After switching to Ubuntu 12.04 I use Vlc only with ALSA, so this bug is
not affecting me any more. Thus, I changed the status to Invalid.
** Changed in: pulseaudio (Ubuntu)
Status: Confirmed => Invalid

Title:
Crackling sound and higher CPU usage in VLC player using pulseaudio
Status in “pulseaudio” package in Ubuntu:
Invalid
Bug description:
Binary package hint: pulseaudio
My systems run Ubuntu 10.04 64 Bit and 32 Bit (all clean install) and
the problem is the same on both the laptop and the desktop computers.
Crackling sound together with higher CPU usage occurs when playing
some songs (mp3) or video (avi) in VLC player using pulseaudio plugin
output. With some songs or videos crackling is more disturbing than
with others, but I didn't find any pattern - anyway it seems that the
sound is never totally clear. If output is changed to alsa, VLC uses
alsa pulseaudio plugin and crackling is gone, but after some time
audio automatically gets disabled and I need to disable sound track
and than re-enable it again via VLC "Audio->Audio Track" menu
(sometimes it doesn't help).
I recently find a workaround which always works for both my computers
- When I delete "~/.pulse" folder (this needs to be done after each
restart of the computer) and then run VLC crackling is gone no matter
which output I set (ALSA/Pulseaudio) and also audio track is not
automatically disabled after some time.
