After upgrade to Rawhide, both Rhythmbox playing mp3s and Flash plugin playing last.fm seem to have a crackle in the left channel. (Or maybe right, if my speakers are backward ;-)) I thought my speakers were dead at first so I changed to another set, same issue. So it's in two different apps/codecs, two different sets of speakers, and appeared on upgrade to rawhide, if that helps narrow down the problematic piece of code. I'm attaching scsconfig.log. It's an Intel onboard sound card.

This seems to be gone at the moment, I've made two changes: 1) I rebooted and 2) I put myself in the pulse-rt group. I don't know which one solved it. Will close the bug if it stays solved for a bit.
I see the kernel drivers are only 1.0.16rc2 and alsa-lib is 1.0.16 (the final). Maybe you can update the alsa-drivers by hand. Another thing what comes to my mind is to play through HW output - try to write something like this to /etc/asound.conf: pcm.!default { type plug slave { pcm hw:0,1 }} ctl.!default { type hw card 0 }
ehh, or remove "/etc/alsa/pulse-default.conf" from /etc/alsa/alsa.conf ;-)
