Description of problem: Whenever I start playing something, there's a single crack before the sound starts. For example, when I'm using Pidgin every notification starts with a cracking noise. However, if I'm in Rhythmbox there's a single crack only when I start playing, there's no crack between songs and there's even no crack in Pidgin's notifications while playing. It happens with every sound, even in the gdm screen when asking for the password and the login sound. It seems to be something with the sound card waking up. The problem happens with both speakers and headphones. Version-Release number of selected component (if applicable): pulseaudio-0.9.15-17 How reproducible: Always Steps to Reproduce: 1.Play any sound 2. 3. Actual results: Cracking noise before sound starts Expected results: Sound plays without any crack Additional info:
Sounds like a driver/hw artifact that happens when PA initiailizes the audio device. Please appand the output of alsa-info.sh --no-upload here.

Do you need any other information for this bug?
Audio powersave was enabled by default in kernel 2.6.30 ... I assume the problem started after updating the kernel? You can disable it like this: # echo "0" >/sys/module/snd_hda_intel/parameters/power_save It's now disabled by default in kernel 2.6.30.7-59 and later.
Thanks for your answer! Yes, the problem started after an update, but I thought it was pulseaudio's update and not the kernel.. Maybe both updated at the same time and I just blamed pulseaudio. I did what you suggested but the problem is still there.

This workaroud solves the problem, but when I restart it's back again. Is there a way to set the parameter to 0 permanently?
