Description:

When using pulseaudio with the equalizer enabled (I've followed the instructions from the wiki https://wiki.archlinux.org/index.php/Pulseaudio#Equalizer), the daemon randomly goes 100% CPU and stop responding (no audio, qpaeq and pavucontrol can't connect to the daemon, can't kill the daemon with "pulseaudio -k" command).

Additional info:

package version: pulseaudio 4.0-6
I've tested only the x86_64 package on 2 different machines (both are netbooks with Atom CPU and HDA audio with Realtek controller).
The problem occurs randomly: pulseaudio could became unresponsive immediately or after many minutes (in some case in more than half an hour).
With the equalizer disabled, I've played music for more than 12 hours without any problem (the CPU usage by pulseaudio keeps below 3%).

Steps to reproduce:

-enable the equalizer (I've enabled it in default.pa configuration file)
-start playing music
