangest part is that if I re-launch totem right away then it doesn't make that noise on startup, but if I wait for a minute or so and then I try to launch totem, boom the sparkling / crackling noise happens on startup again.

I'm thinking either, it's because the sound system has some power save mode that activates after a while; or maybe there is some sound buffer that get's accidently filled with obscurely high values (that sound aweful when played back).

Same thing happens when I start any WINE application (even if it's not an audio app) and it even happens when I run the alsa-info.sh script (high sharp crackling / sparking noise is heard). On every boot I also get a loud sparking noise when the audio system first initializes. Also every time someone goes online on Skype I get the sharp loud sparkling sound as well. That particular one is the most annoying actually because the crackling noise has a lot high volume than a normal sound and when triggered by Skype you're usually not prepared for it so I tend to get kind of startled by it.

My alsa-info.sh is available here:

Also note that there are no sound related errors printed to dmesg when the crackling noise happens (nothing at all is appended to dmesg in fact).

If I disable power saving for my Intel HDA by putting "options snd-hda-intel power_save=0 power_save_controller=N" in my "/etc/modprobe.d/alsa-base.conf" then the crackling / sparking noise goes away. FWIW, this is a stationary computer so I don't even care about power saving that much. Sure it's nice but only if it can be implemented with zero sparks/noise side effects.

I experienced the same problem. In my case "options snd-hda-intel power_save=0" (without the power_save_controller option) did the trick.
