Bug Description
Binary package hint: pulseaudio
After some unknown period of time (I haven't been able to find a pattern here), an otherwise working pulseaudio daemon starts crackling, popping and stuttering during playback. It can suddenly start happening while I'm playing audio (doesn't matter what application) or while I'm not playing audio (like overnight, and I come back to a distorted playback). Restarting pulseaudio (pulseaudio -k ; sleep 5 ; pulseaudio -D) seems to fix it (until it happens again).
ALSA doesn't need restarting or reloading in this situation, just pulseaudio, and the applications that use it. So whenever I restart pulseaudio, I have to restart the browser and music player.
(incidentally, I tried to run the utils_alsa-info.sh, which seemed to run fine, but it didn't report where it uploaded the info, so I'll try to attach the relevant file here).
I do get the following errors in user.log when I restart pulseaudio:
Feb 26 07:42:17 krazykat pulseaudio[17762]: alsa-util.c: Device plug:dmix doesn't support 44100 Hz, changed to 48000 Hz.
Feb 26 07:42:17 krazykat pulseaudio[17762]: alsa-util.c: Error opening PCM device hw:0: Device or resource busy
Feb 26 07:42:17 krazykat pulseaudio[17762]: module.c: Failed to load module "module-alsa-sink" (argument: "device_id=0 sink_name=
...but sound works (for a while) after that, and the bug searches I did on those errors were all about sound not working.

There are a couple things to note from your pasted daemon output:
1) plug:dmix is in use - did you modify /etc/pulse/ default. pa to use that for module-alsa-sink? If so, please attach your modified /etc/pulse/ default. pa;
2) the symptoms are very probably related to bug 330814
As always, I need to see pulseaudio -vv output.
