Description of problem: after latest package-kit update I can hear cracked sound from my speakers - when I restart PulseAudio I get this: [marek@d620 Desktop]$ pulseaudio & [1] 16817 [marek@d620 Desktop]$ I: caps.c: Limited capabilities successfully to CAP_SYS_NICE. I: caps.c: Dropping root privileges. I: caps.c: Limited capabilities successfully to CAP_SYS_NICE.

Please elaborate what you mean by "cracked sound".
Also, please run "pulseaudio -vvv" and paste the output somewhere. Then, which ALSA driver is this?
[marek@d620 Desktop]$ rpm -qa | grep alsa alsa-plugins-pulseaudio-1.0.18-1.rc3.fc10.i386 bluez-alsa-4.19-1.fc10.i386 alsa-utils-1.0.18-6.fc10.i386 alsa-lib-devel-1.0.18-6.rc3.fc10.i386 alsa-lib-1.0.18-6.rc3.fc10.i386 [marek@d620 Desktop]$ what do I mean by “cracked sound” - when you called a person on their mobile phone which has poor reception, you would hear her/his voice witch crackles - something similar I can hear while I am listening to the music / watching videos or dvds. Sometimes it's less noisy other times is more noisy. I've noticed that when processor gets busy, the possibility of crackles dramatically rises. please find attached output from pulseaudio -vvv, I think this lines could explain why it happens: N: main.c: Called SUID root and real-time/high-priority scheduling was requested in the configuration. However, we lack the necessary privileges: N: main.c: We are not in group 'pulse-rt' and PolicyKit refuse to grant us privileges. Dropping SUID again.

Created attachment 328332 [details] output of "pulseaudio -vvv"
also, I've noticed that when I use xine backend in totem, I get less crackles then with gstreamer backend. Although when I watch a movie with 5.1 multichannel sound, I get more crackles even while using xine backend. I can confirm this issue on two different laptops: Dell Latitude D620 and Dell XPS M1330, both running Fedora 10 with kernel 2.6.27.7-134.fc10.i686 - I can't upgrade to -159 as with this kernel I'll have no sound in my headphones on both machines.
I am seeing these errors in /var/log/messages, also, but on an x86_64 architecture. rpm -qa |grep -i alsa alsa-plugins-pulseaudio-1.0.18-2.fc10.x86_64 bluez-alsa-4.22-2.fc10.x86_64 alsa-utils-1.0.19-1.fc10.x86_64 alsa-lib-1.0.19-1.fc10.x86_64 rpm -q PolicyKit pulseaudio PolicyKit-0.9-4.fc10.x86_64 pulseaudio-0.9.13-6.fc10.x86_64 From /var/log/messages: pulseaudio[2610]: main.c: Called SUID root and real-time/high-priority scheduling was requested in the configuration.

Hmm, PA f10 actually has pa 0.9.14, not 0.9.13 as you seem to do. Could you please make sure to run the latest packages?
